You are joking? You are seriously suggesting that after engaging the aircraft into a 1000fpm step-climb both pilots would not even notice an engine flaming out or the A/T not moving with reducing speed?
I believe him. In fact, if one could write a book on what amazing things instructors observe during simulator training I wonder how many people would think twice about flying as passengers.

Re the above comment "You are joking". One particular scene observed recently in the sim. Crew from north Asia on DME arc leading into an ILS. Left autothrottle developed a fault while both throttles at idle in descent to initial approach altitude for ILS. Normal flap extension followed by gear down at ILS capture on AP. Right autothrottle goes up to 80 percent N1 while left autothrottle stays at idle 30 percent N1.

Control wheel well over at 45 degree angle as AP attempts to hold LLZ and captain has both feet as normal on rudders since they are not AP controlled. Neither pilot twigs there is a serious problem rapidly developing. They are automatic dependant. After a short period the instructor has no choice but to point out a problem is developing and quick action is needed. The pilots were apparently quite blind to this.

The instructor points to the offset control wheel and immediately the captain looks in alarm at the perfectly serviceable closed left throttle and calls for the engine failure checklist.

As the F/O reaches down to find the QRH, the AP gives up in despair and disengages - allowing the aircraft to yaw and roll beyond 60 degrees. The nose drops to minus 10 degrees and soon after the GPWS sounds . The captain stares at the ADI dumbfoundly but takes no action to correct the throttles or to recover from the unusual attitude. His hands are still on his knees and he makes no effort to touch the controls as the aircraft continues to roll and dive.

The F/O meanwhile is heads down trying to find section 7 of the QRH that deals with engine failure checklists. He never sees what is going on in front of him because he has orders to read the engine failure checklist. And in that culture the copilot follows the captain's orders to death if necessary.

Never mind that within the next 30 seconds both engines will fail anyway as they bury themselves in the swamp below. As the aircraft goes into an ever tightening spiral dive from 1500 feet with both pilots on another planet, the instructor saves their face (literally) by pressing the freeze button on the instructor panel.

And you think the original contributor to this particular post is joking?

These things happen in the simulator a lot more than most pilots would ever know. Thank goodness for well maintained real aircraft where pure manual handling skills in IMC are rarely called for.

There is no shortage of other similar scenes we see and these are often with very experienced captains at the controls. In every case it comes down to automatics dependancy to a stupid degree. The absence of manipulative skills is frankly bloody alarming.
