This add-on add a new item to main menu named `Aerotow Everywhere` with following items:
1. `Aerotow Route` - display the dialog for change aerotow route.
2. `Call for Piper J3 Cub aircraft` - load AI tow sceneraio with Piper J3 Cub.
3. `Call for Robin DR400 aircraft` - load AI tow sceneraio with Robin DR400. This aircraft has better performance and can take you higher then Piper Cub.
4. `Call for Cessna 182 aircraft` - load AI tow sceneraio with Cessna 182. This aircraft has little bit better performance than Robin.
5. `Disable tow aircraft` - unload AI tow sceneraio.
6. `Add thermal` - display the dialog for configuring and adding thermal.
7. `Help` - display help dialog.
8. `About` - display about dialog with add-on information.
2. `Towrope Configuration` - display the dialog for change towrope parameters.

On the top of the "Aerotow Route" dialog you have selector to change aircraft type. It's only for calculate performance and display how the altitude will change.
### Max alt (AGL)
Here you can set limit of AGL altitude. 0 means without limits - the plane will always increase its altitude during its flight. AGL is always in terms of the place you are starting from.
### Route
Next you have initial heading, distance and altitude change. "Initial heading" depend of the runway where you are located. The aircraft will always take-off along the runway, a distance of 100 m, where it will gain 20 ft in altitude above the terrain. These parameters you cannot change unless you change the airport/runway.

1. `Heading change (deg)` - information on how the heading of the aircraft should change in relation to the previous one. A value of `0` means no change, so continue with the same heading. And e.g. `-90` means a left turn of 90 degrees, `60` means a right turn of 60 degrees, etc.
2. `Distance (m)` - distance in meters from the previous waypoint to the present one.
3. `Alt change (AGL ft)` - information on how much the altitude on this leg of the route will increase (in feet above ground.) This information depend of selected airplane.
3. `Alt change (AGL ft)` - information on how much the altitude on this leg of the route will increase (in feet above ground.) This information depend of selected airplane. AGL is always in terms of the place you are starting from (not the waypoint place).
If you enter a value less than or equal to `0` for `Distance (m)` field this means that here the route is end and the next rows will not be included to the flight plan.
