Altitude Loss per Nautical Mile (NM) in aircraft design refers to the rate at which an aircraft’s altitude decreases when flying along a specific path, typically during the descent phase of an approach. This measurement helps pilots and air traffic controllers plan and execute descents safely and accurately. Here’s a definition and explanation:
Formula: The formula to calculate Altitude Loss per Nautical Mile is:
- Altitude Loss per NM is measured in meters per nautical mile (m/NM).
- Altitude Change is the difference in altitude (in meters) over the course of the nautical mile.
- Distance in Nautical Miles is the distance traveled by the aircraft along the specific flight path.
