NTSB says Delta Pilot Error
 
NTSB blames pilot error for Delta plane that skidded off snowy LaGuardia Airport runway | abc7ny.com

Passengers were told to exit over the broken right wing because the door out the back was too close to the water.
I could have sworn the pointy bit was at the front.

How can two crews report "good" braking, then this?

Jet Jockey A4 14th Sep 2016 12:56

I'd like to know what type of aircraft reported the "good braking".

Also looking at that short video, it seems there is a lot of snow on the ground.

The application of excessive reverse thrust during a landing at LaGuardia Airport, New York, March, 5, 2015, led to a loss of directional control and the passenger jet’s departure from the snow covered runway, according to findings of the National Transportation Safety Board

There is another topic on Prune where it is mentioned that in 1 EU major airline, of which a good mate of mine is a captain and has, as yet, had no problems with their SOP, where PM selects Reverse Thrust. I wonder what the debate would be in the event of such an accident in their fleet.

RAT 5 14th Sep 2016 19:18

Just a point of information. At my employer, PF does NOT operate reversers! That is a job for PM. That simple fact allows me to pre-brief that PF does not remove their hand from the thrust levers unless they are happy we can stop, AND PM does not select reverse unless they are also happy we can safely stop. Either pilot can call go-around. We both have a very immediate investment, and clear responsibility, in the landing! ONLY when reverse is selected, are we committed to completing the landing! Not before.

Reminds me of that wacko 'monitored approach' some carriers were using a while back for low viz operations. One pilot would fly the plane to minimums and then hand over control to the other pilot to do the landing. :eek:

Sounds like an urban legend but I think it was actually an operational fad at one time, kinda like not using reverse to save the engines. Steel brakes versus carbon brakes or something like that. I realize that you still can't use above idle reverse with some noise curfews.

American Airlines was famous in years past for doing things their own way. At one time their boarding doors were on the other side of the aircraft and they still used QFE long after it was abandoned by other U.S. carriers. I'm told that the PM still guards the throttles after V1 on takeoff because of an engine rollback years ago. Or is someone pulling my leg on this one? :confused:

Anyway, at Delta I'm guessing that the pilot flying handles the throttles and reversers on landing. And going off the end at LGA is unfortunately a time-honored tradition, seems like USAir did it twice on takeoff three years apart.

This widely-circulated item from the 1990's is probably parody but after reading some recent flight ops bulletins, I'm not so sure:


*** British Airways Flight Operations Department Notice ***

There appears to be some confusion over the new pilot role titles. This notice will hopefully clear up any misunderstandings.

The titles P1, P2 and Co-Pilot will now cease to have any meaning, within the BA operations manuals. They are to be replaced by Handling Pilot, Non-handling Pilot, Handling Landing Pilot, Non-Handling Landing Pilot, Handling Non-Landing Pilot, and Non Handling Non-Landing Pilot.

The Landing Pilot, is initially the Handling Pilot and will handle the take-off and landing except in role reversal when he is the Non-Handling Pilot for taxi until the Handling Non-Landing Pilot, hands the Handling to the Landing Pilot at eighty knots.

The Non-Landing (Non-Handling, since the Landing Pilot is Handling) Pilot reads the checklist to the Handling Pilot until after the Before Descent Checklist completion, when the Handling Landing Pilot hands the handling to the Non-Handling Non-Landing Pilot who then becomes the Handling Non-Landing Pilot.

The Landing Pilot is the Non-Handling Pilot until the "decision altitude" call, when the Handling Non-Landing Pilot hands the handling to the Non-Handling Landing Pilot, unless the latter calls "go-around", in which case the Handling Non-Landing Pilot, continues Handling and the Non-Handling Landing Pilot continues non-handling until the next call of "land" or "go-around", as appropriate.

In view of the recent confusion over these rules, it was deemed necessary to restate them clearly.

That's still SOP for many carriers, I believe (in Europe, and U.S. regionals). Monitored approaches isn't inherently good/bad; there's pros and cons to everything.

Waiting in Idlewild - yes, Idlewild - Customs hall one day, a Pan Am ( Ahh ! ) Captain approached my Captain and asked if "You's guys did that monitored approach stuff ?" ( BEA, the airline that was experimenting with monitored approach was the other airline that merged with BOAC to form the present British Airways

My Captain said No. Well, said the Clipper Skipper, PanAm has used the monitored approach system since day one. Really ? we replied. Yes, said the Clipper Skipper, pointing to his First Officer - I fly, he monitors.

QED.

Vessbot 15th Sep 2016 01:03

I'm at a regional in the US and use the monitored approach for Cat II ILS. Autopilot mandatory, FO acts as PF until he calls Minimums at which point the Captain takes control and lands if he sees the runway. (I say CA and FO because the roles are not reversible for Cat II)

I didn't know how to feel about this when I first learned about it and was a bit skeptical of the last-minute monkey motion, but I see the rationale, which is that the Captain has more reaction time once going visual if he's already outside looking for the runway, than he would if transitioning from instruments to outside.

neville_nobody 15th Sep 2016 02:32

I think a fairer outcome would be 'the Captain failed to sufficiently compensate for a poor aircraft design whilst under high cognitive work load.'

PEI_3721 15th Sep 2016 09:43

Is this accident indicative of the US system?
The crew appeared to be under some HF pressure, a desire to land. And even with some doubt about landing performance the approach was continued. "If there is doubt, ... then there is no doubt, don't do it."

The crew had poor information about the runway condition and braking action; yet the FAA has issued endless guidance (ACs) after TALPA on how and what to report, the role (and danger) of PIREPS, and for the industry to reconsider landing performance.

Has anything changed?
Dependence on PIREPS, dependance on reverse thrust, friction measurement (not universally accepted as accurate), and the use of 'actual' landing performance - with minimum additional factors (was this Boeing or third party data?).
Assuming that the landing performance included credit for reverse, was this using max reverse or the recommended lower value to be used on a contaminated runway?

Herod 15th Sep 2016 14:01

Both my last two companies used the monitored approach technique for all low-vis ops. The FO flew the approach/monitored the A/P, up until DH, at which point the captain, who has been looking out as well as monitoring the FO/AP combination, takes over for landing. Makes a lot of sense, since the captain has an easier job transitioning to the visual at a critical moment.

slast 15th Sep 2016 14:25

Fake "BA monitored approach" notice
 
The so-called "British Airways Flight Operations Department Notice" is a fabrication from the mid 1970s created by a BOAC pilot, who circulated it in a slightly different format as part of an unsuccessful campaign against the merger of BOAC, BEA and several other smaller carriers into British Airways. I have all the original files from that period.

Rather than "wacko", a balanced and more comprehensive description can be found on the respected Eurocontrol / ICAO / Flight Safety Foundation Skybrary site, Monitored Approach - SKYbrary Aviation Safety.

The NTSB said in a 2000 accident report that "the monitored approach method provides for more effective monitoring by the non-flying pilot because captains are more likely to be comfortable offering corrections or challenges to first officers than the reverse situation. ............ Monitored approaches decrease the workload of the flying pilot and increase flight crew interaction, especially when experienced captains monitor and prompt first officers during the execution of approaches."

It's also likely that for example UPS 1354 pilots Capt. Cerea Beal and F/O Shanda Fanning would still be alive if they had been using this procedure. It is specifically designed to protect against many of the contributory factors in that accident, particularly having both pilots "head-up" seeking visual cues as the aircraft approaches DH. This weakness in traditional procedures was recognised in NTSB studies going back as far as 1976. There's much more about these issues on the picma.org.uk website.

However, can I suggest that since the IFR approach procedures used probably did not greatly affect this particular accident, this thread would benefit from concentrating on the issues of contaminated runways, braking action reporting, and aircraft design/handling issues that were actually involved?

Capt landing in low vis sounds like an insurance thing.

The same notice was 're-issued' by some joker in the late 1990s. At that time, the 747 Classic fleet was the only remaining* BA unit that didn't routinely fly monitored approaches. (I think they did for weather worse than Cat1 *and I don't know about CCDE.) When the Classic fleet did eventually 'catch up', someone posted the notice as a tongue-in-cheek riposte.

Having flown for different airlines and experienced both approach methods, I would agree with most of the others that the monitored approach unloads the Landing Pilot and informs him/her at an earlier stage as to the likelihood of a landing or go-around. The other crew member will be locked on to the instruments and will perform a go-around if there is no clear communication or any ambiguity at minima.

As far as reverse thrust lever handling is concerned, giving control of the TRs to the PM enables the Landing Pilot to concentrate on steering and braking. The PM will monitor the Speedbrake/Spoiler and TR deployment, N1/EPR, and give the PF the amount of reverse required. He/she will also monitor autobrake disconnection and call the speeds. That list shows that the PF is relieved of quite a few duties and can look outside all of the time. The PF can also ask for 'reverse idle' or 'forward idle' if any steering difficulties arise. The same SOP is used for an RTO.

Having said all that, my understanding is that the BA A380 fleet is about to change the SOP and have the PF operate the TRs!

I see the benefit of a monitored approach in dodgy weather, but I think it'd be quite a pain in the rear to do every approach that way.

As to the PM using the thrust reversers...:rolleyes:

Does the PM also control thrust on approach?

Pontius 21st Sep 2016 05:43

It's not a pain in the rear at all. Hand over control just before TOD, take over control either around 1000' when visual and all is stable or at minimums (if applicable). It's really very, very easy and takes just a few minutes to get used to. I much prefer it to the 'whole sector'-type flight that you're used to. Horses, courses etc etc.


As to the PM using the thrust reversers...
Why the stupid emoticon? The procedure works very well and it does offload the PF, who can concentrate on doing other things is strong crosswinds etc. Just because the PF is no longer an all-conquering hero who single-handedly fought the bucking beast onto the runway does not mean the procedure is flawed. You brief what you want, if you want more or less you just say. It's not rocket science, it works very well and has advantages over the PF using the TRs. In fact, I'm hard pressed to think of any reason why the PF needs to handle the TRs apart from that's the way they did it on the 707 and we can't possibly use our intelligence to imagine a more effective use of resources. The Captain is no longer a one-man band who has to do everything........unless he's a control freak.

No need to be facetious just because it's not the way you do things.

startall4 21st Sep 2016 07:12

I wonder how often, if PF is selecting reverse, the reverse selection is "fumbled" because the PF "misses" the reverser levers because he is (hopefully) looking out the window.
Also on a type (like wot I fly), where reverse is available and normally used on all four engines, and, say, one reverser doesn't unlock, that certainly would be less of a distraction to the PF if the the PM is selecting reverse.
In my airline PM selects reverse.

However do military fighter pilots cope with 200 ft decision heights when flying single seat jets....:confused:

Perhaps because they don't have any of this headshrinker horse$hit to worry about and are fully capable of 'going visual' after an IMC approach?

No such thing as pilot error. All accidents are a function of human error in numerous ways _ training, instructors, manuals, weather conditions etc etc.

Entirely different sort of operation however, as I said before: 'JDI!'

Point taken, but if the CA does the approach until all is stable, when does a new FO (or CA) on type get to learn from his mistakes? Getting burned is part of the learning process, and if you get the plane handed to you on a silver platter, so to speak, when do you learn how NOT to set up for an approach, and how to fix it when you've done it incorrectly?


No need to be facetious just because it's not the way you do things.
I'm not being facetious (ok, maybe just a little), but it's a serious question. On my type, to select reverse, I slide my hand forward a bit and pull back. That requires far fewer brain cells than managing thrust in flight, particularly on a windy approach.

If managing thrust is so difficult during the rollout, it should follow that the PM should manage the thrust while in flight, so the PF can concentrate on doing other things. That seems to be the logical extension to that line of reasoning.

PS. You're absolutely right- the whole thing seems foreign to me, as I've never heard of that procedure before. From the outside, it seems like an unnecessarily complicated procedure.

Basil 21st Sep 2016 13:41

I was FO on an aircraft following a very big merger.
We operated the monitored approach system. My captain came from a company where they did not.
C: "D'you mind if I fly my own approach?"
FO: (In warning tone) "Well, YOU'RE the Captain."
FO: (on short finals) "YOU'RE HIGH AND FAST ON A SHORT WET RUNWAY!"

Despite warning, Capt lands and bursts all maingear tyres. I thought we were going off the end.
Funny old thing; I never heard another word about it.

JFDI!

Normally if the captain was PF on the first sector then the FO would do the approach for the captain's landing. On the next sector (all things being equal, weather etc) the FO would be the PF and the captain would do the approach for the FO's landing. The nice thing about this procedure is you get to have a 'play' on every sector and the FO's still get to practice all the things they'd practice in a non-'monitored' approach i.e. they still get to learn from their mistakes.


If managing thrust is so difficult during the rollout
I don't think anyone is suggesting it's difficult but there may be better ways of using the two pairs of hands available, rather than just one pair doing everything. It was certainly 'different' when I first came across this procedure but it is easy to get used to very quickly and I found I had more capacity to better manage other dynamic events with the help of the guy/guyess in the other seat.


However do military fighter pilots cope with 200 ft decision heights when flying single seat jets....

Perhaps because they don't have any of this headshrinker horse$hit to worry about and are fully capable of 'going visual' after an IMC approach?
Ahh, the dinosaur arrives. Having done both I can assure you that the colleagues with whom I fly are just as capable of 'going visual' after an IMC as I was when I flew single-seat fighter jets. They have to contend with other issues that are not applicable to nimble, agile fighter aircraft and yet they seem to get it done really quite satisfactorily. The fact that you refer to effective management of crew resources as "headshrinker horse$hit" is ample indication of your luddite and old-fashioned views which have little place in modern aviation.

Fair enough. On the west coast of the Atlantic, the prevailing theory is "your leg, your controls"- up to and including the next approach after you've messed up the first one. Obviously, the PM is will speak up if he's not comfortable, but it's not atypical for a CA to sit back and watch the FO mess up (within reason), and use it as a teaching moment.

Bloggs, I know of at least two 747 runway excursions when the pilot only grabbed three T/R levers, then managed to nudge the fourth throttle forward while working the T/R levers. Both resulted in the 747 doing basically a 270 deg spin as it left the runway :eek:.
Fortunately, no serious damage or injuries resulted, although I suspect there were some soiled undergarments :uhoh:

Holy cr@p! :ouch: What does the manufacturer recommend re use of the reversers?

tdracer 22nd Sep 2016 00:21

To the best of my knowledge, Boeing does not recommend someone other than the PF working the throttles. I know that whenever I've been on the flight deck for landing during flight testing, the PF always works the throttles and T/Rs.
I was just pointing out the concept of someone else doing it isn't completely crazy...

exeng 22nd Sep 2016 00:25

All quite easy really,

The PM selects reverse as soon as main wheel touch down. The PF then continues or cancels reverse if directional control becomes an issue.

The introduction of this SOP caused a few initial problems when I was flying for Big Airways, (like nobody selected reverse at all !!!) but then everybody settled down to it.

Observing from the car park adjacent to 26L at LGW it was always the Big Airways planes that had reverse selected before the 'others'.

Leaving Big I flew for two other operators who both insisted the PF pulled reverse. (one of these a large West African carrier). Handling a landing in a xwind on a wet and poorly drained runway meant I was a couple of seconds late with reverse.

exeng 22nd Sep 2016 00:48

And another thing!
 
I did not like the introduction of monitored approaches in Big. For low vis it was correct and was trained for every six months. For all ops - quite bonkers in my opinion. Good vis in howling winds and I fly the aircraft to about 500 ft where the F/O takes over to land - well it may not have the best possible outcome will it - some F/O's or Captains will do well and some won't.
