VOR Errors Quiz and Flashcards for Mastery

Study Notes

VOR Overview

VOR stands for Very High Frequency Omni-Directional Range, a type of radio navigation system.
Utilizes radio signals to determine aircraft position and assist in navigation.

Instrumentation

VOR systems include a Course Deviation Indicator (CDI) to indicate the aircraft's position relative to the desired course.
Each notch on the VOR face represents 2 degrees of heading.

The CDI instrument indicates whether to fly to or from the VOR station; the standard operation is "To."

Error Types

Ground Station Error relates to misalignments or inaccuracies based on the physical location of the VOR station.
Site Effect Error is influenced by the station's topographical setting, affecting signal quality.
Terrain Effect occurs when the signal is reflected by terrain, resulting in interference or distortion known as a rippling effect.

Equipment Issues

Airborne Equipment Error refers to problems with the aircraft's receiver impacting navigation accuracy.
Vertical Polarisation describes the phenomenon where signals from the VOR hit the terrain and become vertical.
VOR signals are primarily transmitted horizontally, not vertically.

Signal Characteristics

Scalloping refers to the oscillation of the VOR signal from side to side horizontally, which could affect navigation messages.
Aggregate Error is the total accumulation of all individual errors impacting the accuracy of the VOR signal.
