Autopilot on ground ?

Recommended Posts

The 777 incident was due to the PF selecting the A/P instead of the Auto throttle arm before take off, they nearly didn't rotate the aircraft.
The report I read said they started the takeoff roll without flipping the A/T ARM switches to on and the thrust levers didn't advance as a result when they pressed the TOGA button - the PF reached up to turn them on and inadvertently hit the AP button that's right next to them, which caused the downward trim and nearly failed rotation.
Also remember:- for the 737: don't look at the MCP for mode verification.- look at the mode annunciator on the PFD!Bert Van Bulck
This goes for any Boeing - the FMA is god.

Ryan,Simple question, without starting a Boeing/Airbus ###### discussion.Is the fact that the MCP doesn't always reflect the actual flight mode, to be called a flaw or is/was it a counscious descision of Boeing to design it this way?Bert Van Bulck
