QFE to QNH Calculator
Convert QFE (field pressure) to QNH (sea level pressure) using airfield elevation.
- Enter QFE in inches Hg, hPa, or mbar
- Enter airfield elevation in feet or meters
- Results show QNH in all common units
Navigation Database
Search and access information for:
- Airfields (with runway, ILS, and ATC information)
- Navigation Points
- Beacons (with frequencies)
- Towns and Reference Points
Flight Log System
Plan and track your flight route:
- Add waypoints from the database
- Record navigation points and frequencies
- Export/Import flight plans
- Maximum usable flight level: FL350
Important Notes
- All elevations are in feet MSL (Mean Sea Level)
- Frequencies are shown in MHz
- Coordinates are in decimal degrees
- Flight levels should be entered in hundreds of feet (e.g., 250 for FL250)
