Automatic Flight Flashcards
When the FMC(VNAV) controls the speed, what does the IAS/MACH window display?
IAS/MACH window is blank
In addition to the MCP heading window, where else is selected heading displayed?
SEL HDG is displayed on the mini map
What is the effect of:
- First push of A/P disengage switch?
- Second push?
First push will:
- disengage the autopilot
- illuminate the master warning lights
- display EICAS warning AUTOPILOT DISC
- sound an aural warning
- in case of automatic disconnect, reset master warning lights, EICAS warning msg and aural warning
Second push will reset:
- master warning lights
- EICAS warning msg
- aural warning
List the methods for disconnecting the A/T
Pushing either A/T disconnect switch
Positioning the A/T ARM switch to OFF
When does HOLD mode engage during takeoff?
At 80 knots
To which AFDS mode does the bank limit selector apply?
Heading select or Track select
Can the IAS/MACH window display a speed when VNAV is engaged?
Yes, by pressing the IAS/MACH selector
When are FLARE and ROLLOUT engaged?
FLARE at 47’ RA
ROLLOUT at touchdown with weight on wheels
Until what point does ROLLOUT mode provide guidance?
Autopilot disengaged
How can APP mode be disengaged before LOC or G/S capture?
By pressing APP again
How can APP mode be disengaged with LOC captured and G/S armed?
By selecting HDG/TRK SEL or HDG/TRK HOLD
How can APP mode be disengaged with G/S captured and LOC armed?
By selecting any other pitch mode except VNAV
How can APP mode be disengaged with LOC and G/S captured?
By selecting TO/GA or by disengaging autopilot and turning both flight director switches OFF.
In VNAV, which altitude will the AFDS capture during climb or descent; the on selected in the MCP ALT window or the FMC target altitude?
Whichever altitude is reached first, i.e. the most limiting.
If armed, at what height will VNAV engage during takeoff?
400’
During a VNAV climb, the aircraft levels off at an intermediate altitude which has been selected on the MCP. What will be the FMA pitch mode annunciation?
VNAV ALT
What is the maximum localizer intercept angle?
120 degrees
What does a green box around an FMA mode mean?
Mode is engaged/activated. Shown for 10sec.
What do the F/D bars command at:
- Takeoff prior to 80kts
- Lift-off
- Initial pitch up of 8 degrees
- Pitch attitude to maintain target speed V2+15 or airspeed on rotation +15.
How are F/D pitch commands during takeoff affected by an engine failure?
Pitch command will be for target speed of V2 or speed at lift-off, whichever is greater.
What is the range of the V/S selector?
-8000 to +6000
How is a cruise climb initiated?
Select new altitude on MCP, then press altitude selector to update cruise altitude in FMC cruise page.
When is the ALIGN maneuver commenced?
500’ RA
What heading does the AFDS command when the following modes are engaged?
Heading select
Heading hold
Heading select - The selected heading in the MCP window
Heading hold - Present heading
What indication does Altitude Alert provide:
- Approaching the selected altitude
- Deviation from the selected altitude
Approaching: -At 900’ prior a white highlighted box displayed around current and selected altitude.
Deviating: -At 200’ away an amber box displayed around the current altitude and EICAS “ALTITUDE ALERT” displayed.
When is altitude alerting inhibited?
Glideslope captured or
Landing flaps selected and Ldg gear down and locked
What is the difference between THR and THR REF autothrottle modes?
THR - A/T commands thrust as required by the pitch mode
THR REF - A/T sets the reference thrust displayed on EICAS
At what altitude will LNAV activate on go-around?
Provided valid missed approach patch exists:
- F/D only, 50’ RA
- A/P engaged, 200’ RA
With LNAV armed and on intercept heading, at what distance from active leg will it engage?
2,5nm
Within what time will the AFDS attempt to reach the target altitude in FLCH?
2 minutes if able with available thrust
What is the target V/S in FLCH?
500fpm for each 1000’ altitude change
What happens if pressing TO/GA switches on the ground above 80 knots?
LNAV and VNAV disarms
When can the autothrottle be activated on the ground?
Below 50 knots with flaps out of up
What happens with autothrottle if pressing TO/GA switches on the ground above 50 knots?
Autothrottle is inhibited until reaching 400 feet
Can APP mode be deselected after LOC and G/S capture?
Yes, if above 1500 feet RA
When is TO/GA mode armed in flight?
G/S captured and flaps out of up
When is FLARE and ROLLOUT armed?
Below 1500 RA
When does flare mode activate?
Between 60 and 40 feet RA
When activating TO/GA in flight, what is the minimum climb rate?
Autothrottle engages in THR mode to maintain minimum 2000fpm
