WARNING! Wing and propeller surfaces must be immaculately clean, dry and undamaged at
all times. As all airfoils are laminar any impact spots, bumps and even a dirty (incl. water, snow...)
surface may signicantly lower ight performance. Stall speed, takeo and landing runway
length, sink rates and fuel consumption increase, while climb rates, ceiling, lift-over-drag ratio
and endurance decrease. Some of the these are eected by as much as 30%!
Noise levels
Noise levels are measured from the ground. The aircraft at MTOM must y over the microphone at a
height of 150 meters (500 feet), exactly at VNE, with engine power needed to maintain horizontally
rightened ight. All versions of Sinus ultralight motorglider’ noise levels measured in such manner
have been ocially assessed to be below 65 dB.
