S10 4.24.5
Annex 4, 2.A1, 2.A2, 2.A3, 2.A4, 2.A5, 2.B1
Backtracking is defined as flying with an angle of greater than 90 degrees, when the flight data recording shows this deviation for more than 5 seconds in sequence, in respect to the intended flight direction within a corridor defined by the width used to score gates in the task.
Reason
According to the current rules, even one second of the unintentional backtrack can bring a 100% penalty to the competitor. Losing the full number of points for a task is very harsh and will make a favourable overall result impossible. It results in loss of interest in microlight competitions. In order to attract new competitors, it will be better to change the definition, create a pillow for inaccuracy (like for +-5 time on ground speed, 50ft height of logger error).
