A cold front had passed during the night with thunderstorms and heavy rain. Next morning on the backside of the front, the weather turned out beautifully. On the board for this school flight was short field landing on soft ground, so perfect conditions at Ringsted airfield (EKRS). After landing and take-off we returned to Roskilde Airport (EKRK).
Grass runways can be quite unreliable when wet. They can be soft and slippery. During landing it can be difficult to break the aircraft, so it is important to land the aircraft right at the treshold to have as much runway available for stopping.
When taking off it is advised to perform a rolling start (without stop on the runway) to avoid getting stuck in the soft ground. The aircraft is pulled in the air very early (so early that the stall horn will sound). The aircraft is kept in the ground effect (just a couple of feets over ground) to build up airspeed before starting the climb.
All in all a fun exercise and for the first time I was rather pleased with this (third) landing in Ringsted, so things are improving.
