No. I fly a different aircraft but rarely is it on that quickly.

I would expect the SID to have been programmed and the pilot flying to move to proceeding to the SID path upon command. Perhaps the pilot not flying would already be working on climb checklist and handing over to AP.

No. The plane is not sentient.

Exactly what I said.

As for your speculations, a faulty autopilot is pretty much a nonevent as soon as the autopilot is off.

Perhaps instruments returned faulty readings, causing AP to be faulty. Pilots get caught off guard from faulty AP (perhaps aircraft dives for no reason), switches AP off, flies by hand and notices their instruments are faulty as well, confusion ensues.

Maybe I’m misreading but it seems like you’re implying the plane nosedived because the autopilot was turned off causing the pilots to lose control. Pretty ridiculous.

I did not say this. I said "I suspect auto-pilot wasn't cooperating due to some fault with the instruments from something like a damaged pitot tube, so the pilot decided to fly by hand."

One pilot flies while the other tries to solve problem. If it is something to do with pitot tube and elevator (which were addressed in maintenance the flight before), I would expect the pilot flying to be facing some trouble keeping the aircraft climbing, while trying to reconcile the instrument's readings and what the aircraft is doing in the hands of the pilot flying.

Nowhere did I suggest because AP suddenly turned off, causing the crash.
