Tag:airmark=beacon

Radio navigation beacons support the different radio aeronautical navigational systems that help pilots guide their aircraft during flight. These facilities are particularly useful during bad weather (like fog, or low cloud), and for flights operating under IFR.

Those include:

• NDB Non-Directional Beacon
• ILS Instrument landing system
• VOR VHF Omnidirectional Radio Range
• DVOR Doppler VHF Omnidirectional Radio Range
• DME Distance Measuring Equipment
• TACAN Tactical Air Navigation
• RSBN Radiotechnic System for Inner Navigation (ru: Радиотехническая Система Ближней Навигации)

For visual navigation systems use aeroway=navigationaid.

How to Map

Place a node at the location of the beacon, and tag with airmark=beacon.

Tagging

• airmark=beacon
  • beacon:type=* - see Examples section below
  • beacon:code=*
  • beacon:frequency=* - in MHz
  • beacon:channel=*
  • localizer=yes, glideslope=yes - additional tags to mark subtype of ILS beacon
• operator=*
• ele=*

Examples

Photo	Tags	beacon:type	Description
Glide path	airmark=beacon beacon:type=ILS beacon:frequency=* glideslope=yes	ILS	ILS glide path
Localizer	airmark=beacon beacon:type=ILS beacon:frequency=* localizer=yes	ILS	ILS localizer
Outer marker	airmark=beacon beacon:type=OM beacon:frequency=*	OM	Marker beacon
Middle marker	airmark=beacon beacon:type=MM beacon:frequency=*	MM

Radiotechnic System for Inner Navigation	airmark=beacon beacon:type=RSBN	RSBN	RSBN

Past usage

There was no clear standard of tagging various navigation aid systems in the past. Therefore our data consumers should expect to find these systems marked with any of these tags:

• aeroway=navigationaid
• aeroway=beacon
• beacon=airmark
• man_made=beacon
• radio_transponder=navaid (See Proposed features/Radio navigation aids)

Also the type of the system was often referenced by key type=*.

See also

• aeroway=navigationaid - for visual navigation aids
• man_made=beacon - often used as a complementary tag to this tag
