What does the anti-skid warning light indicate?
The anti-skid warning light indicates that the system is turned off or there is a system failure.
What type of waring devices are usually provided for retractable landing gear?
A red light and A horn or aural device.
When does the aural device operate in a landing gear warning system?
When the throttles are retarded and the landing gear is not down and locked.
What type of position indicators are normally used to indicate that the landing gear is down and locked?
Normally there is a green light for each gear.
what positions of retractable landing gear normally have a position indicator?
Secured in the up position and secured in the down position.
What is a squat, or weight on wheels switch, and where is it located?

A microswitch. Commonly called squat switch or weight on wheels switch.
When should you check landing gear switches, lights, warning horn, or buzzer for proper operation?
During a landing gear retraction check, or swinging the landing gear.
How does a takeoff warning horn differ from a landing gear warning horn?
The takeoff horn is intermittent, whereas the landing gear warning is continuous.
What items may cause a takeoff warning horn to operate in a typical transport jet aircraft?
- Speed brakes not down.
- Flaps not in takeoff range.
- Auxiliary power exhaust door open.
- Stabilizer not in the takeoff setting.
What is the master caution light?

What is used to indicate the position of wing flaps?
A resistance-type remote indicating system.
What is the purpose of a Mach warning system?
It provides an aural warning that aircraft speed limits have been exceeded.
What is the purpose of the annunciator system?
To show current conditions and to notify of unsatisfactory conditions.
