Aircraft Instrument Systems Flashcards
What does a yellow arc on an instrument dial indicate?
caution
What can be used to perform a static check of a manifold pressure indicator?
atmospheric pressure
What test is required after the replacement of components connected to a pitot static system?
leak test
What does a tachometer indicate?
speed of the crankshaft or compressor
What is used as a reference for range marking instruments?
TCDS, or airplane flight manual
Who can apply range markings to a dial face?
an A&P
Why are slippage marks used on instrument glass covers?
to aid in noticing if the glass has shifted
When range markings are placed on an instrument glass, what precaution must be taken?
that it is marked in accordance with approved data
What aircraft instrument may be used to check manifold pressure indicator for correct indication?
altimeter
what indication errors may be found in altimeters?
scale error, hysteresis, barometric scale calibration
What flight instruments are usually connected to a pitot static system?
airspeed, VSI, altimeter
Why is it undesirable to clear obstructions from pitot-static holes with a tool?
it might alter the shape of the hole.
What methods are used to drive turn and bank indicators?
pneumatic or electric
What causes an electric-driven gyro rotor to tilt when the aircraft is turned?
pull of gravity not aligned with gyro axis
What is a synchro-type remote indicating system?
electric system used to transmit information
