@@ -24,6 +24,8 @@ Start FlightGear at any airport with your aircraft as a glider, such as ASK 21.
From the top menu, select `Aerotow Everywhere` -> `Call for Piper J3 Cub aircraft`, `Robin DR400` or `Cessna 182` (yes, you can choose from many aircrafts). The AI aircraft will appear to your right and align to the centreline of the runway in front of you. At this time you should hook up to the aircraft, most often by pressing the `Ctrl-o` key (check help of your glider). The AI aircraft will begin to accelerate and take off.
You can also take off in the bush. Then the tow plane will position itself in front of you (glider's course), so what heading you have is important. If you move away from the runway threshold further than 100 m, then the take-off of the tow plane will be as in the bush, i.e. according to the glider heading and not the runway.
## How does the AI tow aircraft fly by default?
The tow plane always takes off in front of your runway and flies along the runway for 5 km, then turns back and flies downwind for 6 km, then turns back again and flies another 6 km. During this flight it is constantly gaining altitude. Then when it has completed the entire set route it turns to unknown direction and flies at a constant altitude.
