Airplane Systems

What is absolute altitude?

• The altitude read directly from the altimeter

• The vertical distance of the aircraft above the surface

• The height above the standard datum plane

What is true altitude?

• The vertical distance of the aircraft above sea level

• The vertical distance of the aircraft above the surface

• The height above the standard datum plane

What is density altitude?

• The height above the standard datum plane

• The pressure altitude corrected for non-standard temperature

• The altitude read directly from the altimeter

What is pressure altitude?

• The indicated altitude corrected for position and installation error

• The altitude indicated when the barometric pressure scale is set to 29.92

• The indicated altitude corrected for nonstandard temperature and pressure

Altimeter setting is value to which the barometric pressure scale of the altimeter is set so the altimeter indicates

• Calibrated altitude at field elevation

• Absolute altitude at field elevation

• True altitude at field elevation

Under what condition is indicated altitude the same as true altitude?

• If the altimeter has no mechanical error

• When at sea level under standard conditions

• When at 18,000 feet MSL with the altimeter set at 29.92

Under what condition is pressure altitude and density altitude the same value?

• At sea level, when the temperature is 0* F

• Whe the altimeter has no installation error

• At standard temperature

Under which condition will pressure altitude be equal to true altitude?

• When the atmospheric pressure is 29.92" Hg

• When standard atmospheric conditions exist

• When indicated altitude is equal to the pressure altitude

If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate

• The actual altitude above sea level

• Higher than the actual altitude above sea level

• Lower than the actual altitude above sea level

If a flight is made from an area of high pressure into an area of lower pressure without the altimeter setting being adjusted, the altimeter will indicate

• Lower than the actual altitude above sea level

• Higher than the actual altitude above seal level

• The actual altitude above sea level
