Correction
Follow-up

Question 4

Which subsystem of the autopilot system could you consider the ‘“brains”

Answer 4

Error-sensing

Question 5

Which subsystem of the autopilot system could you consider the “muscles”

Answer 5

Servos in the controller system

Question 6

What is required for all autopilot systems?

Answer 6

All autopilot systems must have an emergency disconnect so that the autopilot can be over-ridden by the pilot

Question 7

Where can you find the requirements for aural warning systems?

Answer 8

Sections of FAR part 25

Question 9

Explain what type of work an A&P mechanic is allowed to perform on aural warning systems?

Answer 9

Inspect and test the system and repair where allowed per AMM

Question 10

What flight deck effects happen when landing gear is not down and locked, flaps are less than full retracted, and throttle is retarded to idle?

Answer 10

The landing gear warning system will signal the pilot with a continuous horn

Question 11

Explain the significance of aural warning systems for aircraft?

Answer 11

Loud and clear audible sounds to warn the crew of a serious problem or the aircraft in the wrong configuration for that stage of flight

Question 12

What are the three colors of indicated lights on an annunciator panel and what do they represent?

Answer 12

Green: indicates satisfactory condition
Yellow: indicates caution of a serious condition that requires further monitoring
Red: indicates unsatisfactory condition that requires immediate action

Answer 17

Inspect
Troubleshoot
Remove and reinstall
New installations STC form 337

Question 18

Explain three reasons why bonding wires are used?

Answer 18

They reduce radio interference by balancing the static electricity throughout the aircraft structure

Decrease possibility of lightening damage to control surface hinges

Reduce fire hazard by eliminating static charge sparking

Answer 24

Basic pitch and roll, attitude, airspeed, and vertical speed scale

Question 25

What does BITE perform?

Answer 25

Digital systems may automatically do a self-examination of their operating condition and diagnose the faults found
