|
Name several of the indication errors that may be found in altimeters |
Scale errors, hysteresis, friction, installation |
|
What is the signal source in an electrical resistance type temperature indicating system? |
A temperature bulb or sensing element |
|
What type of temperature sensing system is normally used to measure a turbine engine exhaust gas temperature? |
Thermocouple type system |
|
What operating parameter is indicated by a tachometer? |
Engine RPM |
|
what is the name of the effect that causes a gyro to respond to an applied force at a point 90 degrees further in the direction of rotation? |
Gyroscopic precession |
|
What are the three sources of power used to drive a gyro turn indicator? |
Air from a vacuum or pressure source, or an electric motor |
|
What are two items that should be considered during inspection of a magnetic compass? |
The fluid must be clear, the housing must be full with no bubbles, the card must be legible and the lubber line intact, compass should be properly calibrated |
|
in what way do magnetic fields generated by electrical equipment and steel parts in the airplane affect a magnetic compass? |
Stray magnetic fields deflect the compass from correct alignment with the Earth's magnetic field |
|
Describe the basic operating concept of a synchro type remote indicating system |
A remote transmitter electrically signals a receiver inside the instrument |
|
What aircraft instruments are connected to the pitot-static system? |
The altimeter, vertical speed indicator, AirSpeed and a Mach meter in high-performance Jets |
|
Why should you avoid cleaning obstructions from the sensing holes in a pitot static system with a tool? |
The holes are aerodynamically critical |
|
After components in a pitot static system have been replaced, what tests or inspections are required? |
Static system leak test specified by FAR 91.411 |
|
What quantity is accurately measured by a capacitance type fuel quantity indicating system? |
The mass of fuel |
|
Who is authorized to apply the range markings to an instrument dial face? |
The manufacturer or a certified instrument repair station |
|
What is the purpose of a slippage mark on an instrument glass? |
to indicate if the glass has moved, which could cause incorrect range markings on an instrument that has the range markings painted on the glass |
|
What references should be consulted to determine the proper range markings for aircraft instruments? |
The aircraft maintenance manual, aircraft flight manual, type certificate data sheets or aircraft specifications |
|
What is the meaning of a yellow mark on an instrument? |
A caution or limited flight operations range |
|
What is the reason for swinging a compass and how is it accomplished? |
To compensate for deviations, caused by magnetic fields in the aircraft, by adjusting the compensating magnets |
