5. Performance
Section 5 provides data for airspeed calibration, stall speeds and take-off, landing and other
data. The data in the charts has been computed from actual flight tests with the aeroplane and
engine in good condition and using average piloting techniques.
The flight and operational characteristics of the STOL CH 701 are normal in all respects.
There are no
“unconventional” characteristics or operations that need to be mastered.
All the controls respond in a usual way within the entire range of operations of the
airplane.
Speeds provided are indicate airspeed (IAS), unless specified otherwise.
Pitot must be in correct position
static - cabin static pressure
True airspeed = IAS +/- 5 kt in normal operations
Performances are given in
standard
atmosphere.
Aircraft and, powerplant in new
condition with standard equipment.
Stall speed
(at gross weight 45 kg):
Flaps Up
31 kt
Flaps Down
27
kt
- the above speeds are with engine at idle, the aircraft simply “mushes in” at stall. The
airplane has a relatively high sink rate with flaps fully lowered.
- With power, the indicated stall speed is bellow any accurate indication as nose attitude
is very high. Stall occurs around a walking, speed preceded by substantial buffet. The nose
drops fast.
CAUTION:
Maximum flaps extended speed VF = 55 kt

- take off distances from grass fields are longer and depend on the actual surface.
Landing distances:
Landing distance over 15 m. obctacle is 283 ft (ground roll 180 ft)
