TAMS is always at least 10 knots greater than minimum control speed
When is the takeoff configuration warning armed? (5)
Airplane is on the ground
FUEL CONTROL switches in RUN
Either engine thrust in takeoff range
The thrust reversers not unlocked or deployed

Entry, fwd or aft cargo not latched and locked
Leading edge/trailing edge not in takeoff position
Parking brake set
Rudder trim not centered
Speedbrake lever not DOWN
Stab not in green band
Can you silence a takeoff CONFIG warning?
No.
The WARNING lights can be reset, but it does not silence the warning or clear the EICAS message
Only way to silence the warning is to reduce thrust
CONFIG message will remain displayed for _______ ________ after reducing thrust
CONFIG message will remain displayed for 10 seconds after reducing thrust
When is the CONFIG GEAR displayed?
Airplane is in flight
Any landing gear is not down and locked, with either thrust lever closed and RA less than 800 feet, or FLAP lever in the landing position
Can the CONFIG GEAR be canceled?
Yes, provided the message was because the thrust lever were closed at low RA
If the message was due to the flaps being in the landing position, the warning alert cannot be silenced except by the gear down and locked, or GEAR OVRD selected on the GPWS page of the TCP
