Γιάννη δες
το νέο κανονισμό F4 2009 από το site της FAI.
Εύλογη η απορία σου, η διαφορά είναι στο ύψος,
η προαιρετική άσκηση (το γράφει και στα ελληνικά) έχει ύ
ψος πτήσης έως το πολύ 6m, δηλαδή στην ουσία είναι
χαμηλό πέρασμα.
Από τον νέο κανονισμό 2009
6C.3.6.2. Straight Flight:
Model aircraft should make a straight and level flight of at least 100 metres length centred on the judges’ position.
Errors:
1. Not a straight course (slight corrections are acceptable with a light aircraft)
2. Not constant height.
3. Not pass over the landing area.
4. Not centred on judges’ position.
5. Not parallel with the judges’ line.
6. Too short a distance (too long is not an error).
7. Model aircraft flight path not smooth and steady.
8. Too far away, too close, too high, too low.
T Flight in a Straight Line at Constant Height (Maximum 6 m):Model aircraft approaches in straight flight at a constant height not exceeding 6 metres for a minimum distance of 100 metres, then climbs away. This is in effect a low flypast.
Errors:
1. Not a straight course (slight corrections acceptable with light aircraft).
2. Not constant height.
3. Not 6 metres or below.
4. Not pass over the landing area.
5. Not centred on judges’ position.
6. Not parallel with the judges’ line.
7. Too short distance (too long is not an error).
8. Model aircraft flight path not steady.
9. Too far away/too close/too high/too low.
Ελπίζω να μην παρεξηγηθώ, κριτής F3A έχω κάνει, όχι scale.
