What is ADF receiver?
An automatic direction finder (ADF) is a marine or aircraft radio-navigation instrument that automatically and continuously displays the relative bearing from the ship or aircraft to a suitable radio station.
How do you read the ADF in a rotatable compass card?
For rotatable compass card, it was a big step over the fixed card indicator. The pilot can rotate the compass card with the heading knob to display the aircraft MH ” straight up ” . Then the ADF needle will directly indicate the magnetic bearing to the NDB station.
What is an ADF in aircraft?
The Automatic Direction Finder (ADF) is an aircraft navigation product that automatically calculates the relative bearing of the aircraft to the radio station.
How does an ADF work?
The ADF works by using the electromagnetic properties of the signal produced by the beacon. Two antennae are required, which are known as the loop antenna and the sense antenna.
What is the purpose of ADF?
Description. Automatic direction finding (ADF) is an electronic aid to navigation that identifies the relative bearing of an aircraft from a radio beacon transmitting in the MF or LF bandwidth, such as an Non-Directional Beacon or commercial radio broadcast station.
How does a ADF work?
How do you find ADF?
There are 2 types of compass rose dials that can exist in the navigational unit. One is a fixed compass rose, called a “Fixed Card” ADF. Zero degrees is always shown on top of the card. The “Rotateable Card” ADF allows the compass rose card to be rotated.

What is the difference between VOR and ADF?
ADF is one of the earliest forms of air navigation systems based on ground-based non-directional beacons (NDBs). VOR is a short-range radio navigation system for aircrafts which came into effect after the World War II.
What is ADF and how does it work?
Automatic direction finding (ADF) is an electronic aid to navigation that identifies the relative bearing of an aircraft from a radio beacon transmitting in the MF or LF bandwidth, such as an Non-Directional Beacon or commercial radio broadcast station.
Is ADF required?
“An AFD is never required for an approach (though it’s not a bad idea to have one with which to slap your copilot to wake him up) but ADF is,” wrote reader Joe Steim.
