A VOR flight instructional aid and methods for its use are described herein. Said instructional aid comprises a base, a course indicator arm pivotably connected to said base, and a physical representation of an aircraft connected to the end of the course indicator arm. Said instructional aid may further comprise an OBS/CDI indicator disk pivotably connected to the base for illustrating the approximate appearance of a CDI display resulting from various combinations of aircraft position and OBS setting. Said instructional aid may be used by: 1) placing the base on a flight navigation chart; 2) substantially aligning the pivot point of the course indicator arm above the position of the desired VOR station on the chart; and 3) rotating the course indicator arm to an OBS-selected radial, thereby physically representing the aircraft position relative to the VOR station. Further steps may include rotating the OBS/CDI indicator disk to an OBS-selected radial, and noting the resulting approximate CDI needle appearance physically and graphically represented by the position of the course indicator arm relative to the OBS/CDI indicator disk.
