Sheghnan Airport (Shiveh) is an airport with the ICAO code OASN and the IATA code SGA. Country: Afghanistan. Nearest settlement listed in the database: Shiveh. OurAirports classifies it as a small airport. Its ICAO code starts with the OA prefix, which marks airports in Afghanistan. The four-letter code OASN is used in flight operations and weather reports, while the three-letter IATA code SGA is used for ticketing and baggage handling. The airport reference point sits at 37°29'52"N, 71°30'31"E, at an elevation of 6,700 ft (2,042 m) above sea level. The applicable time zone is Asia/Dushanbe.

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 the infobox on the English Wikipedia, Sheghnan Airport (Shiveh) has one runway: 16/34 - 803 m long (2,635 ft), unpaved surface.
No OurAirports data is available for this airport, so the figures above come from Wikipedia - a community-edited source that can be out of date. The infobox also gives no runway width. Treat these numbers as indicative and check the current AIP before flying.
The thresholds are oriented as follows: 16/34 on 160° and 340° 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 16/34 axis, wind from the west (around 250°) or from the east (around 70°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 160° or 340° 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 Sheghnan Airport (Shiveh) are published under the ICAO code OASN. 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 OASN 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 OASN, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The Asia/Dushanbe zone stays at GMT+05:00 year-round, so converting to local time is always the same shift.
The closest airports in the database, measured in a straight line from the reference point, are Khorog Airport (UTOD, 1 km), Ishkashim Airport (OAEM, 88 km), Yawan Airport (OAYW, 94 km). When no report is available for OASN, they usually give the best approximation of conditions in the area.
