PerformanceTake-off and Landing Performance
Pressure Height
The height of an aircraft or aerodrome measured above the standard datum plane. It is determined by setting the altimeter subscale to the standard pressure setting of 1013.2 hPa.
Key Points
- •Measured with reference to the 1013.2 hPa standard pressure setting.
- •Can be calculated given airfield elevation and local QNH.
- •Combined with outside air temperature (OAT) to determine density height.
Exam Relevance
Forms the essential basis for calculating density height, which is critical for accurate take-off, climb, and landing performance charts.
