Q-Codes
| Code | Meaning |
|---|---|
| QNH | Atmospheric pressure at mean sea level (may be either a local, measured pressure or a regional forecast pressure (RPS)). When set on the altimeter it reads altitude. |
| QFE | Atmospheric pressure measured at the airport station. When set, the altimeter reads the height above the station. Not in common use. |
| QNE | Indicated altitude at the landing runway threshold when 1013.25 hPa or 29.92 inHg (atmospheric pressure at sea level in the International Standard Atmosphere) is set as altimeter setting. |
| (QFF) | Atmospheric pressure at a place, reduced to MSL using the actual temperature at the time of observation as the mean temperature. |
| Code | Meaning |
|---|---|
| QDM | Magnetic bearing to a station (DM...direction magnetic) |
| QDR | Magnetic bearing from a station (R...reciprocal) |
| QUJ | True bearing/track to a station |
