- Station reference altitude (m)
- Altitude of station in meters. Typically, the airport reference height.
- Declination (deg, - for west)
- In degrees, use the − character to indicate west, for example − 10.
- Transition level limits: TRL
- Transition level. Value range: 280 ... 10.
- Transition level limits: 850 .... 1100
-
QNH value. Value range: 850 ... 1100 hPa.
If the calculated QNH value is between the set limits, use the higher transition level value. If the calculated QNH value equals a set limit, use the lower transition level value.
You can use the same transition level value for multiple QNH ranges if the airport does not have 8 different transition levels. Alternatively, you can remove value pairs from the right side.
