|
What does HOLD mode mean? |
The autothrottle system does not reposition thrust levers while in HOLD mode |
|
|
What are the active modes of the autothrottle? |
IDLE HOLD THR THR REF SPD |
|
|
When both F/D's are turned OFF what mode does the A/T revert to? |
SPD mode. It will maintain speed set in the MCT window |
|
|
When will the A/T disconnect automatically? (4) |
A fault in the active mode is detected
When either reverse thrust lever is raised to reverse idle
If thrust levers are overridden in a manual landing after the autothrottle has began to retard thrust levers to idle
When both engines are shut down |
|
|
What does THR REF mode indicate? |
Thrust levers are advanced to the reference thrust limit |
|
|
What does the THR mode do? |
Applies thrust to maintain the climb/descent rate required by the pitch mode (will not be at thrust reference limit as displayed on N1 engine indications) |
|
|
When is TO/GA armed in flight? |
Flaps out of up OR glideslope is captured |
|
|
When does FLARE and ROLLOUT display? |
During Autoland (LAND3/LAND2) and Below 1500' RA |
|
|
Is LAND 3 a fail operational or fail passive condition? |
Fail Operational System redundancy is such that a single fault can not prevent the autopilot from making an automatic landing |
|
|
Is LAND 2 a fail operational or fail passive condition? |
Fail Passive Redundancy is such that single fault can not cause a significant deviation from the flight path |
|
|
At what altitude are changes in Autoland status inhibited with the exception of NO AUTOLAND? |
200' |
|
|
LNAV is armed prior to takeoff when will it become the active mode? |
At 50' RA and within 2.5 miles of first waypoint |
|
|
When does VNAV become the active mode after take off? |
400' |
|
|
During Autoland when does FLARE activate? |
40-60 RA |
|
|
During a manual landing at what altitude does the autothrottle go to IDLE? |
25' RA |
|
|
With autothrottle in HOLD mode, is stall protection provided? |
No |
|
|
If TO/GA is not selected by _____ KIAS then autothrottles can't be activated until ____' |
50 KIAS 400' |
|
|
In flight, with F/D switches off, pushing TO/GA will do what? |
Displays F/D bars |
|
|
Are TO/GA switches inhibited on the ground? |
Yes, TO/GA switches are enabled again once airborne. |
|
|
Pushing TO/GA once activates what A/T mode and rate of climb? |
THR 2000 FPM |
|
|
Pushing TO/GA twice activates what Autothrottle mode? |
THR REF Full go-around thrust |
|
|
When a new mode becomes active on the FMA how long is the green box around the mode? |
10 seconds |
|
|
During an autoland (LAND 3/2) when does ROLLOUT become active and when will it disconnect? |
Active at 2’ RA and will remain active until the autopilot is disconnected |
|
|
How is control feedback delivered to flight controls with Autopilot on? |
The AFDS sends signals to backdrive actuators to manipulate the controls (control wheel, column, rudder pedals) |
|
|
How does autothrottle provide stall protection? |
If autothrottle is ARMED but not active it will wake-up to provide stall protection to top of amber band in SPD mode |
|
|
If you push down the autopilot disengage bar what protection mode do you lose? |
Bank angle protection |
|
|
In APP mode below 1500' RA with LAND3/2 displayed will pushing the APP switch again cancel the mode? |
No, only if above 1500' |
|
|
Below 1500' with APP armed how can you change modes? |
Deselect A/P, both F/D. Then F/D on and A/P on, select new mode. OR TO/GA |
|
|
Will the autothrottles remain engaged when EEC switches to Alternate mode? |
Yes, regardless if it is soft or hard mode |
|
|
Can the rudder pedals disconnect the autopilot? |
Yes, only in an autoland with LAND 2/3 annunciated |
|
|
Is VNAV available if a dual FMC failure occurs? |
No |
|
|
How many minutes does the FLCH try and reach altitude if able with available thrust? |
2 minutes |
|
|
What are two ways you can get continuous thrust or climb power using the MCP? |
CLB CON or FLCH if there is a higher altitude in the MCP window |
|
|
What will occur on the FMA when a flight mode fault occurs? |
An amber line through the mode on the FMA |
|
|
VNAV PTH is the active pitch mode in descent. What A/T modes could you see? |
IDLE, HOLD or SPD |
|
|
VNAV PTH is the active pitch mode in climb. What A/T modes could you see? |
THR REF, SPD |
|
|
At 100 knots on the takeoff roll what does the system automatically do and why? |
At 100 knots the FMC take a baro snapshot. That altitude is used to activate VNAV |
