05 - Gates for microlights
1.13.4 GATES, TURNPOINTS AND MARKERS
Gates are normally a straight line 250m wide perpendicular to the briefed track.
Gates may be:
- Known gates. Their position and height to be crossed will be briefed.
- Hidden gates. The height to be kept along the sections of the course where they are situated will be briefed.
Proof of passing a gate and it's timing will be by Marshals report or GNSS flight recorder evidence, as briefed.
Control points may be: A geographical point, a ground marker, a landing marker or a kicking stick.
Control points may be:
- Known control (turn) points. Their position and description will be briefed.
- Hidden control points. The track along which they will be found and their description will be briefed.
Proof of reaching a control point may be:
- by the competitor recording the symbol and position on the declaration sheet.
- by a Marshal's report.
- by flight recorder evidence.
The precise requirements will be described in the Task Description.
This change was approved in the exact same form by the Microlight subcomittee last year. The Paramotor subcomittee did not approve this change, because of a different spirit of their navigation tasks.
I have modified this proposal to that it only affects Microlights now.
Gates in this form (actually even 300m to each side of the track, but most importantly on a natural line or an object!) were used at the European Microlight Championship in Hungary and the feedback was VERY positive!
For completeness, the reasoning from last year:
According to 5.7.3, the width of a gate has to be at least 2mm in the official map. Since the normal scales used to competitions of microlights are 1:200 000 or 1:250 000, the gate cannot be 250m, as that would only be around 1mm. By extending the gate 250m to each side, therefore making it 500m, it is 2mm wide on the 1:250 000 map.
The accuracy and time measurements should be done on a landmark, so that the pilot can find and can adjust his position and timing to it.
