Altitude FAQs:


Q: Is altitude a distance measurement?

A: Yes, and usually in the vertical or "up" direction, between a reference datum and a point or object.

Q: Is altitude commonly used to mean the height above sea level of a location?

A: Yes, and in geography the term elevation is often preferred for this usage.

Q: Is altitude sometimes defined to begin at 2,400 meters above sea leve?

A: Yes, and ometimes defined to begin at 2,400 meters above sea level.

Q: Is altitude the elevation above a standard datum air-pressure plane?

A: Yes, Pressure altitude is used to indicate "flight level" which is the standard for altitude reporting in the U.S. in Class A airspace. Pressure altitude and indicated altitude are the same when the altimeter setting is 29.

Q: Is altitude the height of the aircraft above the terrain over which it is flying?

A: Yes.

Q: Is altitude measured using either mean sea level or local ground level as the reference datum?

A: Yes.

Q: Is altitude the altitude corrected for non-ISA International Standard Atmosphere atmospheric conditions?

A: Yes.

Q: Is altitude the pressure altimeter?

A: Yes, and which is an aneroid barometer with a front face indicating distance instead of atmospheric pressure.

Q: Is altitude the actual elevation above mean sea level?

A: Yes.

Q: Are altitudes problematic?

A: Yes.

Q: Is altitude the reading on the altimeter when it is set to the local barometric pressure at mean sea level?

A: Yes.
