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.
