As of FlightGear 2.4.0 you can request a tanker close to your current position, via the in-sim <tt>AI > Tanker Controls</tt> dialog.
As of FlightGear 2.4.0 you can request a tanker close to your current position, via the in-sim <tt>AI > Tanker Controls</tt> dialog. The tanker AI dialog allows you to select one of the appropriate tanker types, set the airspeed and the contact radius. The contact radius is a useful approximation of realism as it allows you to receive fuel based on your ability to hold position.  


As of FlightGear 2.11 the tanker AI dialog has been much expanded. It is now possible to select from different tanker types, set the airspeed of the tanker and most importantly set the contact radius which determines how close one neeeds to approach the contact point in order to receive fuel. This allows to set the level of realism, for beginners a wide radius is recommended, whereas for a realistic simulation just few meters are appropriate.
The AI tanker aircraft has a simplified flight model which isn't affected by the atmospheric simulation. This means that it can be hard to hold position in bad weather.


==== Scenarios ====
==== AI Scenarios ====
Like the [[aircraft carrier]]s, AAR is implemented as an AI scenario. Selecting these requires an extra command in the commandline (eg. <tt>--ai-scenario=refueling_demo_1</tt>, check <tt>[[$FG ROOT]]/AI/</tt> to see what scenarios are available), or selecting the corresponding scenario from the [[FlightGear Launch Control|launcher/FGRun]].
There are some AI scenarios that place a tanker aircraft at a specific position flying a predefined route. Generally these scenarios are less useful than the AI Tanker dialog. To use one of these scenarios it much first be activated from the AI Traffic and Scenario settings dialog (or in the command line).


The A4F, Lightning or T38 are special cases, as they should automatically load a scenario containing a tanker (without the need for extra commands).
Certain aircraft such as the A4F, Lightning or T38 automatically load a scenario containing a tanker.
 
Make sure that "AI models" are enabled and start at [[San Francisco International Airport]] (KSFO, the default airport). Depending on the scenario, you might see the tanker crossing overhead when the sim starts; if not, don't worry.
