Eiri KY PIK-20 E - Climb; Cruising

PIK-20 E Flight manual
5.14 Climb
Optimum speed for best rate of climb is
90 km/h (56 mph, 49 kts) for 370 kg weight and
100 km/h (62 mph, 54 kts) for 470 kg weight.
Both speeds are with neutral flaps. The power setting for maximum
continuous power is 6000 rpm at 100 km/h (62 mph, 54 kts). The best
rate of climb is achieved with the gear retracted.
The electric fuel pump can be turned off at the desired altitude. The
fuel consumption is about 1 l/h (0.26 gall U.S./h) greater when the
electric fuel pump is on.
For noise abatement over noise-sensitive areas, the pilot can choose
his climbing route so that the noise disturbance is minimized.
The route should, however, of course follow the Air Traffic Control
clearances and instructions.
If possible when taking account of obstacles and other circumstan 
ces, the power can be decreased below the maximum continuous
power to reduce noise.
The certificated noise level of PIK-20 E is 63.2 dB (A) in overflight at
300 m (1000 ft) with maximum continuous power 6000 rpm at 100
km/h. By using 5800 rpm at 100 km/h the noise is reduced to about 60
dB
(A).
5.15 Cruising
Cruising is normally performed with maximum continuous rotational
speed 6000 rpm. The maximum level speed is then 135 km/h (84 mph,
73 kts) and this corresponds to 75 % power. To lower the fuel con 
sumption the electric fuel pump should be off.
The maximum allowed speed with engine extended is 195 km/h (121
mph, 105 kts) and the engine rotational speed is then 6600 rpm when
the throttle is in idling position. The maximum allowed rotational speed
is 6800 rpm and this should not be exceeded.
Long throttle setting below 75 % power should be avoided in climb,
cruise
and glide for proper lubrication.
Longer glides with closed throttle must therefore be avoided.
Rpm settings which cause excessive vibrations should be avoided.
