To my post:
One of the last ACARS Messages transmitted by AF447 concerned cabin pressure, IIRC external altitude becoming lower than cabin altitude.
It makes me sick thinking about it:
- Turn off ACARS
- Then depressurize
- Wait 12 minutes until cabin emergency O2 is used up
- Turn off transponder
- Zoom climb to what is possible, on topping out there will be less than 1g so it can be somewhat higher than what is in the spec
- now return, over land no cell phone calls will be made
To the psychological aspect:
- Maybe the initial plan was to hit the petronas towers.
- The above maneuvre is physicaly extremly challenging. Going "semi-ballistic" in a depressurized cabin on o2 only.
- After recovery you might see things differently and refrain from original plan=> erratic flightpath.
- You are now in a psychological challenging environment with harm done to every soul on board.
- There is no way to fix this situation, but you don't want to cause any more harm any longer.
- Program FMS to go above the Malaca Strait into the Indian Ocean an then set a last waypoint, the obvious one would be 90 degrees south.
- Now depressurize again, don't put your o2 mask and doze away.
The aircraft or what remains of it would be found south of where longitude ~95°E intersects with the southern branch of the "ping arc".
