This is the lite HD version of Radionav Sim, the ADF, RBI, RMI, VOR and HSI simulator. This is a must for CFI and CFII teaching how to read the instruments. Drag the aircraft and the beacon on the map, and observe the reactions of the instruments.
You can also draw a trajectory and the aircraft will fly it, with the instruments being updated in real time. Holdings, radial interceptions and station crossings will have no mystery anymore!
