Aerotrain Autopilot CBT Flashcards
Name the 4 blocks in the AP system diagram
- Sensor Info
- Computer (Pilot control input sources)
- Computation and Processing
- Loads and Output devices
How does an AP perform many of the functions a human pilot would?
Using electrical, electronic and electrohydraulic devices
In the autopilot system block diagram what does the sensors do?
Detects various changes in Aircraft Attitude
Early autopilots were designed to do what?
Keep the wings in level flight
What is the role of the computer?
Calculates the size of the output signal and which axis to send it to
What is another name in which a single-axis system in a small single engine aircraft is referred to?
Wing-leveler
What do Autopilot systems from simple to complex do?
Reduce the pilot workload and mental fatigue throughout all the areas of the flight envelope
AFCS in modern aircraft are uniquely tailored to specific aircraft?
True
While a particular AP mode may be common between different aircraft types, what will differ in their respective Autopilot systems?
The GAIN programming
What is the aerodynamic function that an AP must provide?
Stability
What is the AP designed to provide?
Pitch, roll, yaw, and reference attitude
For an AP to maintain stability, what 3 things must take place?
Pilots DESIRED and ACTUAL attitude then compare
What term is used for the difference between desire and actual attitudes?
Error
What four items provide attitude and heading signals to develop attitude and flight path stabilization signals?
Vertical gyro, Directional gyro, Rate gyro, Accelerometers
What part of the AFCS is considered the brain and the musle?
Computer and Servos
What is the role of the AP computer?
Compute the proper responses and provide output signals to the electric and/or hydraulic actuators which move the control surfaces
What is the function of the AFCS control panel?
Engage and disengage autopilot and select operating mode
After the control surfaces respond to the output signals from the computer, what must occur?
Feedback
How do you classify AP?
By the number of axes being controlled
A 1 axis AP controls what?
Ailerons
A 3-axis AP controls what?
Ailerons, elevators, rudders
The basic autopilot is composed of what?
Controller, gyro, servos, and computer
