AFCS Flashcards
What is the bank limit when BANK is selected
17 degrees used by the heading button
What does the amber LIM on the FMA indicate
LIMIT is displayed to indicate that the vertical speed and target speed are incompatible with thrust
How many auto pilots on the E-175
Single auto pilot with dual channels. One is active, the other a hot spare.
Will the auto pilot disconnect when FBW reverts to Direct Mode?
Yes
Will the auto pilot disconnect if the aileron or elevator disconnect handles are pulled?
YES
What happens if the pilot applies force opposite of the auto pilot input?
The AP will disconnect under a long term light force and a short term stronger force
Will the auto pilot disconnect when Windshear escape guidance is activated?
YES
If the stick shaker is activated, what happens to the auto pilot?
It will disengage
When is the yaw damper engaged?
Automatically after power up of either HYD 1 or 3
What hydraulic system is the yaw damper system on?
Hydraulic System 1 and 3
What FMA modes are present lining up on the runway for takeoff?
White TO for the auto throttles armed
Green ROLL for LNAV
Green TO for VNAV
In ROLL mode when does the autopilot return to wings level?
When bank angle is 6 degrees or less
In ROLL mode when does the auto pilot hold the present bank angle?
Between 6 and 35 degrees
What altitude will LNAV engage when armed on the ground?
200 ft
LNAV can be engaged above what altitude?
200 ft
TRACK occurs on takeoff when?
When IAS is greater than 100 kts
and
Bank angle is below 3 degrees for more than 10 seconds
The FD commands a pitch up of ___ on takeoff
V2 + 10
Explain the GA mode pitch logic
GA first sets pitch to 8 degrees
If speed is above pitches to speed target
All engines operating: Vref +20
Single engine: Vac (approach climb)
Windshear escape guidance is active below what altitude?
1500 ft
When WSHR becomes active is the pilot required to disconnect the auto pilot?
The autopilot automatically disengages when WSHR is active
HOLD mode is active on takeoff when?
HOLD becomes active at 60 Kts and remains active until reaching 400 ft agl
What does HOLD mode accomplish
De energizes the auto throttles
When does RETARD mode activate?
30 ft agl
