HF, in the EC225 pressing the go-around early will recover the aircraft from an onset UP.

Visit the AAIB website and read the report on the Blackpool Accident. These crews were flying mostly by hand in VMC conditions with a very high number of landings. The Commander was vastly experienced in doing this. Yet still they managed to get into trouble in a DVE. You re labouring under the illusion that it could not/would not happen to you if your hand skills are good enough. History proves categorically, time and time again this is a flawed argument.

Good use of automation is a very specific skill set that requires practice and procedure to increase safety and not degrade it. Given what we know of this latest accident I will be bold and say had the crew flown fully coupled it would never have happened. It is that simple.

There has never been an accident caused by loss of AP coupler or Autopilot stabilisation. Flying uncoupled is not the answer here. Flying more coupled is. If all of the above helicopters were flown fully coupled, the accidents would never have happened.

Crews fly uncoupled in DVE because they can. Do you think this option should be removed???

YOP if you really are an Olde Pilot then you would know that the term "Pilot Error" is no longer an acceptable closure to any respected AAIB report.

A lot of Swiss cheese holes have already aligned before the pilot presents his own hole to complete the chain. To prevent the accident you must break the chain. The pilot is usually just the last one in the chain.

Is this not the crux of the problem? Risk management rule #1, accept no unnecessary risk.

4 of the 5 accidents highlighted by DB had weather as a factor. Just because you can fly in crap weather doesn't mean you should; is it appropriate to operate to a deck that only the co-pilot can make the landing? Or fly when TS are forecast because your SOP says the weather forecast is in limits? On the latest accident, where was the alternate if they couldn't get into Sumburgh?

I was in the military too and, as I recall, the vast majority of flying was overland VFR. On a lot of days I regularly go flying now, I would be sitting in the crew room while I was in the military watching the weather outside.

DB, I think you have me wrong here - I am agreeing totally with you that training to use the autopilot in DVE is essential - that is exactly what we do.

But, I am also advocating that sufficient additional training is given to ensure that hand flying skills are kept polished.

We want to avoid the pilot becoming a slave to the AP; he should be confident enough to over-ride it if it malfunctions rather than letting it crash the aircraft because SOPs mandate its use at all times.

The crashes you catalogue could probably have been avoided with better use of AP modes but ultimately their hand flying techniques and skills (or lack thereof) got them into a situation where those skills ran out (the old cliff-edge of ability and task saturation).

Oh SERF - you'll find some areas of the military are required to fly in weather conditions (day or night) when no-one else is

It is distressing to see that that old Mil. VS Civ. attitude is still regrettably alive and well.
That quote is a load of b----cks. This is nothing to do with civ-mil it is to do with different philosophies. One is use the autopilot all the time and the other is to use the autopilot the majority of the time, especially in poor weather, but on nice VFR days have the opportunity to fly approaches manually to keep up one's manual flying skill set.

You are truely wedded to your idea of always using the autopilot - fair enough but my point is when it all goes past the point of the autopilot being able to recover the a/c, as in this case, what happens?

Is there any form of electrical failure that would knock the autopilot out or degrade its functions?

In the Blackpool accident I believe the Commander was the NHP - the inexperienced (377 hours were on type) copilot was HP.

No, the co was flying initially but the capt took over when he lost the plot. However, the capt failed to get the nose above the horizon and flew into the sea many seconds later, seeming more concerned with how the co was feeling than in the flight path. That suggests that all the manual flying he was used to doing gave him a feeling of great confidence which was unfortunately misplaced.

Don't these helicopters have an assigned altitude indicator that you set the MDA/DH at TOD and it barks at you when you reach that altitude, and don't they have a RADALT that you can bug that also barks at you when you arrive at the set height? I don't understand how you can descend below the minima without getting barked out, either by the instrumentation or by the NFP. And somebody must be looking outside when these things start barking at you to check if visual or not....do we know if the crew actually saw anything outside before impacting the water? Unless: I could sort-of understand if they inadvertently lost speed awareness just above the MDA and that caused things to go pear shaped very quickly with insufficient height/time to initiate recovery action.

Also for ye olde pilot, I'm not sure what world you are living in if you think that 2 pilots involved in an accident resulting in 4 fatalities, with the inquiries and court cases that is going to involve, are going to come on an Internet forum and say what happened, just to keep you happy!

I don't expect you to do my job offshore, therefore you shouldn't expect me to be doing yours.

If I knew what your job was I could perhaps comment appropriately, you perhaps assume that I am a pilot which I am not in the sense of this forum however I do fly helicopters.

A mutual appreciation of the complexity of each person's role in our industry can only be beneficial, as well as understanding that our industry needs both bus drivers and SLF to function.

Couldn't agree more and this thread has been a fantastic exchange of ideas from both aviators and offshore workers and it would be a great outcome if they are all considered when the proposed review of NS flying procedures takes place.

If your comment is meant to be humourous, sorry, once you've lost colleagues in this industry that type of humour is IMO inappropriate, especially on this thread where others are trying hard to make a change for the better.

Humorous nope, I have lost colleagues in a similar accident and can only wish,pray and work hard to ensure we all learn the lessons from them ensuring they never happen again on our watch.

I've just "googled" the abbreviation DVE - another new one since I hung up my headset! How degraded must the conditions be they officially become a "degraded visual environment?"

However, to return to the subjects on the thread: my thoughts are, if there is any doubt about "getting in", do a coupled approach. Over the sea, on a "gloupy night" qualifies, in my view, for using all the help you can get. However, if it's a few km of vis and say 500' ceiling on an ILS/localiser approach, why not hand fly whenever the conditions are reasonable.

Otherwise, how DO you keep in practice, either for a proficiency check, where I presume you still need to demonstrate hand-flying ability, or when some or all of the autopilot functions are no longer available? Crab gets it right when he says that flying is a degradable skill - use it or you will lose it!

I appreciate that this sad event off Sumburgh - to judge by the contents of this forum - seems to have been due management of the autopilot functions, rather than manual flying skills. However, it worries me that we may have a generation of pilots who are out of their "comfort zone" when manually flying.

It is a disgrace that there is not a full ILS available on runway 09 at Sumburgh, given the lousy weather factor for that airport. Also, I've just managed to find the AIP pages for Scatsta. No ILS there either.

Perhaps it would be better had Shetland remained part of Norway!!

Lingo Dan's comments reminded me - just why has the term become the more verbose "degraded visual environment" rather than just "poor visibility"? 25 letters to 14 - and that's without calling it "poor vis" as most of us use!

And absolutely, use autopilot whenever wx poor, as it was here with 2800m vis and 200/300ft cloudbase, but with two pilots, as LD says, why not one practice hand flying (some of the time) if confident cloudbase is 500ft with say 5ks + vis, with the other monitoring of course? Maybe it does happen in the NS - does it? Is is permitted even?

We have to get back to reality here. Assuming this was another CFIT (which seems most likely) it is another clear case not of poor hand flying skills but of poor use of automation. All of the CFIT accidents in the NS in the last few years would have been avoided completely if the automation had been used properly. That is fact. We are barking entirely up the wrong tree if we think the answer is to train people to hand fly better. We MUST be teaching people to fly the coupler and use the automation better. My experience from sitting in the back of the sim is that very often people are just not using the automation properly and to its full potential, resulting in the worst form of flying - neither fully coupled nor fully manual. I find that almost all pilots fly without problem when fully decoupled. We train all to fly AFCS off precision and non precision approaches, (usually OEI or with other malfunctions.) It is very rare that they cannot do this and almost always fly without problem to minima, very often with a missed approach as well! We train this in every OPC/LPC. Where we almost always see problems is when people get coupler confusion. This is invariably due to partial coupling followed by distraction and stress. Lack of good and thorough understanding of the coupler/AP increases their stress. Those who suffer this are invariably those who blindly refuse to use it properly or practice using it properly during normal line flying.
The modern day automation is a fantastic step forward and undoubtedly the greatest aid to safety in the offshore environment. The problem is those who insist on not using it properly and fail to embrace it fully.
I too remember my days of flying without any autopilot at all and only basic AFCS in all sorts of shittiness, and it was occasionally bloody scary. No need for it these days. The AP and AFCS is a no-go item for a reason.
DB - you beat me to it with the stats! Al-Bert you memory is clearly fading and the rose tinted glasses are getting steamy! You know as well as I that the RAF has had more than its fair share of CFIT. Go further and compare the number of flying hours flown in the NS vs the RAF per year and the CFIT stats are relatively low in the NS. I knew several RAF CFIT stats personally. Your glorious career of under 200 hrs per year is all well and good, but i know people who have flown an average of over 600 hrs per year for over 30 years amassing over 20,000hrs in the NS and they have never ended up in the water either!
The reality is that we need to go further with automation and develop better SOPs and software modes and embrace it fully. We can and do still maintain hand flying skills, but we should not do that to the detriment of using the safety devices we are being provided with.

Brian Abraham:
From the excerpt you posted from AAIB issued information, one will ask one's self:
were the pilots flying the aircraft or was the aircraft flying the pilots? (See the points on "over reliance on automation" rather than YOP's vague "pilot error" depending upon the answer to that question.
IF, and this is a big IF, the crew were doing a form of automatic approach, at what point did the crew realize "it's gone wrong" and try to salvage it? Hopefully, a more complete report will clear that up, or show that this supposition is incorrect.
crab:
We want to avoid the pilot becoming a slave to the AP; he should be confident enough to over-ride it if it malfunctions rather than letting it crash the aircraft because SOPs mandate its use at all times
Will management listen to such talk?

Those who suffer this are invariably those who blindly refuse to use it properly or practice using it properly during normal line flying.
This is not a new problem. I'll set aside the issue of "using the systems properly" as that is its own subject. I'll address the distraction piece.

Anecdote: some gents I knew, a bit over 20 years ago, skipped an SH-60B off of the surface of the ocean (fractions of a second away from a crash when one of the crew bellowed for power) as they settled toward the water, coupled at night during a low approach (SAR training exercise, IIRC) both a bit too interested in the tactical display and the PF not quite attentive to the bottom falling out from under the aircraft. The aircraft was damaged, and often referred to afterwards as "Skippy" by people in the know. It did not end up at the bottom of the sea, but could have easily enough.

A few other crews over the years did something similar, but didn't catch it in time and put aircraft into the water due to distraction from the flying task. Clear roles in PF duties and priority, and PNF duties and priority, were a topic of a lot of squadron briefings and sim period emphasis, yet still stuff like that happened. In our wing, one of the better intitiatives was the empowerment of the aircrew in the back (systems/radar operators, SAR swimmers when demanded) too more actively yell for power or call altitude during particular evolutions. Saved no few cockpit crews from type of dog up, that did, over the years.

Question for NS operators: is there a "sterile cockpit" period in NS pax flights similar to the "sterile cockpit" standards for fixed wing airline flying?

Sterile cockpit

Yes, certainly in Bristow anyway. However one has to be careful with such concepts. The Ops Man A has had the concept for sterile cockpit for a while. It started out as being in place for takeoff, approach and landing. Then there were some issues with misunderstood departure clearances, so the whole taxi phase was included which in Aberdeen can last 20 mins or so. Then as a result of ATC's fatuous obsession with alt busts being the most evil thing in aviation, the whole climb to cruising level, and descent from cruising level, was included. Thus on a 225 which might be cruising at say FL70, that means the first perhaps 30 mins, and the last say 30 mins (descend from FL70 at 500'/min, an instrument approach, taxy back), plus somewhat less for the offshore arrival and departure, and you end up with a good chunk of the flight sterile cockpit - supposedly! So by overdoing it, the whole thing becomes devalued.

Unfortunately these sort of creeping changes are often done in response to external pressure, rather than as part of any joined-up thinking.

I don't know why I'm bothering to respond to you 26500 but my annual reports always said 'this officer doesn't suffer fools gladly' so here goes:

true, we didn't fly 600 hours per annum, of hands off straight lines to a rig. Nor did I ever fly less than '200 hours a year' or 300 for that matter. What I did fly, on top of six years SH was 22 years of SAR - and yes, the Seaking AFCS saw lots of use. If you regard a 2-300 cloud base and 2.8k's vis as poor weather then you have never been where I've been. Lets hope that you don't ever try for the CivSar contract too. Nor have you read what I have been trying to say in my posts on here - but, carry on, you're all doing very well!

Lonewolf,

At least one operator does (2 now I've seen Bristow do as well), I would imagine they all do. HC's points are very valid though, very few crews will sit in almost complete silence for the 15 mins or so it takes to come down from from a flight level, or at the Holding Point at 0715 when ATC tell you you're number 10 in the queue!

26500lbs,

Please remember when comparing military to civil CFIT per fg hour figures that the vast majority of the military fg hours will have been done within a few hundred feet of the surface, as opposed to a few thousand feet in the cruise in the NS. Not disputing your overall point, but in this context NS hours vs mil hrs are vastly different beasts.

A question for the NS operators:

How thorough is your AP training? Do you cover such things as AP degredations (of which there are many and not always obvious) and practise them? Do you show your pilots the gotchas?

I am sure many of your new hires will have come through the standard PPL/CPL/IR route of training. None of those courses teaches use of autopilot, or didn't when I did my IR - do any "simple" twins used for initial IR's (AS355, A109, EC135) have 4 axis autopilots?

Many other new hires will be coming out of the military - again, do they come from a background familiar with sophisticated autopilots?

All of those above will have considerable training of single engine rejects and hand flown approaches, but little to no autopilot handling experience.

Where is the emphasis during conversion training with Bristow, Bond and CHC (+ NHV, Dancopter etc)?

My knowledge of the autopilot on my primary aircraft type was picked up "on the hoof" with no formal training that I can recall at all - despite type rating training with a very well regarded 3rd party provider (in level D sim). The "on the hoof" training was not done by the Company TRI/E but provided by other company line pilots while flying the line and each had a slightly different way of doing things (such as AS vs VS hold on 3 axis approaches)
Incidentally, use of the nav system was also only touched upon - basically the training generally went over the stuff that was the same or very similar to every other helicopter I'd ever flown, and barely touched on the bits which were genuinely new to me! I'm not suggesting that NS training is like that, but would be interested to hear.

OBF you make your point well, military flying is a vastly different beast to Offshore Crew Change Flights. However, it does not stop the sanctimonious SAR fraternity from believing they understand our job.

I welcome any ideas from anyone. However, being told we should fix the problem by "More Hand Flying" is a bit like dunking a witch.

Albert - please explain how you managed to "hand fly" SAR missions in weather less than 300 feet and 1800m. If you can then please explain how you would feel about me doing the same, leaving the DAFCS coupled functions in their box, with your family sat behind me in the PAX seats. Or how about you behind me!!

You talk two languages Sir, "Utter Sh*te" and "Total Boll*cks"

26500 lbs. Great post!!

So did mine funnily enough - so we have something in common, but I do not know what that has to do with this discussion.

I am not quite sure what your weather reference and CivSar references are about other than condescension, which is unnecessary. I can assure you I am quite aware of what bad weather is! I do know why I am bothering to respond to you Al-Bert. I do not think you are a fool, but I do not think you are seeing the whole picture. I have flown both sides of the military/civil divide, and believe there is a balanced argument and discussion to be had, rather than trying to outdo each other with our CVs. I hear what you are saying loud and clear, although they way articulate it is not always so clear. I do not disagree with your sentiments. However the situation is more complex in that a civil operation is filled with issues the military operation is not. Training is far more limited due to the nature of budgets and how much the customer is willing to pay. There is always a competitor who will try and do it cheaper, driving competition and stretching budgets ever further. My point is that we have what we have and have to work with that and within some of the constraints we have upon us. That is nothing new to any of is, and we had the same issues in the military world. Maybe we can relieve and adjust some of the constraints but the reality is we are not going to get a new unlimited training budget across the NS. We can do the job better. We have to move forward and discussion such as this will only help that.
It is just no good trying to fly a modern day operation in the NS with modern tech in the same way we ran a JHC operation. The people are different. They have different backgrounds. The culture is different. The operation is a different challenge. The challenge of routine is one in itself I never really understood until I did it. These days my challenge is keeping pilots motivated and engaged. The routine all too often creates a complacency in a different way to what we used to see when flying complex military tasks in NI or Iraq or Bosnia or Afghan or any number of other demanding theatres. The NS is no less demanding, despite what some may believe. The demands are different and often not always so obvious.
Routine operations are inherently linked to human error. Why do we have robots building cars? We make mistakes all the time, but the latent errors in routine often go unchecked until its too late.
All a bit longwinded I know, but we have to take a fresh approach to how we tackle very routine operations. The proper and appropriate use of autopilot is key to this, and development of appropriate SOPs will lead to a reduction and management of latent error. Better training in the sim and classroom will help us when it is not routine. This is being done in some places already, so nothng new. It does not need to cost any more either, just needs to be better planned and controlled. Better selection of crews and management by companies will also go a long way. However the recent lack of pilots meant very low time pilots being hired, who have effectively no experience outside the circuit. This is just a fact, and has already happened. Do we kick them all out and hire a bunch of experienced pilots? A little facetious, I know, but of course we have to use them. We can train them, but companies must take this into consideration when they hire. The problem of the inexperienced pilot will not be seen for 10 years, until he is a captain.
What we cannot do is the halfway house approach we are sitting in right now.
