Definition
PENDY NDB is the proper name of a specific Non-Directional Beacon (NDB) navigational facility, used as an example in the Instrument Procedures Handbook to illustrate FAA naming conventions for navaids. NDB facility names are spoken and charted as the name followed by the facility type — in this case, 'PENDY' is the assigned name and 'NDB' identifies the facility class.
Plain English
PENDY NDB is the name of a particular ground-based radio beacon that pilots can navigate from. 'PENDY' is just its name (like a place name), and 'NDB' tells you what kind of navigation aid it is.
Context Anchor
Seen on instrument procedure charts and in procedure naming discussions, especially where a route, fix, or approach is identified by a navigation facility name.
Derivation
“Beacon” originally means a signal or marker used to guide people. “Nondirectional” means the beacon sends its signal out in all directions rather than along one narrow path. That helps explain why an aircraft can use the signal to find the direction to the station.
Why Pilots Care
Knowing how navaid names are constructed helps pilots correctly identify a facility on a chart, in a clearance, or on an approach plate. Mistaking the name portion for the facility type (or vice versa) can lead to tuning or briefing the wrong aid.
Intuition Check
Do not read “PENDY” as a command or procedure step. It is simply the assigned name of the beacon; “NDB” tells you what kind of navigation facility it is.
Example Sentence 1
The approach chart showed the initial fix overhead PENDY NDB, so the pilot tuned the ADF to receive its signal.
Example Sentence 2
Pilots tune the ADF to the PENDY NDB frequency to track inbound on the published course.
