Autoflight Flashcards
What systems make up the Auto Flight Control System? (AFCS)
Flight director
Autopilot
Auto throttles
Which panel hosts the controls for FD, AP, & AT, plus lateral and vertical ref/mode selection and course selection?
AFCS panel
What does pushing the FD button do?
Engages/disengages FD on that PFD
What does the AT button do?
Engages/disengages the AT
Selects the source of the speed ref between MAN and FMS
What does the HDG button do?
Heading mode if pushed once, Roll mode if pressed again
Bank button does what?
Toggles between +/- 15* and +/- 30* bank angles
What is the up and down range of the FPA mode
9.9* up and down
How can the flight path angle/ref line be selected?
By rotating the FPA knob
What do the outer and inner rings on the ALT knob select?
Outer selects alt by 1000’s
Inner selects by 100’s
What does the SRC button do?
Alternates between PFD 1 & PFD 2 FMA modes as the source for the AP
When AP is engaged, what does pressing the TCS button on the stick do?
Activates TCS (AP override) as long as your not in TO/GA
Where are the TO/GA and AT/DISC buttons located?
Throttles
With AP engaged will it disengaged if any force is applied to a stick?
Yes
What are the 2 FD cues present?
FD cue (magenta circle) and the TO crossbar
What does the green Flight Path Vector cue indicate?
Current flight path in reference to the horizon line
Where is the Flight Mode Annunciator located and what will it show?
FMA located in upper part of both PFD’s, annunciation for AT, approach status, lateral and vertical modes
FMA color codes for normal operation
Magenta - FMS active/engaged modes Green - Non-FMS modes active/engaged modes White - Armed modes Amber - Alert condition Red - Abnormal condition
What does an amber LIM on the FMA mean?
AT is in speed mode but speed is not achievable due to limited N1 rating
What are the two precision approach capabilities of the plane?
APPR 1 or APPR 2
How do you cancel the AP aural alert?
Press AP/PTY button on the stick
When will the plane auto 1/2 bank mode
Aircraft altitude greater than 25,000ft in a climb
Prior to selecting TOGA what must be set in order to see takeoff crossbar on PFD?
Flaps 1 or 2, W&B set, and takeoff speeds must be sent to the FMS
What computed Takeoff speed reference is set in TO mode?
V2 + 15 kts (Both engines), in the case of an engine failure below v2 the speed ref will be v2
What altitudes are associated with the ILS app. checkpoints to try and engage the highest system capability available?
1500ft RA & 800ft RA
