Free VOR & NDB Radio Navigation Simulator
Practise aviation radio navigation in your browser — no account required. Fly with a realistic HSI (Horizontal Situation Indicator), VOR CDI/OBS, and NDB/ADF instruments on a live moving map with real wind simulation.
What you can practise
- VOR tracking — tune a VOR frequency and track inbound or outbound radials with CDI and OBS
- NDB / ADF navigation — follow NDB bearings using the ADF needle
- HSI instrument reading — interpret course deviation, TO/FROM flag, and heading bug
- Wind correction — apply heading offsets to maintain a desired ground track
- Time acceleration — speed up the simulation up to 12× to practise faster
Instruments included
- HSI — heading bug, course deviation indicator, TO/FROM flag
- CDI / OBS — standard VOR course deviation indicator
- ADF needle — NDB bearing pointer
- Moving map — aircraft position, navaid stations, range rings, wind vector
