3.A2 NAVIGATION WITH PRECISION ROUTE
This is a time-limited task in which the pilot must fly a course of their choosing from a given array of turn points, with the objective either to collect as many turn points as possible, or to cover as much distance as possible within the time limit, whilst flying as accurately as possible in straight line legs between turn points.
The pilot must cross a start gate and finish gate for the task, and may also be required to pass particular intermediate gates during the task, as specified at the briefing. There are no pre-declaration elements. Unless otherwise briefed, pilots will perform a free launch from their designated deck.
After crossing FP, pilots will proceed to land. Unless otherwise briefed, they will perform a standard deck landing at their designated decks.
After landing they will secure their aircraft and take their loggers to the download office.
Landing out before passing the finish point of the course: 100% penalty
Landing out after passing the finish gate: no penalty.
Dp = (Nlog - NDp) / NDp
Np = (500 * (NBp/NBmax)) + (500 * (Dpmin/Dp))
Pilot score = 1000 * (Np / Npmax)
Where, according to briefing;
NBp = The number of turn points a pilot collects in the task.
NBmax = The maximum number of turn points collected in the task.
NBp = the distance flown by the pilot in the task as a straight line measured between the turn points collected.
NBMax = the maximum distance flown in the task.
NDp = the distance flown by the pilot in the task as a straight line measured between the turn points collected.
Nlog = the pilot’s GPS logged track length between the start and finish gates
Np = the value used for normalised scoring after adjustment for track error.
This task was designed for and tested in the British Open Paramotor Championship 2017. It is intended to provide an incentive for pilots to not to fly pure navigation (turn point hunt) tasks at full speed throughout, because even very slight deviations from the shortest possible course between the selected turn points are reflected highly in the scores. Pilots need to slow down in advance of each turn point so that they can be sure they leave it travelling in exactly the right direction. Any error in navigation that results in a dog-leg course correction will result in a big penalty so pilots must be 100% accurate with their navigation to the ideal straight line.
