Question
What is an Aviation Reference Height?
Solution
Aviation Reference Height, also known as Decision Height, is a specified altitude or height in the Precision Approach or approach with vertical guidance at which a missed approach must be initiated if the required visual reference to continue the approach has not been established.
Here are the steps to understand it:
- It is a term used in aviation, specifically in the approach phase of a flight.
- This is the height at which a decision must be made during an approach to land.
- If the pilot has the runway in sight at this height, they may continue to land.
- If they do not have the runway in sight, they must execute a missed approach procedure.
- The Aviation Reference Height is determined by considering various factors such as the altitude of the airport, the terrain, and the typical descent rate of the aircraft.

An aerial survey is conducted with a flying height (H) of 2000 m above msl. The baseline distance (B) between two photographs is measured as 20 m. If the focal length of the camera (f) is 50 mm, and the X-parallax (P) is measured as 0.1 cm, the object height (h) between the two points will be: 1000 m 500 m 400 m 200 m
