7.5 NDB Navigation

7.5.1 Generally, when flying to a NDB, make sure the arrow points upward, as seen in the middle picture. This means you are flying directly to the beacon.

 

 

 

 

 

 

 

 

 

7.5.2 When flying from a NDB, keep the arrow pointing down. You will be flying a QDR from the beacon.

7.5.3 The ADF has a compass card that can only be turned by rotating the ADF knob. This is just so that the pilot can orientate him/her self.

 

 

 

 

 

7.5.4 When flying cross-countries, NDB’s can be used to cross check your position, for instance:

7.5.5 You can pinpoint your position on the map by measuring the relative bearings of 2 NDB’s. If the bearings were 270 and 015 respectively, the aircraft will most likely be at position X.

 

 

 

 

 

 

7.5.6 NDB’s can also be used to find out time and distance to the beacon.
