Descent and final approach
Descend at speeds at or below VNO with the flaps retracted (0
o
)
For approach reduce speed to 70 kts (130 km/h) and extend flaps to 15
o
only after turning to base leg.
Adjust motor power to maintain proper airspeed. Set the trim to neutralise stick force if necessary.
During the descent, monitor temperatures and keep them within operational limits.
CAUTION! With power lever set close to cut off, the motor will recuperate energy during the
descent and the vertical sink speed will increase, similar to the effects of airbrakes on sailplanes.
On final, reduce speed to 60 kts (111 km/h) and extend flaps to 25
o
.
Align the aircraft with the runway and reduce power to cut off.
Maintain an airspeed of 56 kts (104 km/h).
Use the power lever to control your descent glide path. Control your attitude and crab if necessary.
CAUTION! Crosswind landings require higher final approach speeds to ensure safe maneu-
vrability. Increase the approach speed by 1 kts for every 1 kts of crosswind component e.g. If
there’s a crosswind component of 5 kts, increase the approach speed by 5 kts.
Roundout and touchdown
CAUTION! See chapter “Performance” for landing performance.
Roundout and touchdown (flare) occurs at following airspeeds:
Calm air, aircraft at MTOW 40 kts (75 km/h) IAS
Rough air, aircraft at MTOW (incl. strong crosswinds up to 18 kts (34 km/h)
of lateral component)
42 kts (78 km/h) IAS
CAUTION! Land the aircraft in such a manner that the two main wheels touch the ground
first, allow the nose-wheel touchdown only after speed has been reduced below 25 kts. When
lowering the nose wheel to the runway the rudder MUST NOT be deflected in any direction
(rudder pedals centered).
When on the ground, start the braking action while holding the control stick in full back position.
Steer the aircraft using the rudder only. If the runway length is sufficient, come to a complete standstill
without engaging the brakes, while holding the control stick slightly backwards as you slow down.
