Yeah LOC is most likely IMHO. I am not as convinced as some on the CFIT narrative. Flying instruments is not that tricky given wx was anticipated, entry was at stable cruise and he had a good...

Am I correct in reading the ADS-B flight data that it took 15 seconds from level flight (Vert Speed 0 fpm) to rapid descent and losing contact.
Going half the speed would have bought some more...

In addition to the bogus flight plan would there be many other SOPs skipped or ignored? Wondering if this a/c had a CVR capacity long enough to record the pre-flight briefing, cross checks, fuel...

FBW

Overspeed vs Crazy AoA.
Surely there are too many variables to say which is preferable:
how much energy a/c has, are the engines at idle and how long until they can be safely spooled up without...

Situate, Aviate, Navigate, Communicate

TY safetypee for one of the best posts I have read in a long time. This identifies the root issue. All of these pilots knew how to fly, however they failed to understand their situation, their...

Freedom of Speech on Flightdeck

I am forced to accept the initial miscommunication "pull down".
What I cannot accept is how the FO, a french pilot would block out the grim similarity with his stick inputs to AF447. Surely FO would...

Cross cockpit comms

One thing that puzzles me is why the CAPT did not take control assertively. He is 100% responsible for a/c. Did he feel FO was more situationally aware? Perhaps another similarity with AF447 is CAPT...

NOD


You make a very good point, ultimately it is all about reducing risk. No solution is perfect. At least the sane pilot would have a fighting chance to deliver a knuckle sandwich.
