It is recommended to make full circuits to have enough time to configure the aircraft for landing.
Slow down when in downwind till 130 km/h. You then can lower the flaps to 20 degrees. Slow
further down below 110 km/h for higher flap setting, if needed.
Land the aircraft with 20 degrees flaps in gusty or cross winds. Full flaps for short runways. In
other cases use the flaps depending on the necessity.
Fly the straight final at 1.3 V
S
being approx.110 km/h pending the gross weight of the aircraft.
Don’t forget “an aircraft ALWAYS stalls at the same ANGLE OF ATTACK, never at the
same speed”
Increase speed with 10%, when flying in rain.
Bear in mind, that the DRAG increases with the flap setting and that you have to adjust power
settings accordingly to avoid too pronounced descent rates.
In gusty wind conditions it is recommended to adapt your approach speed in regard to the value
of the gust difference.
Make the difference between gust and steady wind velocity, divide by two and add this value to
your approach speed.
Wind
260/15 km/h
Gust
260/25 km/h
Difference
25 km/h – 15 km/h = 10 km/h
Divide by two
10 km/h : 2 = 5 km/h
Approach
95 km/h + 5 km/h = 100 km/h
