Precision Approach Radar (PAR) is a ground instrument conceived primarily to provide the GCA service.
 |
Work in progress This article or section will be worked on in the upcoming hours or days. Note: Although still incomplete, the information it contains is valid and available. See history for the latest developments. |
PAR allows the Ground Controlled Approach (GCA) controller to deliver approach directives to the requesting aircraft.
(see Howto:Implementing_a_simple_GCA_system)

Is there any work on GCA (ground controlled approach) in progress, or have missed it? GCA is surprisingly accurate and easy to use, both as a pilot and a controller. |

What can you expect from GCA
Arriving in the vicinity of the airport with little or no visibility, the pilot can request the GCA service. The Controller, assisted by a PAR (Precision Approach Radar), will guide you through a safe path (both in heading and in altitude) that will take you to the head of the used runway.
How to install
{{note | This is the latest version (Feb 22, 2018)
If your FGFS version accepts Addons, you can download this feature from the Addons Repository. Download all the 12 files into the directory of your choice.
Launch FlightGear including --addon argument, eg.:
fgfs <usual args> --addon=/path/to/PARaddon/| Note From version 2017.4.0, the FG launcher accepts the --addon option in his Settings/Additional Settings tab. |
Otherwise, you can install it as a submodule. Contact the author for further instructions.
And that's all !
