AIR PROPERTIES - Output correction due to air properties.
Specified outputs presuppose the following air properties (as per ISO 3046):
Air pressure:
1000 mbar (750 mmHg)
Air temperature:
25ºC
Humidity: 30%
If the air deviates from these values, correction factors (in %) are found in the graphs below. Use the correction factors in
“calculation of engine output”
