Your airlines' policy about the use of automation during flight?
 
Our company's OM says that, generally, we should use the AP during cruise and as much as possible during abnormal situtions (failures). But, in climb or approach, when workload, weather conditions and crew fatigue permit, pilots
can fly manually in order to maintain their basic flying skills

And believe me, we make good use of this opportunity! :ok:

I'm really interested in what your company says about the use of automation. It would be nice it you could copy and paste your airline's policy about the use of automation in your answers.

WhiskeyKilo 1st Jun 2011 00:36

I'm not currently a member of an airline yet, but I remember in an aviation magazine that a 'well-known' (I don't want to name names) european airline said 'Manual flying is only to be undertaken in the most extreme of circumstances' :ooh:

Capn Bloggs 1st Jun 2011 02:05

My outfit:

"Practice with less than full automation is prohibited during normal line operations".

john_tullamarine 1st Jun 2011 02:43

I recall back to the introduction of the 733 to replace the 732 in one airline .

After an initial, short, Flight Standards romance with the bells and whistles, the boss issued an edict along the lines of "Fly it how you prefer, but know how to do both - make it work well and don't embarrass me".

Appeared to work well.

Some pushed buttons to their hearts' content (but, consider, they had the manual skills well and truly established previously).

Others (including folk like me) preferred to push and pull on the yoke. Indeed, more than a few of us would hand fly entire sectors on the shorter routes, preferring to use the autopilot for important things .. like having lunch. I recall, on my check to the line, flying all bar the last sector by hand. The checkie, on the other hand, opted to fly a sector and preferred to spend his drawing pictures on the FMS - no problems, to each his own.

I suggest that, overall, there is a cost argument to emphasise the automatics. However, that cost argument is only part of the overall potential cost argument. Perhaps the optimum position is somewhere between the two extremes ?

Now, I have never flown Airbus so I cannot make any specific observations. However, I recall when the 320 was being introduced to Oz, the then Regulator's TP spent quite a bit of time on the aircraft and was utterly seduced by its magic. On the other hand, having flown with him on a number of occasions on test work, I have to observe that his stick and rudder skills were somewhere between very excellent and exceedingly excellent .. he was not the sort of chap to let his guard down with button pressing to extremes.

Denti 1st Jun 2011 05:42


Continuous use of automatic systems leads to loss of basic knowledge of power settings/pitch attitudes and reduces the ability to fly accurately with a low workload. Pilots should therefore regularly fly the aircraft manually, with em- phasis on manual departures/ approaches with and without the flight director. However these intentions should be briefed and only performed when good weather and low traffic conditions prevail.
Briefing consists usually of a simple "are you ok with it?" to make sure the other guy is in the loop and can cope with the slightly increased workload. What good weather conditions are and how to define low traffic conditions is left to the individual pilot.

sabenaboy 1st Jun 2011 07:30

Why would using automation all the time be cheaper?

I have read this argument also in another thread.
Frankly I would be amazed if flying automatically all the time would turn out to be cheaper! I don't expect there to be any significant difference in the costs, but if asked, I would expect it to be the other way around.

Handflying doesn't stop us from flying FMGS calculated optimum speeds or taking advantage of calculated optimum descent point to respect some alt constraint further down the approach.

On the contrary, I believe that the fact that we are very often flying (shorter) visual approaches, saves the company a lot of money!

Try dispatching an airliner with A/P inop (if within the MEL)and see the reactions; for the punters down the back, not a comfortable experience and I am talking hand flying during cruise stages as well!!

Handflying uncomfortable?

Well, I couldn't take our 320's in RVSM airspace without A/P, but if the ship was perfectly fine apart from the A/P, and no other adverse conditions were expected, I wouldn't mind taking it on a short hop (let's say, < 1,5 hrs) below RVSM back to home base for repairs.

And the people in the back, you ask? They wouldn't complain! They wouldn't even notice!

I would refuse to take it on a long flight without A/P and on any flight leaving base, but that would be because I would be worried about my comfort, not the passengers'! :ok:

DuneMentat 1st Jun 2011 09:17

From our ops manual:


2.1.22 Use of Automation
While pilots should make full use of the highest level of automation available to reduce workload, this must be balanced with the need to maintain manual handling proficiency. At all times the level of automation being used must be appropriate to the task.

At any stage where the aircraft response is not appropriate or adequate, the
automation must be disconnected with the subsequent reversion to manual flight.

When conditions and workload allow, pilots may elect to hand fly. This must be briefed as part of the departure or arrival briefing and remains at the discretion of the Commander.

sabenaboy 1st Jun 2011 11:03

@DuneMentat

So how is that being applied in day to day operations in your company?

Do you regularly handfly raw data app's? Or is that an exception, rather then something you regularly do?

FlightPathOBN 1st Jun 2011 14:22

Ask any SW pilot...the motto "fly it like a 200" is not only a mantra, its a necessity....:}

A37575 2nd Jun 2011 06:44

Actual scenario in a 737 NG. Visual approach to Sydney at 30 degree angle to ILS track. 17 miles from touch down and closing the localiser. The F/O as PF asks captain for permission to disengage AP for hand flying practice because of up-coming simulator instrument rating. Captain says no problem go ahead. F/O surprised, says gee thanks - most other captains don't allow me to hand fly.

But she does not disengage the AP. Captain reminds her. F/O says I won't disengage AP until it has completed localiser intercept in case I overshoot the centre-line. Eventually the aircraft is established on ILS and F/O switches off the AP. Captain says aren't you going to turn off the flight director to practice your raw data hand flown visual approach? No says the F/O, I will need the FD on in case of a go-around....

It is this sort of timorous attitude by some pilots to what are basic flying skills is the direct result of blind adherence to automatics and nothing but automatics. Blame the company simulator training environment where 90 percent of flying is on automatic pilot and associated button pushing.

Is it perhaps because the powers that be in the top echelon of training departments, cannot be bothered to read accident reports where loss of control because of poor instrument flying skills has been the problem? Certainly there has been no shortage of relevant accidents in the past few years. The increasing accent on superfluous politically correct SOP minutae seems to blind the trainers to the pressing need for pure flying skills.

One wonders why companies continue to encourage this lemming type attraction to automatics when Blind Freddie himself can see it leads to lack of self confidence in manual instrument flying skills?

As the ever increasing trend to hiring first time cadets into the second in command position on jet transports becomes the norm, loss of control accidents will also become the norm and inevitably due to lack of pure flying ability.

sabenaboy 2nd Jun 2011 10:09

Don't blame low time cadets, blame the training department!

I don't think the low time cadets are the problem, but more likely the training department. My company also hires the low time cadets fresh out of flight academy. Most of them do a great job at handflying, once they're released on line.
Here's what I wrote about it in an other post.


In my company it's done like this: Starting in the type-rating sim sessions the F/O's in training are learned to fly the Airbus manually (A/P, F/D & A/THR off) on many occasions whenever the exercise permits it. (And, for training, having one engine out is NOT a good reason to keep the A/P on. := ) Then, during base training they'll fly a few touch and go's, again without the automatics. Later on, during the initial line training, they will be asked to fly manual raw data approaches, whenever the conditions permit it. Believe me, once they're fully released on line they'll handfly the A320 pretty well, or ... they won't be released on line. :=

Unlike many others my company encourages pilots to keep their handflying skills up to date. Most of the time, I don't have to suggest my F/O's to turn the automatics off. they will have asked me before if they can. More often it happens, especially with the newly released kids, that I have to suggest them that it would be wise to fly with the automatics on when the metar warns us about low clouds and moderate visibility or when flying into a busy airport we are not familiar with! :p It's not they are not smart enough to know that, it's just that they were so used to raw date flying during their training, that using the automatics for approach has become the exception, rather then the rule. :p

I'll admit that sometimes those new F/O's are not so great in using the automatics. For instance, the first time they have to intercept a G/S from above with the A/P, they will often have a problem. Not amazing, they've trained it once in the sim and then they were expecting it! So confronted to this situation these guys (and girls) will disconnect the A/P when it captures the initial approach alt before the G/S iso using the Airbus procedure for this. (dialling the altitude up and using V/S to get to the G/S.) Oh well, manually intercepting the slope and then re-engaging the A/P gets the job done just as well and it gives me something to talk about during a friendly post-flight debrief. :ok:
There is really no excuse for Airlines who forbid their pilots to keep their raw data handflying skills up to date.

d105 2nd Jun 2011 10:28

Company policy is maximum use of AFDS with FD. Stick to LNAV / VNAV.

Company manual does not forbid handflying, but that is seen more as the lawyers covering the company in case something goes wrong with the automatics and it turns out people can't fly a damn kite anymore.

My personal policy is during summer usually raw data takeoff and approach/landing unless weather or other limiting factors require my attention to be on other things than just purely flying.

During winter usually automatics on until intercept on final, then manual flying. It seems a bit silly to me to be following radar vectors manually while there's nothing outside to look at but clouds, clouds and more clouds.

Denti 2nd Jun 2011 11:23

AS373575, as Sabenaboy said, the low timers are not a problem. We do take on our own MPL students and low timers from outside the company as well. The posted excerpt of the OM applies to them as well. And during simulator events we have to do raw data handling skill training as well, lately basic IFR flying skills again, but over a 3 year period that will change around a bit.

It is not about the hours the pilots have you hire, it is about the training they receive and the flight ops culture on the line.

Your example might point at bad system knowledge as well, after all in the case of a G/A you have the FD auto-pop up anyway, no need to have them switched on for that.

despegue 2nd Jun 2011 11:48

Hey Sabenaboy,

Great to hear that times haven't changed since our Sabena times!:ok:

I mostly fly raw-data u to cruise-level unless wx or traffic is an issue. Most guys here are ok with it, with the occasional FO who complains about workload:rolleyes: (get another job then if you can't handle it, you would never have passed a Sabena check) or is lecturing me about how mr. Boeing designed the aircraft to be flown through the autopilot (biggest bull$hit I've ever heard:ugh:)...

Proficient rudder-stick pilots are more economic than automation operators. Fact.

Any airline that prohibits ther pilots to FLY, should be put on the blacklist as they are more dangerous than most which are already on it.

GlueBall 2nd Jun 2011 16:50

:ooh: I've never heard of all three [3] A/P being inop on the B747. . .

Slasher 3rd Jun 2011 02:32

Back in the trusty 732 and 734 I'd sometimes fly a short trip
completely raw data and just load the box with dep and dest
airports. It was fun, even with the awestruck kids wondering
how the hell its possible to fly without AP FD LNAV VNAV and
AT engagements.

But with the scarebus 320 suck-squirt I get no satisfaction at
all from hand-flying the damn thing, except for maybe TO to
TOC and the odd raw data VOR or ILS, starting with taking
out all the gizmos below 10,000. The flight controls are in a
computer-driven form of CWS anyway so what's the point? :hmm:

If you are looking for seat-of-the-pants flying, with the need to trim manually, you’re on the wrong aeroplane, Slasher! :ugh:

And if we really want to relive our youthful experiences of flying big aeroplanes with stick-to-surface controls (no intermediate feel-units, no PFCUs, no servo-tabs, nor even any balance tabs), we’ll have to try and persuade one of those Canadian or third-world operators to trust us flying one of their precious remaining C-46s or C-47s.

You know very well that the essence of flying any jet is the relationship between pitch, bank, IAS, FPA, and thrust: and its variation at different altitudes and weights. (On all EFIS Airbuses since the A310 (1983), you can obtain FPA from the raw “bird” and also get a good idea of the AoA.)

There is a strong argument, however, for using the automatics in busy terminal areas. What worried me most in my many years on the A320 was the majority culture of delaying AP disconnect on a visual ILS approach until about 300ft, and then disconnecting it for a manual landing − retaining A/THR throughout. Once the landing checks are done, there is little for the PNF to do except monitor the flight-path and keep a lookout, so for the PF to minimise his/her workload in good weather is no longer necessary − unless fatigued.

Chris

Al Murdoch 3rd Jun 2011 16:52

I love flying raw data and do so whenever possible. But flying around busy terminal areas like London without the gifts that Boeing gave us is just asking for trouble, unless you really, really have to.
The key to maintaining your skills by flying without using the gadgets, is knowing when it is appropriate to do so. Sometimes it is useful to remember there are fare paying passengers in the back.

Old Smokey 4th Jun 2011 11:24

A very nice post from Al Murdoch, which, to me, summarises the essenence of this whole discussion. Al's attitude is exactly in line with my own. I too, enjoy and take every opportunity to practice hand flying when appropriate, but in very busy airspace or marginal weather firmly believe that the aicraft must be operated by the safest and most accurate means possible, and that, on most (but not all) occasions implies the use of MODERN automatics.

John_Tullamaine, in one of the posts here, has stated that attitude and capability is very much a 'pilot era' thing. (John's backround and mine are very similar). For those of us from the era where hand flying was the safest and most accurate means possible, we have no discomfort in a modern highly automated aircaft in operating either way, the old or the new. It is no fault of the younger pilot entering the industry on a highly automated type to place a heavier reliance on the automatics.

I have always believed that an aircraft should be flown as the manufacturer intended.

When I learned to fly on the Tiger Moth, I flew it 'by the seat of my pants', that's what De Havilland intended, and that's what I did.

When I flew the DC3, I flew it by hand with the rather rudimentry insrumentation available, using the very primitive Auto-Pilot (not much more than a wing leveller) for a bit of relief during cruise. That's what Douglas intended, and that's what I did.

When I flew the F27 and Viscount, with a much improved (Sperry) Auto-Pilot, automation had only increased to improved en-route capability (Airspeed and Altitude Hold.....wow!). Terminal area flying and approaches were very much a hand-flown thing. That's what Fokker and Vickers intended, so that's what I did.

Jump a generation to the DC9 and B727. Very much improved Auto-Pilot (singular) and Flight Directors enabled much more accurate Automatic and Manual flight, but with zero redundancy, one had to be EQUALLY proficient with Automatic and hand flown flight. That's what Douglas (sniff!:() and Boeing intended, so that's what I did.

Jump over the A300 (my first Auto-land aircraft) to the current era where I fly the B777. Boeing incorporated very accurate and reliable automation with an incredible capacity for redundancy (7 sources of electrical power, 8 IRS units, 2 GPS units, 3 Flight Director backups, and a wide degree of PFD redundancy). How did Boeing intend that the aircraft be primarily flown? - By optimum use of automation, that's how, and that's what I do.:ok: The degree of redundancy is the deciding factor. Doing a 1 engine, TAC off, Raw Data ILS is a lot of fun, and good for confidence, but is such training necessary? ..... Absolutely NOT! (Excluding the TAC off because it has no back-up).

So, apart from self satisfaction, why do I still take every chance to hand fly? It's NOT because of possible Automatics failure, considering the mind-boggling redundancy, the chances of being 'down' to raw data are trillions to one against such a possibility. It's because there are still several manoeuvres which still call for the pilot to fly - The Visual Approach, and the Non Precision Approach (NPA). From the Base turn onwards (for the Visual Approach) and from the MDA onwards (for the NPA) manual flight (ideally with the Flight Directors OFF) is still essential!:ok: Add to this list (1) GPWS escape, (2) Wind Shear escape, (3) TCAS avoidance, and (4) Ground Equipment (such as ILS) malfunction, all SERIOUS situations, none can be handled by the Automatics in current generation aircraft, so Pilot Proficiency in hand flying remains essential, even if the Automatics remain fully functional.

So, the bottom line is, fly the aircraft as the manufacturer intended in normal operations, tempered with a good respect for the level of redundancy, and in the full realisation that there remains many areas (as described) which cannot be handled by a fully serviceable Automatic system. The pilot's proficiency in manual flight is the LAST line of defense.

When I go to my paid work, I make full use of the B777 automatics, particularly in inclement weather and crowded skies, but avail myself of every chance to 'get in' some hand flying. When I still fly the Tiger Moth on my time off, I fly it by the seat of my pants. That's what Boeing and De Havilland intended!:ok:

Old Smokey

That sounds fine to me! Am I correct in assuming that 'some hand flying' includes switching A/THR and F/D's off?

So what exactly does your company's OM say about the use of automation?

A37575 4th Jun 2011 12:15


The pilot's proficiency in manual flight is the LAST line of defense.
In recent years, Loss of Control has superseded CFIT as being the largest cause of aircraft accidents. That being the case, the LAST line of defence has more holes in it than Reasons Swiss Cheese theory...

Being selective I know, but the whole argument for automatics skills versus pure flying skills hit home when the CVR captured the voice of the captain of the doomed Egypt Air Boeing 737 still screaming "engage the autopilot...engage the autopilot" ....silence - end of recording. :eek:

sabenaboy 4th Jun 2011 13:08


the doomed Egypt Air Boeing 737
I suppose you mean the FLASH Airlines 737 which crashed after TO in Sharm El Sheik...

Old Smokey 4th Jun 2011 14:02

Sabenaboy,

To answer your 2 questions -

(1) 'some hand flying' includes switching A/THR and F/D's off, Yes, including all combinations of 'complete' raw data, and 1 of the 2 afore-mentioned OFF, and

(2) So what exactly does your company's OM say about the use of automation?, Use it fully and appropriately. Pilots are free to practice their hand flying / raw data skills in appropriate conditions, providing that optimum safety is not compromised and the PNF's work load is not unreasonably increased. (That's a summary of a quite lengthy discourse).

PLUS, Pilots should have no hesitation in reverting to Manual Flight should the occasion call for it (Again, a short summary).

Added as a Post Script - Quite a number of Company OM procedures call for Manual Flight with FD off, and Manual over-ride of the Auto Thrust (mainly those items addressed in my original post).

Regards,

Old Smokey

Microburst2002 5th Jun 2011 15:33

Nothing written in any of the airlines I have flown with.

In those where there were "Sabena boys" I did enjoy a lot of hand flying and that is one of the reasons I consider those captains probably the best I've flown with. And they were all from a good cadet program, btw.

In the others, very seldom I fly with a "brave" captain who encourages hand flying, and very frequently with "not so brave" ones who directly deny that "right" to me.

In one of them, their motto (non written) is "do not degrade the airplane capabilities".

a last thought. The Airbus FBW is not a CWS. The only real difference is that you don't have to trim and you maintain bank angles very easily. Otherwise, you have to set a pitch and thrust, and use the brain, like in a cessna.

Prince Niccolo M 6th Jun 2011 11:30

Sabena boy. Thanks for the correction - my error.

parabellum 6th Jun 2011 21:31

In todays modern aircraft it is important to fully understand the capability of the automatic systems. One of the biggest sins I have seen is a captain disconnecting auto pilot and throttle and announcing he will hand-fly when an emergency occurs!!! That may have been OK in the days of the flight engineer but the FE was got rid of on the basis of system redundancy and high levels of automation, so that automation must be used when appropriate. When the captain* disconnects and says he'll hand fly he is overloading the FO, who has to monitor and react as requested to the handling pilot as well as handle the emergency. The captain has chosen to overload himself by both hand flying and trying to monitor the emergency drills. Sadly there are several examples of a failure to properly monitor due to work overload when the use of automatics would have freed up a lot of capacity to properly analyse and monitor abnormal situations.

Regarding culpability, the manual will always be written in such a way that if an emergency occurs and proper use of the automatic systems was not utilised then the pilot will be to blame, on the other hand if use of automatics was not the best option then the pilot will be to blame! Sod's law, that is the Managerial CYA mode in full operation!


The recent A380 incident in Singapore shows that additional eyes and brains on the FD can reduce the workload, (five on the flight deck), if they know what they are doing.

*assuming captain retains or takes over PF duties.

FerrypilotDK 6th Jun 2011 22:12

I have seen guys come from the airlines who simply would refuse, as they know they cannot fly(!) A generalisation, but when you see that some of the "outfits" referred to here nearly forbid flying except in extreme circumstances....the story tells itself! Then there are NDB approaches and circle to land....runways that are both narrow and relatively short.....all great for variation and skill. Our company (when I had a tedious commuter gig) had no autopilots installed, so every flight was hand-flown and some of the legs were 3 hours......

Call me next time then, no complaints!

:cool:

FlightPathOBN 7th Jun 2011 00:23

Every single system is designed to reduce the workload and the mundane... automation is to help the pilot fly the aircraft...

Any reasonable person would understand the need to provide oversight of the automation, understand the mechanics of the solution, and disco when applicable.


The recent A380 incident in Singapore shows that additional eyes and brains on the FD can reduce the workload, (five on the flight deck), if they know what they are doing.
Really...the ONLY reason...(while the press may have had some fun with that, I am sure that no one has an expectation that 5 on the flight deck was the reason for the outcome)

You only need two to know what they are doing, and one of those to be able to follow commands.

parabellum 7th Jun 2011 11:05


...(while the press may have had some fun with that, I am sure that no one has an expectation that 5 on the flight deck was the reason for the outcome)


Nor did I suggest it was, the bulk of my post was about the proper use of automation to minimise workload and avoid overload. Extra eyes and brains can be useful, if they are available, but with proper use of the automation the maximum attention can be paid to the abnormality/emergency.

Denti 7th Jun 2011 11:12

parabellum, nobody suggests otherwise. You always have to be proficient in autoflight as well. However, many abnormals degrade or shut off autoflight functions, and especially in those cases with exceptional high workload manual flight only works well if the pilots are proficient in manual flight. To be proficient in manual flight you need to keep your training up, what is better than to simply do it on the line?

Of course a professional pilot always should be proficient both in manual flight and autoflight usage. However there are some airlines that discourage the crews to use manual flight, and i guess this thread is about this point. Twice a year in the simulator for a couple minutes is simply not enough training.

And of course any additional pilot on the flightdeck helps in an non-normal situation.

A37575 7th Jun 2011 13:47


Twice a year in the simulator for a couple minutes is simply not enough training.
Last year, a Boeing Company check pilot talked to pilots of a major Hong Kong based airline. In his travels, he noted that some airline pilots tended to avoid the opportunity to practice hand flying skills until the very last minute before a simulator session. This was a waste of time - he said - because manual flying skills had to be maintained throughout the year and that a hand flown ILS in good weather after months on autopilots did nothing for basic flying skills.

misd-agin 7th Jun 2011 22:36

Use of automation to the extent necessary is the basic policy.

If guys turn the a/p on shortly after takeoff (decent weather)I'm worried about their skills. My concern is frequently correct.

If the guys don't turn the a/p off until the a/c is stabilized, gear down, final flaps, I'm worried about their skills. Again, my concern is frequently correct.

If the guys hand fly in bad weather I'm thinking "what are you trying to prove?" Use the automation to the extent necessary!

BGQ 8th Jun 2011 20:57

Automation Philosophy
Introduction
Automation is the replacement of the human function, either manipulative or
cognitive, with a machine function. The sole purpose of automation is to aid flight crew in doing their job.

Flight crew are the most complex, capable and flexible components of the air
transport system, and are best suited to determine the optimal use of resources in any given situation. They must be proficient in operating their aircraft in all levels of automation, and must have the skills needed to move from one level of automation to another.

Automation must be used at the level most appropriate to enhance the priorities of safety, passenger comfort, public relations, schedule and economy.

Use of Automation
The following guidelines will assist flight crew in determining and using the
appropriate level of automation:
• Programming actions and changes to automation status should be
verbalised and acknowledged.
• Flight crew should consider that all automated systems are dumb, dutiful,
and inflexible. Pilots must continually evaluate the automatics and what
they are doing. Be prepared to make changes.
• Timely and efficient use of the appropriate level of automation will allow
other matters requiring attention to be dealt with more effectively.
• Pilots should ensure that all operating crew members are aware of the
current status of automated systems as well as any changes made to their
use.
• Should a pilot feel uncomfortable with the level or use of automation,
either more information is necessary or something is wrong. The pilot in
this situation shall ask for additional information or propose an alternative
plan.
• Flight crew should plan ahead, using the low-workload periods of flight
effectively, and avoid programming during departures and arrivals.
• The programming of autoflight systems during high workload periods
may compromise the crew’s ability to maintain situational awareness
and/or flight path control. In these circumstances, the crew should be
prepared to use a more basic mode of automation.

• Automation occasionally fails. Periodically hand-fly the aircraft to
maintain basic flying skills.


• Use of automated systems can possibly create conflict. Communication
skills assume even greater importance under automation, where
traditional forms of feedback are reduced.
• Remember, when using any level of automation, pilots always have the
capability to:
• ask the other operating crew for help
• revert to a lower level
• disengage
• reactivate.

Sciolistes 8th Jun 2011 23:52


That sounds fine to me! Am I correct in assuming that 'some hand flying' includes switching A/THR and F/D's off?
Don't knock hand flying with the FDs on. It is a great opportunity to learn to improve one's SA by making flightpath decisions thinking independantly but with the support of the AFS whilst seeing also what the AFS would preferr you to.

I see a fair few who try to recisely follow FD commands when the speed trend is opposite to what is desired, making unnecessary pitch addjustments that will obviously need corrections in sec or two, trying to follow tortuous LNAV intercepts and the like.

Depending on the type and sophistication of the FD, sometimes it is best flown when you make the bars come to you, instead of you going to the bars.

In more sophisticated ones, following the bar "blindly" is usually good enough in most circumstances.

Practice flying with FDs ON is advisable. You may one day lose AP but have FD available, along with other failures (say dual hydraulic or whatever) and if you never practice that, you won't do it as well as you could.

As for low experienced pilots, it is a good practice, to learn how to correctly fly the FD, smoothly and without rushing (not confusing a bar suddenly going fully right with a "quickly bank right" command, for instance).

If you want them to learn to look behing the bars, though, they will have to practice no FD hand flying.

Don't knock hand flying with the FDs on.
Presumably the purpose of practicing hand flying on instruments is to hone one's scan technique. Scanning involves not only the flight instruments but also navigation needles such as ADF, ILS and VOR as well as distance information.
That is exactly why single pilot IFR demands excellent instrument flying scanning skills - especially as some aircraft do not have autopilots.

On the other hand, if most of this information is fed into a flight director system, the pilots concentration centres on the flight director needles including the tiny square that forms the centre-piece of these two needles. After all, isn't the prime purpose of flight directors to make scanning easier because the one instrument will guide the pilot very accurately providing it is programmed correctly. With autothrottles thrown in as well, scanning of engine instruments becomes a secondary task to the prime task of flight director gazing.

All that being so, it is pointless to leave the flight director on if the pilot wishes to hone his scanning skills, since the whole point of the FD is to reduce scanning workload to the one instrument in the first place.

Pilots will be proficient in operating their aircraft in all levels of automation. However, the level of automation used at any specific time should be the most appropriate to reduce pilot workload during critical phases of flight, increase situational awareness, enhance safety, maintain proficiency in manual manipulation of the flight controls, maintain schedule and maximize economy. Pilots should use the available automation at the level most appropriate to achieve these objectives. In the human- machine interface, the pilot is still in charge.


My company has moved over the last couple of years from an aggressive, "use the highest level of automation" to the above statement. In my experience, hand flying, especially during departures, puts a heavy load on the PNF/PM. Everyone's SA is also reduced during hand flying. Flight during approach without flight directors, and more so A/T, really forces the PF to "stay inside" much more than otherwise. That said there is no other way to maintain hand flying skills unless you do so. :ok:


The following guidelines apply to the use of automation: • Auto flight system:
- Disengage any auto flight system which is not operating as expected.
- If autopilot engaged, PF should make all auto flight inputs.
- If autopilot disengaged, PM should make all auto flight inputs.
• Brief special automation duties and responsibilities.
• Do not allow automation tasks to interfere with outside vigilance.....
