Scoring

All Scoring and flight validation is via officially issued systems with backup logs from pilots personal instruments.
See PWCA rules regs and scoring parameters as per PWCA RULES

 

GPS Software

The GPS software used by the PWCA is CompCheck® (designed by Ulric Jessop)
The software is able to check positions in relation with times.
The software is also able to check:

  • Departure time during starts
  • Cylinder crossing for air start and turn points
  • Landing place
  • Arrival Time
  • The best position reached by the pilot during the flight
  • Best positions at a fixed time (when stopping a task in the air)
  • Airspace infringements
  • Reserve deployments

 

PWCA Scoring Formula
The following text describes the scoring formula used in PWC events. It is generally referred to as the “PWC 2016” formula.

C.1 General
The PWC 2016 scoring formula is based on GAP 2002, as used by CIVL and in most
competitions run worldwide, but with some important modifications:

  1. PWC 2016’s Arrival Points depends on the goal configuration.

    a. If the End of Speed Section is before the goal, then no Arrival Points are awarded.
        Instead, the allocation goes to time-points.
    b. If the End of Speed Section is at the goal, then Altitude Arrival Points are awarded.
        These have the same allocation as traditional Arrival Points, but reward pilots who arrive
        high in goal.   
     
  2. The Leading Points calculation is altered so that leading out early in the taskgives more Leading Points compared to GAP 2002.
     
  3. The Launch Validity calculation is altered so that if a small number of pilots do not take off, Day Quality will still be 1.
     
  4. The handling of stopped tasks, especially the calculation of the Day Quality in a stopped task, is done differently. 
    The details of these changes are given below in their respective sections.

What is kept in PWC 2016 is GAP’s general idea:

  1. For every event, a set of scoring parameters is defined, to reflect the expected kind of tasks to be flown during the event.
     
  2. For every task, based on the scoring parameters and the pilots’ actual performance, a Day Quality is calculated. This factor defines the maximum number of points awarded in that task.
     
  3. Points are awarded to a pilot in four categories: Distance Points, Speed Points, Leading Points, and Arrival Altitude Points. A pilot’s task score is calculated by adding up these four values.
