Data Sources

Aircraft data

Database filename

This is the full path to the SQLite database that either BaseStation or the Database Writer Plugin updates with information about the aircraft that it sees. You may leave this field blank but if you do then the reports will be empty and information that is not transmitted by the aircraft (such as the registration, the type of aircraft, the operator of the aircraft and so on) will not be displayed.

Flags folder

This is the full path to the directory that contains aircraft operator logo images. You can leave this blank but if you do then operator logos will not be displayed.

VRS looks in this folder for a BMP file whose name corresponds with the OperatorFlag field from the BaseStation database record for an aircraft. OperatorFlag is usually filled with the ICAO operator code by programs such as SBSPopulate.

Silhouettes folder

This is the full path to the directory that contains aircraft type silhouette images. You can leave this blank but if you do then silhouettes will not be displayed.

VRS looks in this folder for a BMP file whose name corresponds with the ICAOTypeCode field from the BaseStation database record for an aircraft. This is usually filled with the ICAO8643 code by programs such as SBSPopulate.

Pictures folder

This is the full path to the directory that contains airplane pictures. You can leave this blank but if you do then aircraft pictures will not be displayed.

VRS looks in this folder for files of type JPG, JPEG, PNG, GIF or BMP whose name is either the aircraft's ICAO identifier or registration (the ICAO takes precedence over the registration). The registration comes from the Registration field in the BaseStation database and the ICAO24 code comes from the message transmitted by the aircraft.

Search sub-folders for pictures

If this is ticked then VRS will look for aircraft pictures in the Pictures folder and all folders underneath it, otherwise it will just look in Pictures folder.

Download air pressure readings

If this is ticked then VRS will download the current air pressure readings for airports around the world every half an hour. Aircraft usually transmit a barometric altitude; the air pressure reading for the airport closest to the aircraft is used to calculate the aircraft's likely geometric altitude.

Aircraft fitted with ADS-B version 2 transponders are capable of transmitting the air pressure reading that they're currently using - when Virtual Radar Server detects these transmissions it always uses the aircraft's air pressure reading, it does not use the downloaded air pressure reading.

Aircraft details online lookup

Lookup aircraft details online

If this is ticked then VRS will lookup details about the aircraft that the aircraft does not transmit itself. The details that are looked up are:

  • Registration
  • Manufacturer
  • Model
  • Operator
  • Year of manufacture
  • Serial number

If you have configured a BaseStation.sqb then that is consulted for details about the aircraft, if the database has details then the lookup is not performed.
