Russian airfield database
©2009 Tim Vasquez

Name.  The most popular recognized name for the airfield is assigned.<br><br>

Alternate names.  Alternate names exist for many airfields.  The sources consist of alternate local names, alternate Romanizations, and names given by American intelligence sources during the Cold War when the airfield name was not known.

Reference.  A reference to the closest town is listed in kilometers and directions relative to true north.

Oblast.  The oblast name is listed, if known.

Country.  The country name used today is listed in ISO-3166-1 alpha-2 format.  Russia is RU.  Older codes such as SU (Soviet Union) are not used.

Image Quality.  The image quality used to assess the airfield is ranked from 1 to 9.

ICAO.  The English ICAO assignment is given here as given in ICAO Doc 7910.

ICAOR.  The non-standard( Russian) ICAO assignment is given here.  These are Romanized transliterations of the Cyrillic identifier based on standard letter-for-letter Baudot/KOI-8 code conversions.  Identifiers given here are defined internally by the ex-CIS states and are assigned according to some sort of internal Soviet/Russian standard that I have not been able to obtain any information on.

ICAO source.  The ICAO source is provided here according to Table 1 below.

Category.  The category of airfield is provided here:
	M	Major
	N	Minor
	A	Abandoned
	X	Unknown

Significance.  The significance of the airfield according to apparent volume, infrastructure, and capacity, is ranked 1 to 9.
	0  Airfield abandoned or clearly unused
	1  Small airfield, neglected, unattended, location almost invisible in satellite photos
	2  Small unattended airfield
	3  Small airfield with structures on-site
	4  Medium airfield, possibly with passenger terminal
	5  Medium airfield, some possibility of a control tower
	6  Large airfield, control tower likely
	7  Large airfield, hangars, control tower likely
	8  Large airfield, large infrastructure, hangars, control tower
	9  Very significant facility, vast infrastructure, hangars, control tower

Latitude/longitude.  The latitude and longitude are provided in dd mm.m and dd.dddd format.  The position is determined by establishing an ARP (Airfield Reference Point).  For the purposes of this database, the ARP is always the centerpoint of the major runway (major runways do not include grass strips and minor runways).  For airports which have two or more major runways, a reference point is calculated for each major runway and these are averaged together.  The ARP may differ from Jeppesen and CAICA values, but will be similar.

Latitude/longitude source.  The source for latitude/longitude is coded according to Table 1 below.

Elevation.  An elevation value in feet and elevation source are provided, with the source coded according to Table 1.  There are provisions for 3 sets of elevation data.  The one believed to be most accurate is listed in the leftmost column.

Magnetic declination.  Magnetic declination is provided referenced to 2010.

Runway data:
	Length			Meters
	Width			Published or marked width
	Pavement width		Full width of pavement, as originally built
	Source of dimensions	Source of runway dimension data (see Table 1)
	Overrun 1		Overrun length at the end of the runway (most northeasterly or southeasterly edge)
	Overrun 2		Overrun length at the end of the runway (most southwesterly or northwesterly edge)
	Name			Name of runway
	Surface			Surface type

Use of airfield.  Indicates the use of the airfield: MIL (military), CIV (civilian), or MIL/CIV (military/civil) with the most significant use ordered first.

Operator.  Operator of the airfield, if known.  For military airfields this is usually the Air Force branch in charge of the airfield (PVO, OGA, etc).

Military purpose of airfield.  This indicates all major uses of the airfield during the Cold War and post-USSR years.  The codes loosely match that in the American military aircraft nomenclature system.
	A 	Attack
	B	Bomber
	F	Fighter
	G	Highway strip
	H	Helicopter
	I	Interceptor
	R	Reconnaissance
	Y	Dispersal airfield
	Z	Abandoned
	
Units.  Military units based at airfield, with years and comments.

Notes.  Comments, notes, and remarks about the airfield.
