What is an NDB?

August, 9, 2020 by

A Non-Directional Radio Beacon (NDB) is a low or medium frequency radio beacon transmits non-directional signals whereby the pilot of an aircraft properly equipped can determine bearings and “home” to the station

The pilot, through the use of an Automatic Direction Finder, uses these signals in order to determine relative/magnetic bearing and therefore position. The entire system consists of the following:

  • Ground station
  • ADF receiver
  • Antenna:
    Loop Antenna (Magnetic Bearing from the airplane to the station)
    Sense Antenna (Directional Information)
    Bearing Indicator

This is the symbol used in Infinite Flight for an NDB.
