Lyman / HarryMann

I am not the right person to comment, having not been in a real high altitude aerodynamic stall since 1967 (not a passenger airliner, I hasten to add!), but stall recovery should never be considered...

(1) The key words were "this crew", in the context of the CRM issues that have arisen. It is much easier to avoid an aerodynamic stall, than to recover from a FLT100 per minute plunge.

The key issue was to avoid the stall, after the A/P and A/T disconnection.

But there was still plenty of height to play with in which to recover from this aerodynamic stall, if...

When the computer computes "I do not compute", as it did on AF447 (due to UAS data), you should always have the underlying airmanship upon which to fall back on...

There are one or two clues...

I think the history is the key - AB was developing in the context of 1985, a truly horrid year for the aviation history e.g. Boeing had lost several 747s, part of the US 101 Airborne Div...

Yes, good way of putting it - flip sides of a coin (implied automation savings, separate/additional to conversion costs across the later range of Airbus aircraft).

I accept your good point re: conversion across a range of aircraft, but I recall that my airline (when it spoke with AB before retiring its BAC1-11s) clearly was left with the impression that less...

Helpful and thought provoking post.

The only word of caution that I would add is that we must be very careful before separating "automation" and "training" - the former implies new skills in...

It's just the most tantalising limited-release CVR comment, at FLT200. The reality is that the BEA, even with access to the full FDR/CVR, may never know what the CDB meant by that remark (and the...

Yes and no.

Not easy, not by any means, but troubling that they did not appear to diagnose the stall to the very end (unless you interpret the CDB's "impossible" remark). There were plenty of...

Quite - hence my unease at the entire SS concept (#1535)

Affirmative. It also explains why F/O 32 was the obvious choice to carry on as the PF and become the relief pilot (given the pre-AF447 position as set out by takata).

Thanks for clarification re: the long layover (long enough for F/O 32's wife to holiday). Don't like using (deceased) pilots names, but sometimes it just causes less confusion in the end.

Yes, save for your final sentence under (4). This was not the same crew that had flown out, if my memory serves me well (e.g. PF had been on holiday with his wife, without their children, on board...

CDB even had to check, when he switched with the dozing F/O 37, that F/O 32 was qualified to implicitly take command as the PF (and had been the PF from GIG). Given my vintage, don't even get me...

You were correct first time. F/O 32 was PF in the RHS throughout. F/O 37 replaced the CPT in the LHS. F/O 37 had been resting (dozing) until not that long before the incident, which may partly...

Good post. You have to embrace new technology, but build on the basics of the past. Buying a satnav for your car doesn't justify no longer being able to read a road atlas, just in case, if we are...
