Auto Flight Flashcards
(32 cards)
What systems make up the Automatic Flight Control System (AFCS)
1) The flight director (FD)
2) Autopilot (AP)
3) Auto-throttles (AT)
Which panel hosts the controls for the AP, AT and FD, plus lateral and vertical reference/ mode selection
The Automatic Flight Control System Panel
What does pushing the FD button on the AFCS panel do?
Engages and disengages the flight director on those PFDs
What does pushing the AT button on the AFCS panel do
Engages and disengages the Auto-throttle
Selects the source of the speed reference between MAN and FMS
What does pushing the HDG button on the AFCS panel do
Selects heading mode when pushed once and roll mode when pushed again.
Pushing the BANK button on the AFCS will toggle between what bank angles
+- 15 deg and +- 30 deg
What is the up and down range of the FPA mode
9.9 deg up and down
How can the flight patch angle/ reference line be selected?
By rotating the FPA knob
What does the outer knob of the ALT knob select? The inner knob?
1) Outer - Selects the altitude increasing/decreasing 1000 feet.
2) Inner - Selects altitude increasing/ decreasing 100 feet
What does pushing SRC button do
Alternates between PFD 1 and PFD FMA modes as the source for the auto pilot
When the autopilot is engaged, what does pushing the TCS button on the sidestick do
It activates the TCS (AP override) as long as neither the takeoff or go around mode is active.
Where are the AT/DISC buttons located? The TO/GA buttons
On the Thrust levers
With the AP engaged, will the AP disengage if the force is applied on the sidestick, either in the pitch or roll direction.
Yes
What are the two FD cues presented?
The flight director cue (magenta circle) and the takeoff cross bar.
What does the green Flight Patch Vector cue indicate?
The current flight patch in reference to the horizon line.
Where is the Flight Mode Annunciator (FMA) located and what does it display
On the upper part of both PFD’s and it provides annunciation for auto throttle, autopilot, approach status, lateral and vertical modes.
List the FMA color codes for normal operation
1) Magenta - For FMS active/ engaged modes
2) Green - Non- FMS active/ engaged modes
3) White - Armed modes
4) Red - Abnormal condition.
What does the amber LIM on the FMA indicate
The autothrottle is in speed mode and the selected speed mode and the selected speed target cannot be achieved because the auto throttle has limited N1
What are the two precision approach capabilities of the airplane
Either APPR 1 or APPR 2
When is the AP aural alert triggered
When the AP is disengaged due to a system failure
How can the AP aural alert be cancelled.
By pressing the AP/PTY buttons on either side stick
When will the airplane automatically transition to the half bank mode
When the aircraft altitude is greater than 25,000 feet during a climb.
Prior to selecting the TOGA button what must be set in order to display the TO crossbar on the PFD
Flaps must be set to 1 or 2, aircraft weight must be set and TO speeds must be sent to the FMS
What computed takeoff speed reference is set in the TO mode
V2+15kts (AEO), in the case of OEI below V2 the speed reference will be set to V2
