What is the reason for swinging the compass and how is it accomplished
Try compensate for deviations caused by the magnetic fields in the aircraft by adjusting the compensating magnets
Why are transport category aircraft equipped with a master caution and warning system
To alert the crew that a malfunction has occurred and corrrective actions may be required
How is a pilot alerted that an anti-skid system has automatically returned to a manual brake system?
By a warning light.
What is the significance of an anti-skid warning?
The system is off or has failed.
By what usual means does the stall warning system in a small aircraft alert the pilot of an impending stall?
An audible leer and /or a warninglight.
What devices are used to provide warnings for a retractable landing gear system?
A hom or other aural device, and a red warning light or light
How can a pilot determine that the landing gear is down and locked
A green light or lights and / or another type of visual indicator.
Name at least two conditions that would activate a takeoff configuration warning system in a jet transport aircra
Incorrect leading or trailing edge flap position, stabilizer position, or speed brake not stowed. The manufacturer may establish other conditions
What landing gear positions must be indicated by regulations?
Down and locked and up and locked.
Under what conditions will a landing gear aural warning sound?
When the throttle is retarded and the landing gear is not down and locked.
How does a takeoff configuration warning differ from a landing gear warning?
Takeoff warnings are usually an intermittent horns while landing gear warnings are steady
What is the function of a Mach airspeed warning system?
To alert the pilot that the never-exceed airspeed limit has been reached or exceeded.
What systems are commonly used to activate the landing gear warning systems
The throttles (thrust levers) and the wing flaps.
Why do airplanes with bleed air anti-icing of the wing leading edge have an anti-ice overheat light(
To indicate an over-temperature condition, usually as the result of a break in the bleed air ducts.
What warning system may be required when a nickel-cadmium battery is installed in an aircraft?
A battery temperature monitoring system.
At what time would a check of a landing gear warning system normally be made?
- During a landing gear retraction test.
What is the purpose of an annunciator system?
To show, by means of a warning light, that some system parameter requires attention by the flight crew.
If an aircraft with retractable landing gear has only one green light to indicate the gear is down and locked, how will the switches be connected, in series or in parallel
-In series.
Where would you locate the procedures for checking and adjusting the landing gear switches?
In the aircraft manufacturer’s manual.
. What is the usual means for alerting the crew of a jet transport that the cabin doors are not properly closed?
A warning light.
Why are transport category aircraft equipped with a master caution and warning system?
To alert the crew that a malfunction has occurred and corrective action may be required.
