Autopilot Flashcards
Inner loop controls what
Rotary motions
Outer loop controls what
Translatory motions
What allows the pilot to override the auto pilot
Torque limiter
How is the yaw rate signal used
It has to pass a band pass filter and will be adapted inversely proportional to the airspeed
What indications are given to the pilot in FD mode and where are they shown?
Roll and pitch commands are shown on the ADI or PFD
What are the three takeoff speeds
V1 decision speed
Vr rotation speed
V2 safety speed
When does the yaw bar change to a roll bar during takeoff
30ft
What is the frequency for Dutch roll
0.25 hz (one oscillation every 4 seconds)
Which sensor is used for yaw dampening
Rate gyro about vert axis
What signal does yaw align use
Preselected course
What signal does yaw rollout use
Localiser deviation and heading error
How is the thrust error signal derived
Calculated thrust compared with highest engine thrust
LVTO is defined as
RVR of less than 400m
Cat 1 approach condition
200ft DH
1800ft RVR
Cat 2 approach conditions
200-100ft DH
984ft RVR
Cat 3a approach conditions
100ft DH
656ft RVR
Cat 3b approach conditions
50-0ft DH
656ft RVR
Cat 3c approach condition
No DH
No RVR
What is the Alert Height
The height above the ground defined by the manufacturer above which the landing can be terminated, below which the landing must continue. Cat 3 approach
What equipment is required for all decision heights below 30m (100ft)
Two ILS glide path and localiser receivers one to the pilot, one to the copilot
One Rad Alt with display at each seat
DH above 50ft (15m) should be fail….
Passive
DH below 50ft (15m) should he fail…
Operational
Fail safe flight control systems
HOPS cannot be suppressed by the system
Cat 2 capability landing
One fail passive autopilot is operational and sufficient redundancy is available
Cat 3 A (single) capability
One fail passive autopilot and one auto thrust are operational
Cat 3B capability
Two fail passive autopilots and one auto thrust are operational
Where is the auto land warning?
In the glare shield in field of view
