Altimeter Operation and Errors Flashcards

1
Q

Altimeter setting is:

A

the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates true altitude at field elevation. (another case when indicated altitude equals true altitude is at sea level with standard conditions.)

Q

If you fly from an area of HIGH PRESSURE into an area of LOW PRESSURE without the altimeter setting being adjusted

A

if you maintain a constant indicated altitude, the altimeter would indicate HIGHER than the actual altitude above sea level.

Q

If you fly from an area of LOW PRESSURE into an area of HIGHER PRESSURE without the altimeter setting being adjusted

A

if you maintain a constant indicated altitude, the altimeter will indicate LOWER than the actual altitude above sea level.

Q

If you adjust the pressure setting window from a SMALLER number to a LARGER number

A

the hands will move to larger numbers at the rate of approximately 1,000 feet of indicated altitude for each one inch Hg adjustment in the setting window.

Q

To find pressure altitude

A

set 29.92’ Hg in the setting window of the altimeter and read pressure altitude from the hands
