See what your VOR is telling you.

Drag the airplane or either station. Tap the map to move the airplane. Map positions are schematic.

Radial = FROM the station. An airplane south of a VOR is on the 180° radial regardless of its heading. OBS selects a course; it never changes which radial the airplane is on.

TO/FROM is about the selected course. Centered with FROM means the selected course goes outward along the radial; centered with TO means it goes inward on the reciprocal course. Near 90° to the selected course, the indication is ambiguous and the flag is shown as OFF.

The CDI is a course pointer, not a steering command. Reverse sensing can happen when you fly the reciprocal heading while tracking a selected course. Match the course and intended direction before correcting.

Teaching simulator only. The display uses idealized geometry, a nominal ±10° full-scale VOR CDI, and no signal errors, cone of confusion, range, or real-world navigation data. Never use it for flight navigation.
