Auto Landing Flashcards
What components are required for an auto land?
ILS receivers - auto pilot - auto throttle - radio altimeter
What is the main purpose of Dutch roll filter?
To distinguish the yaw of Dutch Roll from yaw in a turn.
What is the main function of the control surface position sensors?
Comparing the directed inputs with the actual surface movement.
In an autopilot system, the functions that control the path of the aircraft are the…
Guidance system
When engaged, the autopilot manoeuvres the aeroplane in accordance within a set of control laws. The purpose of these control laws is to…
Prevent unacceptable loads
In the event of a failure, a fail-operational flight control system will operate as a fail blank system.
Passive
The purpose of an FCU/MCP is to…
Operate automation modes.
What does it mean when an autopilot mode is captured?
The aircraft is heading for the relevant parameter.
What is the purpose of the Flight Director (FD)?
Helps with attitude control.
What does the Flight Director (FD) indicate when engaged?
- Magnitude and direction of flight control input
- Only direction of flight control input
- Attitude of the aircraft

In case of a Radio Altimeter (R/A) failure, is the ability to perform an automatic landing affected?
Yes, because the R/A is used during the blank.
Flare.
What does fail passive mean?
Crew must take over.
The components of an autopilot system are the:
1 – actuators
2 – autopilot mode control panel
3 – EFIS control panel
4 – mode annunciator panel (FMA)
The combination that regroups all of the correct statements is…
1,2,4
In an autopilot system, the basic stabilisation modes are:
1 – Altitude hold
2 – Pitch angle hold
3 – Bank angle
4 – IAS hold
The combination that regroups all of the correct statements is…
2,3
The purpose of the Flight Mode Annunciator (FMA) is to…
Check any autopilot selections.
Translate : FMA of the PFDs.
Flight mode annunciator of the primary flight displays.
What is the basic principle of a closed loop system?
Measure a controlled variable.
During a final approach, the flight director system is engaged in the G/S mode (tracking of ILS Glide Slope). The position of the horizontal command bar indicates:
1 – the position of the aircraft relative to the ILS Glide Slope
2 – the correction to be applied to the pitch angle in order to capture and follow the ILS Glide Slope
3 – the pitch angle of the aircraft
The combination that regroups all of the correct statements is…
2
When engaged in the FMS lateral navigation mode (NAV or LNAV) the autopilot uses the command provided by the…
FMS
What will happen if the pilot uses manual trim while the autopilot is engaged?
Autopilot disconnects.
Assuming the autopilot is in heading hold mode, what would happen to the autopilot if the flux valve started drifting in an aircraft equipped with a single flux valve?
Autopilot drift.
An inner loop control (stabilisation) is…
control the movements of the aircraft around its center of gravity.
When could a pilot use the auto trim on a non Fly-By-Wire aeroplane?
When auto pilot is engaged
