Altimeter setting is the 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.
How do variations in temperature affect the altimeter?
Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.
Higher temperatures expand the pressure levels and the indicated altitude is higher than true altitude.
Lower temperatures lower the pressure levels and the indicated altitude is lower than true altitude.
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 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 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.
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.
If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs?
70-foot increase in indicated altitude.
70-foot increase in density altitude.
700-foot increase in indicated altitude.
The pitot system provides impact pressure for which instrument?
Altimeter.

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
