Netheravon Airfield (Salisbury, Wiltshire) is an airport with the ICAO code EGDN. Country: United Kingdom. Nearest settlement listed in the database: Salisbury, Wiltshire. OurAirports classifies it as a small airport. Its ICAO code starts with the EG prefix, which marks airports in United Kingdom. No IATA code is assigned, which is typical for airports without scheduled traffic. The airport reference point sits at 51°14'50"N, 1°45'15"W, at an elevation of 456 ft (139 m) above sea level. The applicable time zone is Europe/London.

The course is derived from the runway designator (number × 10), not from a survey - the actual magnetic bearing can differ by a few degrees.
Declared distances (TORA, TODA, ASDA, LDA) are published in the national AIP - they are not part of this table.
According to OurAirports data (compiled from AIP and FAA sources), Netheravon Airfield (Salisbury, Wiltshire) has 2 runways: 04/22 - 640 m long (2,099 ft), grass surface; 11/29 - 1,092 m long (3,582 ft), grass surface.
The longest of them is 11/29, at 1,092 m.
All runways have a grass surface, which distinguishes this site from airports with a paved runway.
The thresholds are oriented as follows: 04/22 on 40° and 220° magnetic, 11/29 on 110° and 290° magnetic. A threshold designator is its magnetic heading divided by ten (ICAO Annex 14), so the runway axis can be read straight off the numbers.
For the 04/22 axis, wind from the south-east (around 130°) or from the north-west (around 310°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 40° or 220° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
Weather reports for Netheravon Airfield (Salisbury, Wiltshire) are published under the ICAO code EGDN. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.
The decoder breaks the EGDN report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.
Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for EGDN, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The Europe/London zone is GMT+00:00 in winter and GMT+01:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.
The closest airports in the database, measured in a straight line from the reference point, are Upavon Aerodrome (Pewsey, Wiltshire) (EGDJ, 5 km), MoD Boscombe Down (Salisbury, Wiltshire) (EGDM, 11 km), Thruxton Aerodrome (Andover, Hampshire) (EGHO, 11 km). When no report is available for EGDN, they usually give the best approximation of conditions in the area.
