Instruments 1-46 Flashcards
The ______receives pitot/static air inputs and develops airspeed, altitude, and climb rate parameters for use by the navigation and flight instrument systems
air data computer (ADC)
The air data computer provides air data corrected for temperature, position or
instrument error.
False. It does not
The ADC provides air data outputs to the following instruments/systems:
ASI Altimeter VSI EFIS Transponder TAD Overspeed warning system TAS PMU GPS AHRS
A ____________ indicates maximum operating airspeed.
striped red and white barber pole pointer
Mach information is blanked
below _____ Mach.
0.40
What are the STANDBY FLIGHT INSTRUMENTS?
Standby mechanical attitude, altitude, airspeed, and turn/
bank indicators and compass
The standby instruments are normally powered by the _______
battery bus
In event of a battery bus failure, the standby instruments are
powered by the _____
auxiliary battery
Standby instrument lighting can be controlled by the light panel on the left side of the cockpit, when til AUX battery is powering the system?
False. Standby instrument lighting operates at a fixed level when the auxiliary battery is powering the system.
The standby attitude indicator operates from the auxiliary battery during a main battery
electrical failure, and retains sufficient energy in the gyro to provide accurate pitch and roll indications within ____ for a period of ____ minutes after all electrical power.
6°; 9
If the auxiliary battery, is lost together with the battery, the standby ATI will stop functioning immediately.
False. It will provide accurate pitch and roll indications within 6° for a period of 9 minutes after all electrical power, including the auxiliary battery, is lost.
When should the ST BY ATI be caged and locked
Whenever power is to be applied to, or removed from, the standby attitude indicator
How can you determine if there is no electrical power being supplied to the standby attitude indicator?
a red off flag, placarded OFF,
will be visible on the left side of the indicator
In the event of a main battery/electrical failure which has required the use of the auxiliary battery, when will the OFF flag show?
the OFF flag will remain out of
sight until the auxiliary battery fails. Once the flag is visible
after auxiliary battery failure, the indicator will be operable
for at least 9 minutes.
At altitudes below zero feet MSL, what is shown in the standby altimeter?
NEG is displayed in the 10,000-foot counter
