2 - King - Flight Instruments Flashcards
How should a pilot determine the direction of bank from in attitude indicator such as the one illustrated
By the relationship of the miniature airship to the deflected horizon bar
Glass cockpit aircraft refer to
Aircraft with both digital and limited number of analog instrument for backup.
Gyroscopic Precession on a heading indicator
Drifting from heading due to friction and earth’s rotation. Realign with magnetic compass during straight and level flight.
To receive accurate indications during flight from a heading indicator, the instrument must be
Periodically re aligned with the magnetic compass as the gyro precesses.
A turn coordinator provides and indication of the
movement of the aircraft about the yaw and roll axes.
Pitot system provides impact pressure for which instrument?
airspeed indicator
Static port
Provides calm air pressure to altimeter, vertical speed indicator and air speed indicator.
If the pitot tube in the outside vertical vent become clogged which instrument would have be affected?
The altimeter, airspeed indicator, and vertical speed indicator.
Which instrument will become inoperable if the pitot tube becomes clogged?
Airspeed indicator.
Which instruments will become inoperable if the static vent becomes clogged?
altimeter, vertical speed indicator and air speed indicator.
Default barometric pressure scale is
29.92”
Indicated Altitude
Displayed in the altimeter.
True Altitude
Vertical distance above sea level
Absolute Altitude
Vertical distance above the surface
Pressure Altitude
Barometric pressure scale set to 29.92”
barometric ratio is?
1 inch of barometric pressure equals 1,000 feet.
From high to low, look out below
Flying from high pressure area to low pressure area, the altimeter indicates too high of a reading.
From low to high below, clear the sky
Flying from low pressure area to high pressure area, the altimeter indicates too low of a reading.
If it is necessary to set the altimeter from 29.15 to 29.85 what change occur?
700-foot increase in indicated altitude.
If a pilot changes the altimeter settings from 30.11 to 29.96 what is the approximate change in indication?
Altimeter will indicate 150 feet lower.
If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted altimeter will indicate?
Lower than the actual altitude above sea level
If a flight is made from an area of high pressure into an area of low pressure without the altimeter setting being adjusted altimeter will indicate?
Higher than the actual altitude above sea level
How do variations in temperature affect the ultimate?
Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.
The ANDS compass error acronym stands for?
Accelerate compass turns North
Decelerate compass turns South
The NO compass error acronym stands for?
North Opposite
The COSUN compass error acronym stand for?
Compass Overshoots South Undershoots North
In the northern hemisphere a magnetic compass will normally indicate initially a turn tours the East if?
If left turn is entered from a northern heading
In the door then hemisphere a magnetic compass will normally indicate initially a turn towards the West if?
In right turn is entered from a northern heading
