Q

With both FCC MA lights illuminated, how are the F/Ds being operated?

A

Independently - each FCC is controlling modes for related F/D
Used during takeoff, GA and during dual approaches

  • TO mode engaged and below 400 RA
  • App mode engaged with LOC and G/S captured (CAT2/3)
  • GA mode engaged and below 400 ft RA (CAT2/3)

Q

On a go-around with the auto throttle armed, after the second push of either TO/GA switch,
the thrust levers advance to ______.

A

Full G/A N1 Limit from EEC, provided to FMC, provided to autothrottles (bucking

Q

If windshear is encountered during F/D takeoff or go around, the F/D pitch command bar
provides commands to maintain (BLANK??? )
…..
until vertical speed decreases to approximately +600 fpm..
THEN
….

A

target speed

F/D commands pitch bar to a 15 degrees nose up attitude. If VS continues to decrease, F/D continues to command a 15 degree pitch attitude until a speed of approximately stick shaker reached.

Q

What mode will the A/T be in during a V/S descent?

A

MCP SPD
Autothrottles try to maintain speed in MCP window at selected VS rate,
but its not guaranteed to hold that speed

17
Q

What does the STAB OUT OF TRIM (amber) light indicate?

A

STAB OUT OF TRIM = the autopilot is not trimming the stabilizer properly
A/P will stay engaged
