ADF Flashcards
What are two primary functions of the ADF system regarding a Non Directional Beacon?
Detects the direction to an NDB and receives its audio identification
How is the direction to the NDB displayed in the cockpit?
Direction is shown on instruments using a bearing pointer
What frequency range does ADF system operates in?
190 to 1750 KHz
What type of signal does NDB ground station transmit, and how is it broadcast?
Transmits an Amplitude Modulated signal in a circular pattern in all directions
How are RF signals generated and used within the ADF system?
Radio energy induces RF signals in a combined loop and sense antenna, and the ADF receiver measures these signals to calculate the relative station bearing.
