QF72 the aftermath

A startling and frank account of the long term effects on a pilot, following a loss of control of QF 72 at 35,0000ft

Strongly suggest that you read the book. He did fly the plane and that's why all those people are alive.

It looks like the triple AOA inputs had one false input which the other two did not vote out, so the plane reacted. Not much the pilot could do since it was all over in a very short time. But for readers of ET and Lionair who are banking on triple or double AOA inputs solving the MCAS event, it looks like at the end of the day, no amount of automation is going to ensure a safe flight in every situation. Things can happen that nobody had anticipated or just plain go wrong. As in this case.
Here things called pilots are used. Now, if you don't train those pilots to hand- fly in RAW DATA and MANUAL CONTROL, as seems increasingly to be the case, we enter a dystopian world where if the computers cannot cope in every possible situation - clearly an impossibility, then the outcome is not good to contemplate. I believe that following ET and Lionair there is going to be a rip roaring battle between the automators and the hand flyers. It is much cheaper and easier to stuff in some more software and avoid 100 hours plus EXTRA initial training (although this cost is usually borne by the trainee) and longer Type Ratiing Courses probably involving 15 x 4 hours sessions versus the current 9 x 4 hours sessions. Then perhaps 5 full days of recurrent training per annum versus the current 3 - in some airlines 4. A day in the sim. spent doing nothing else but manual interventions and hand flying would be a good start. But then if the airline has a policy of almost banning manual flight above 400 feet as is often the case on the line, that gets us nowhere.
Oh dear here we go............Took off from Tokyo for Moscow and autopilots would not engage. At all. Flew to Moscow no problem whatsoever. But that was when Pontius was a pilot and of course nobody needs those skills these days, do they!

Happy Flying

I can almost bet you, if two ab-initio background pilots were in the cockpit, the outcome would have been very different

Not to diminish what the pilots did on QF 72 in any way - they performed brilliantly.
But they were damn lucky it happened at 35k. Had HAL decided it wanted to kill them at 10k instead of 35k, it's unlikely they could have done anything about it.
Boeing isn't the only airframer that occasionally gets it wrong...

It's reminiscent of another QF loss of control, when a B707 - I forget the model - went out of control in the cruise en route to Bahrain, late '60s/early '70s.

There were signs that while out of control the aircraft had experienced up to +3G to -3G, and may have been inverted at some point.

The reasons were quite complex, but I vividly remember the Captain saying, after we had got the passengers off and into a hotel, that he had only managed to regain control at 6,000 ft (I think it was) by using primary instruments, throttles, "stick and rudder", and doing exactly what he would have done in the Tiger Moth he had learned in.

at 10k the result would have been the same, from memory they lost less than 700 feet in the first instance, before returning to 37k, and the second incident was not as severe.

Talk about being a drama queen!

That Capt needs to remember that QF hasn't had an accident for many decades, unless you of course count that Bangkok 747 or A380 Titanic of the Skies.

Were you there? Has it ever happened to you? If not, your comment is out of order.

On what basis would you make such a derogatory remark? I happen to have flown with the Captain in the military and in the same airline, and he was a competent, unassuming pilot with a wealth of experience. The crew were presented with a flight control anomaly that was well outside of normal bounds, and got everyone on the ground in one piece. It was some time later before any rational guidance on what to do with an errant FBW system came from the OEM. The Airbus is less friendly in this case than the B777 or 787, where it is a simple matter to remove the FBW inputs and degrade to a B747.

Unless you have been confronted with a dynamic life threatening situation where you shoulder the immediate responsibility for the welfare of some hundreds of other people, I would hold your own counsel in mute ignorance.

There talks an individual who has never faced his maker. Many an aviator has gone down with PTSD following a dramatic event, I'm one, so back in your box and grow up. Thumbs up to the previous two posters.
