Automatic Flight Flashcards
From left to right, what are the three FMA mode annunciations?
Auto-throttle, Roll, Pitch.
How is control wheel steering indicated?
An amber CWS R or CWS P on the Flight Mode Annunciator
How is independent flight director operation indicated?
- Illumination of both MA
lights. - Each FCC is controlling
modes for related F/D
When do the flight directors operate independently?
- Both FD switches ON
and - during Manual flight,
and - TO/GA mode engaged and
below 400 feet RA
or
- APP mode engaged with LOC and G/S captured (occurs at GS capture).
Except for when APP modes (LOC/GS) are active. how many autopilots may be engaged at once?
One
What would cause the A/P to disengage?
- Pushing Disengage
switch (control yoke). - Control column or wheel
force override. - Pushing either TO/GA
switch with a single auto-
pilot engaged in CWS or
CMD below 2000 feet RA. - Pushing either TO/GA
switch with a single A/P
engaged in CWS or CMD
at and above 2000 feet
RA with flaps not up or
G/S engaged. - One second after
activation of stick shaker
if A/P is engaged in ALT
HOLD, VNAV PATH (in a
level segment), VNAV
PATH (flaps 15 or
greater), V/S (flaps 15
degrees or greater), or
G/S (single channel only)
modes.
o five minutes after
continuous stick
shaker if not in one of
the above modes. - Five minutes after
continuous activation of
stick shaker if the
autopilot has been re-
engaged. - Pushing either TO/GA
switch with a dual
channel auto-pilot
engaged after
touchdown. - Pushing an illuminated
A/P Engage switch. - Pushing the A/P
Disengage bar down. - Activating either trim
switch. - Moving the STAB TRIM
PRI or B/U to CUTOUT. - Either left or right IRS
system failure or FAULT
light illuminated. - Loss of electrical power
or a sensor input which
prevents proper
operation of the engaged
A/P and mode. - Loss of respective
hydraulic pressure.
When will the STAB OUT OF TRIM light illuminate?
- With the Autopilot engaged and:
o The autopilot is not trimming the stabilizer
correctly.
OR - A partial failure of an FCC. Should the failure
occur in flight, the light will illuminate on
the ground after landing when ground
speed is less than 30 knots.
What does a flashing amber A/T alert light indicate?
Indicates an A/T airspeed error where airspeed differs from commanded value by +10 knots or – 5 knots and is not approaching commanded value in flight with flaps not fully retracted.
Which system provides the N1 limit for the A/T?
The auto throttle uses FMC calculated N1 limits.
What is the auto-throttle mode when the pitch mode is V/S?
Speed mode – MCP SPD.
The bank angle selector will limit the angle of bank in which modes?
- HDG SEL
- VOR
o Use caution for test
question VOR / LOC
multiple choice option.
How is LOC and GS modes armed?
By selecting the APP button on the MCP.
When is an altitude deviation alert provided?
When deviating by 200 feet from the selected altitude.
What does THR HLD on the FMA indicate?
Indicates that power has been removed from the Auto-throttle servos.
After TO/GA is selected on a two-engine go around, the FD will command an initial pitch attitude of approximately how many degrees?
15 degree nose up until reaching programmed rate of climb.
On a go-around with the auto-throttle armed, after the first push of either TO/GA switch. the thrust levers advance to a reduced go-around N1, to produce what rate of climb?
- 1000 to 2000 feet per
minute. - Two pushes of the TO/GA
switch will produce Full
go-around N1 limit.
On a single-engine go-around, a push of either TO/GA switch will command an initial pitch of how many degrees nose up?
If single engine, the FD will command 13 degree nose up. As Climb rate increases, commands maintain a target speed.
