.When pilots do stupid things we may ask "WHY?" Experience showed me that most people -included not very smart or low educated pople, but very smart and high educated too! - do stupid things in command of an aircraft puting a threat on their lifes because they do not feel free because -what I'm calling- an excess of system mind. They are glued in a system they think it is mandatory to obey without using their brain.The "do-the-mission syndrom" happens when they no more understand where there own stupidity starts and where mission must be done for benefit of truth, freedom, Country defence and respect of known personal technical limits

The question is then :"who controls actually the aircraft in that letal adventure and how?"

So I first questioned statistics if they could suggest an answer.

It is an old question I had first after the Sainte Odile crash report discovering that the Air Inter A320 belonged to a Japonese society... Creative accounting has limits too. Nobody asked any question.

In another crash (Quiberon Be1900) other garbagge appeared where you ask who has the responsiility and who is the real operator whose responsibility is limited by the Warsavia/Montréal Treaty. The passenger buys a ticket to the operator not to the pilot. I found it strange too that victims went to the Court against pilots instead against these ones who contracted transport with them. If pilots did something stupid the operator not the victims should do a judicial action against pilots if they want it.

Who is Who?
You are right : don't always search another responsibility .

I don't ask more regulation, but respect of the regulation (or perhaps change it if needed by better regulation).

The most important rule to respect is : "The Captain has the decision, he must stay free"
Design, Owner, Operator have to respect that most important rule. When we list the crashes, knowing or not knowing what happened, so many times the Captain was "missing". I would be estonished if Bubbers44 should desagree.

The lawyers always go for the deep pockets. Most pilots don't have it.

roulishollandais,

what you say is not wrong, but the question WHY they crash is basically what all the accident investigations are about. And they have shifted from mere technicalities to also the stuff going on in the background.

In fact, I agree a 100% to:

The most important rule to respect is : "The Captain has the decision, he must stay free"
Design, Owner, Operator have to respect that most important rule. When we list the crashes, knowing or not knowing what happened, so many times the Captain was "missing"
And when the captain is an idiot, the F/O has to take responsibility.

In the end - IMHO - it boils down to personality of a pilot, a thing we can´t really measure (at least only to an extend) and we certainly won´t be able to get a clear opinion of what it takes to be a good pilot and a safe operation. Ask 5 pilots, get 6 opinions.
I don´t think I need 3 tonnes of manuals to fly safely, others do.

Thats just human.

Instructing Newbees and CPL needs to evaluate if you may be soloing a Newbee despite you know he cannot be already a "good" pilot but that he is able to do a safe flight, and needs to build the personnality of the CPL to be able to resist to temptation to do absurd things.
In France an Airline Instructor does not need to have these basic instruction qualifications and he can sign a type rating on the base of SOPs. The checked pilot may ignore he is not able to analyse his own actions when the flight is no more standard.

Captain/FO : redundancy and generations continuity with experience transmission.

this thread is going in circles.

Most of this has already been said and addressed several times.

The bank isn't the operator, it's simply a financing institution that holds the note to guarantee the funds are paid. The bank that holds the note doesn't have any direct responsibility over the aircraft or any operational control and probably no one from the bank has ever seen the aircraft. They just make money from interest by holding the note. The bank could care less how the plane is flown or if it flies at all. The bank probably doesn't want the plane to crash simply because they get a lump sum payout on the loan from the insurance company and can't collect any more interest...that's it.

Banks own pretty much everything. They probably own your house and your car too...even your iPhone is owned by a bank somewhere unless you paid cash without a contract....even then you only own the shell.

Actually not correct: most banks want to make sure their asset is being looked after properly, because how it is operated and maintained makes a huge difference to the resale value. We spend lots of time and effort on being audited by finance institutions, and a lot of them (certainly in Europe) will not finance a private aircraft that is not with either a management company or a company flight department they have audited .

You're still missing the point. The banks stand nothing to gain or lose by the resale value...they are simply financing the note for the purchaser. If the purchaser turns around and sells the airplane for twice what he paid he gets to pocket that and the bank just gets back the loaned amount. The bank makes the most money if you don't resell the aircraft. If the airplane plummets in value the person who bought it still has to pay the full balance back to the bank....of course he may default and the bank has to come after him and will repossess the aircraft but likely the bank has secured other collateral as well as forced the buyer to guarantee the value with an insurance policy.

Maybe it works differently in Europe but I don't think so. You're probably thinking of a different scenario where the bank may have invested heavily in the company as a whole and has financed many aircraft and other assets of the company and may even own a significant stake in the business.

The bottom line is in this case the bank will have no liability or responsibility as to the operation of this aircraft.

Gentlemen, you're getting into some pretty esoteric legal areas here, best not to go there without proper training.

The problem with discussing anything anonymously is people just have to take your word for what you know. I've said some things in these forums I wouldn't necessarily want employers to be able to identify me for...that's the whole point.

Giving away details of one's background here, while tempting, is not wise. The more diverse and specialized one's background, the more easily that the person is identified.

But you're right, it's a bit off topic to discuss the legal liability of financing companies and lien holders. One could write a book on it. Those with the most money to lose (such as banks) are highly skilled at insulating themselves from such liability.

When it comes to discussing regulations and possible implications of the accident at Aspen, that is very much on topic and has been discussed at length. I feel very strongly that unnecessary knee jerk regulations don't enhance safety rather than diminish safety.

There is no need to regulate against reckless behavior when it's already illegal. When I say illegal I mean criminally illegal. It's a crime to deliberately violate professional codes of conduct, established safety regulations or aircraft limitations when such reckless behavior results in a serious accident with loss of life and or property.

Manslaughter is already a crime, we don't need more civil regulations against it unless you're a lawyer...lawyers always want more regulation to keep them in business.

Criminal charges require a burden of proof beyond the scope of an NTSB accident investigation. Such investigations can, however, be used as evidence in both civil and criminal cases. It will take a while for the NTSB to complete it's investigation. Meanwhile, the aviation civil litigators are anxiously waiting in the "wings."

As far as criminal charges go...the fact that this captain must live his life with the knowledge of having killed his own brother is punishment enough IMO.

Article on ops into Aspen in AIN Online; it was in their weekly email summary today.

“One clear day I asked the tower if I could circle to 33 [in a Challenger] just to see what it was like,” one pilot said. “It was scary. Steep banking at high altitude introduces the potential for an accelerated stall, for one thing. It’s a risky maneuver under the best conditions in a high-performance jet.”
Which seems consistent with most of what was discussed here, namely that it can be done, but shouldn't.

I wonder how visual circling would work in a plane other than a challenger.

The lack of LEDs must up the thing by at least 20 knots.

correct me if I"m wrong, but adding 10 knots to vref protects you to 30 degrees of bank (approx).

adding 20 knots to vref almost 45 degrees of bank.

fully configured circling in a lightly loaded jet with LEDs must be about what a straight in vref in a challenger is.

I know some circling is done with only partial flaps/leds but I can see the wisdom in fully configured over the airport in a modified teardrop towards the east and coming around to 33 after reversing course over the town.

Instead of just "having a go" like this twit:

circling at Aspen would require some homework first. A couple of simple plots re turn radius would show whether it was doable or not.

No wonder people prang aeroplanes at places like that...

With a Global Express with a low landing weight...

And with a circling procedure that uses full flap (30 degrees) and Vref +10 you could be flying in the very low 120s maybe a bit lower... 122kts is a very possible target speed for circling in that aircraft.

On straight in approaches with low weights and 30 kts of wind, I have seen G/S in the low 80 kts range.

just using google satellite views, I would do a ''circle'' (VMC ONLY, DAY) as follows:

depart the airport between threshold of 15 and midfield on about a 100 degree heading, hugging the mountains to the left, starting a descent * at vref plus 20 fully configured for landing at min spoolup n1/2*

over the town itself reverse course using my best constant radius turn skills, avoiding gondolas and establish myself following the road back to the airport, by this time I would have reduced altitude and though not seeing the airport, knowing the road would take me to the threshold on an angle.


on the satellite image the road is marked as 82.



I would also remember the following, or consider the following:


if circling to 33, I would have a bit of a tailwind while starting my reversal over downtown, so this would be the steepest bank. By the time I was on a heading of about 300 or so my ground speed should be reduced by the headwind associated with a 33 landing.

Yes, there are gondolas/ski lifts, noise concerns, visual miscues from the mountains but pre planning some headings, a good copilot calling airspeed/sink rates and bank/pitch angles would help.


I would also measure the distance from the over the airport fix for the entire turn around back to the threshold and compute (by hand) the mileage and amount of altitude to lose so as to be at the threshold just above field elevation. I would plan my rate of descent accordingly. In some ways this reminds me of the expressway visual to runway 31 at KLGA. But I digress

And the first few times, indeed always, I would be ready to say OH SHIRT and go around with max power.

Don't make the mistake of pitching and banking via total visual references, use instrument/visual scan.

* descent rate calculated to reach threshold after entire maneuver just above field elevation. based on groundspeed (best guess) throughout maneuver.



* minimum engine speed for quick acceleration and not in the ''unspooled'' range, know your own engine.

So the sole survivor is allegedly getting lawyered up to sue Bombardier and the Airport....

2 x ATC fired (allegedly)...

too bad ppruners aren't on the jury.

and unless atc lied about surface winds, I think they are beyond reproach.

I wonder how the challenger would fly with LEDs?

...and what if ATC asked pilots what winds 'they needed'...? And then reported them as such? (not specifically in the accident aircraft case.)

Just a thought...


Ever heard:" what RVR do you need?" And magically 'gotten it?"

I'll correct you....

Really? protects you? from what? an accelerated stall? I don't think so!! Please don't go around flying jets with such overly simplified rules of aerodynamics in your head.

if circling to 33, I would have a bit of a tailwind while starting my reversal over downtown, so this would be the steepest bank.
Yes...this is the point where you would die if following the above rules.

life

fine, you tell me what speed would protect you and allow maneuvering at 30 and 45 degree bank, landing configuration. in terms of vref plus "X".

you select the jet.

or a series of jets.

and yes it is a simplification, and I don't have the numbers for every corporate jet? come on life, tell me. nice 'tude
