Multiple Choice

___ means height above airport and is expressed in feet.

In aviation, height relative to a fixed point like an airport is commonly expressed with an acronym. HAA stands for Height Above Airport, and it is given in feet. This label is the standard shorthand used on charts and in communications to indicate how high something is above the airport’s reference elevation. The other options use nonstandard phrasing or aren’t the commonly used term, so the acronym form is the precise match. For example, if an aircraft is 2,500 feet HAA, it’s 2,500 feet above the airport elevation.
