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
