Lecture 18 (Emily)

Question 1

What are the 3 types of flight control system

Answer 1

Mechanical, hydro Mechanical, and fly by wire

Question 2

Which of the flight control systems are irreversible (i.e the wind wont cause the pedal to move in the plane)

Answer 2

Hydro mechanical and fly by wire

Question 3

What do you need to make sure you have in fly by wire systems for saftey?

Answer 3

redundancy , also good to have artificial feel systems so pilot can feel what doing each thing would do

Question 5

Briefly explain how PID works?

Answer 5

read sensors, calculate corrections and then apply corrections

Question 6

In a PID controller what does the integral component do?

Answer 6

adds error values from the past

Question 7

In a PID controller what does the derivative component do?

Answer 7

Tells you how fast you are approaching target

Question 8

What is an aircraft stability augmentation systems

Answer 8

a thing that uses PID, sensors , actuators in order to keep the aircraft stable, especially during disturbances. Doesnt think about pilot

Question 9

What are the problems with original SAS’s

Answer 9

less responsive to pilot input
lots of redundancies

Question 10

What are the problems with a flying wing

Answer 10

unstable in yaw (therefore need a FBW)

Question 11

What is a control augmentation system?

Answer 11

Same as SAS but takes pilot inputs into consideration
