NDB Radio Navigation
NDB stands for Non Directional Beacon.
NDB/ADF errors
Electrical interference. Radio waves are emitted by the aircraft alternator in the frequency band of the ADF.
NDB - non-directional beacon. A medium-frequency navigational aid which transmits non-directional signals, superimposed with a Morse code identifier and received by an aircraft's ADF.
nm - nautical mile(s).
NDB. See nondirectional radio beacon.
NM. Nautical mile.
NOAA. National Oceanic and Atmospheric Administration.
NDB & ADF
Non-directional radio beacons (NDBs) are simple AM radio transmitters that were first deployed in the 1920s and '30s along major airmail routes.
NDB - Non-Directional Beacon. An LF, MF, or UHF radio beacon transmitting non-directional signals whereby the pilot of an aircraft equipped with direction finding equipment can determine his bearing to or from the radio beacon and "home" on or ...

VOR, ILS, NDB, VASI, DME, MLS, are different navigation aids and need periodic flight inspection.

Non-directional beacons (NDB) are another from of NAVAID used but these are more so for approaches. Really popular in the mid 1900s, they were more or less phased out for navigation by the VOR.
VOR and NDB stations, provided they are not directly behind or ahead of you, can also provide progress information. To make use of this information, draw on your map. The navigation receiver will tell you what radial you're on ...
In the United States, an NDB is often combined with the outer marker beacon in the ILS approach (called a Locator Outer Marker, or LOM); in Canada, low-powered NDBs have replaced marker beacons entirely.

MOGAS: motor gasoline (as distinct from AVGAS). NDB: non-directional radio beacon.
nm: nautical mile(s).
NOTAM: Notice to Airmen.
A companion receiver in the airplane provides an indicator that shows the direction from the station to the airplane. This is somewhat simpler to use than an NDB because the indication is independent of which way the airplane is pointed or moving.
ADF uses AM radio signals. A needle on the instrument points in the direction from which the signal originates. The instrument is usually used with NDB's, but can also be used with commercial AM broadcast radio signals.
