CFDM in english

Each time you get a paramotor flight homologated, the distance in kilometer is added to your yearly score.
To get a flight homologated you need to use a GPS and provide trace data (any file format accepted).

The type of paramotor doesn't matter. Any paramotor is welcome : tandem, foot launch, trike.

The "championship" is the main challenge : every flight counts.
A team ranking is also established. Team = up to 4 pilots.
There is also a "cup" based on 3 longest flights of each pilot.

- No FAI triangles here. The distance that counts for ranking and homologation is the length of the corrected convex hull of your GPS trace.
Convex hull is very easy to understand : imagine a rubber band around your trace. This is the convex hull.
 Now substract the distance between your initial take-off and final landing and you get the corrected convex hull.



- As you guessed it, there is no need to land where the take-off took place (e.g. you don't need to close your track).
  For example, a straight flight can get homologated.

- Your corrected convex hull must exceed 40 km.

- We accept foreign pilots, but sorry guys, one point of the trace must be located on the french territory.

- Last but not least : you are allowed to land and take-off again within a range of 1000 m as many times as you want.
 In other words : refuelling is allowed.

- You don't need to register to any website, just send your trace by e-mail.

- Cool feature : CFDM calculates the average airspeed by extracting wind speed and direction from your flight data, as variometers do.
