types of altitude

Question 1

absolute altitude

Answer 1

the vertical distance of the aircraft above the terrain. It is expressed as a number of feet AGL (above ground level)

Question 2

true altitude

Answer 2

the vertical distance of the aircraft above sea level. it is expressed as a number of feet above MSL (mean of sea level)

Question 3

indicated altitude

Answer 3

the altitude read directly from the altimeter after it is set to the local altimeter setting

Question 4

pressure altitude

Answer 4

The altitude indicated on the altimeter when the altimeter setting window is adjusted to the ISA sea-level pressure of 29.92 in. of Hg

Question 5

density altitude

Answer 5

The pressure altitude corrected for non-standard temperature variations

Question 6

when will density altitude and pressure altitude be the same?

Answer 6

when the temperature is above standard

Question 7

When will pressure altitude and density altitude the different?

Answer 7

When the temperature is below standard. Density altitude will be lower than pressure altitude
