If an altimeter setting is not available before flight, to which altitude should the pilot adjust the altimeter?
A-the elevation of the nearest airport corrected to mean sea level.
B-the elevation of the departure area.
C-pressure altitude corrected for nonstandard temperature.
B-the elevation of the departure area.
Prior to takeoff, the altimeter should be set to which altitude or altimeter setting?
A-the current local altimeter setting, if available, or the departure airport elevation.
B-the corrected density altitude of the departure airport.
C-the corrected pressure altitude of the departure airport.
A-the current local altimeter setting, if available, or the departure airport elevation.
At what altitude shall the altimeter be set to 29.92, when climbing to causing flight level?
A-14,500 feet MSL.
B-18,000 feet MSL.
C-24,000 feet MSL.
B-18,000 feet MSL.
Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates:
A-calibrated altitude at field elevation.
B-absolute altitude at field elevation.
C-true altitude at field elevation.
C-true altitude at field elevation.
How do variations in temperature affect the altimeter?
A-pressure levels are raised on warm days, and the indicated altitude is lower than true altitude.
B-higher temperatures expand the pressure levels and the indicated altitude is higher than true altitude.
C-lower temperatures lower the pressure levels and the indicated altitude is lower than true altitude.
A-pressure levels are raised on warm days, and the indicated altitude is lower than true altitude.
What is true altitude?
A-the vertical distance of the aircraft above sea level.
B-the vertical distance of the aircraft above the surface.
C-the height above the standard datum plane.
A-the vertical distance of the aircraft above sea level.
Under what condition will true altitude be lower than indicated altitude?
A-in colder than standard air temperature.
B-in warmer than standard air temperature.
C-when density altitude is higher than indicated altitude.
A-in colder than standard air temperature.
Colder, true lower.
What is absolute altitude?
A-the altitude read directly from the altimeter.
B-the vertical distance of the aircraft above the surface.
C-the height above the standard datum plane.
B-the vertical distance of the aircraft above the surface.
What is density altitude?
A-the height above the standard datum plane.
B-the temperature pressure altitude corrected for nonstandard temperature.
C-the altitude read directly from the altimeter.
B-the temperature pressure altitude corrected for nonstandard temperature.
What is pressure altitude?
A-the indicated altitude corrected for position and installation error.
B-the altitude indicated when the barometric pressure scale is set to 29.92.
C-the indicated altitude corrected for nonstandard temperature and pressure.
B-the altitude indicated when the barometric pressure scale is set to 29.92.
