Aircraft Instruments Flashcards
Which instruments are primary for pitch, bank, and power respectively when entering a constant rate of climb in level flight?
Attitude indicator, heading indicator, manifold/tachometer
To level off from a descent maintaining the descending airspeed, the pilot should lead the desired altitude by approximately
50 feet
To level off from a descent to a specific altitude, the pilot should lead the level off by approximately
10% of the vertical speed
Rate of turn can be increased and radius of turn can be decreased by
Decreasing airspeed and decreasing bank
If the pitot tube ram air pressure hole and drain hole become obstructed, the airspeed indicator will operate
Like an altimeter as the aircraft climbs and descends
If while in level flight, it becomes necessary to use an alternate source of static pressure vented inside the plane, what should the pilot expect?
The VSI to momentarily show a climb
Which (primary) instrument provides the most pertinent information for pitch control in straight and level flight?
Altimeter
When flying directly over a published airborne VOR checkpoint, what is the maximum error allowed for in flight?
Plus or minus 6 degrees of the designated radial
For maintaining level flight, what instrument would be the least appropriate for determining the need for a pitch change?
Attitude indicator
Which condition would cause the altimeter to indicate a lower altitude than actually flown?
Air temperature being warmer than standard. When air is warmer than standard, the altimeter reads lower than true
Erros in both pitch and bank indication on an attitude indicator are usually at a maximum when are aircraft rolls out of a
180 degree turn
The rate of turn at any airspeed is dependent upon
The horizontal lift component
During normal operation of a attitude indicator, what attitude indication should you see when rolling out from a 180 degree skidding turn to straight and level coordinated flight?
The miniature aircraft shows a turn in the direction opposite the skid
What is the primary bank instrument while transitioning from straight and level flight to a standard rate turn to the left?
Attitude indicator
What information does a mach meter present?
The ratio of aircraft true airspeed to the speed of sound
To level off at an airspeed higher than the descent speed, assuming a 500 fpm descent, the addition of power should be made at what altitude?
100-150 feet above the desired altitude
If the OAT increases during a flight at constant power and at a constant altitude, the true airspeed and altitude will
The true airspeed will increase and the true altitude will increase
Which practical test should be made on the electric gyro instruments prior to starting the engine?
Turn on the electrical power and listen for any unusual or irregular mechanical noise
Which condition during taxi indicates that the attitude indicator is unreliable?
The horizon bar tilts more than 5 degrees during taxi turns
One characteristic that a properly functioning gyro depends upon for operation is the
Resistance to the deflection of the spinning wheel or disc
Remote indicating compass correction procedures
A right deflection indicates a clockwise error of the compass card and a left deflection indicates a counterclockwise error
