The Shark 600 has been carefully designed to comply with the slow speed
regimes of the ultralight category as well as to be capable of very high
speed cruise and excellent maneuverability. The wing shape/profile and
sleek design mean that there is a wide range of pitch attitudes which will
be selected in every flight. The Shark 600 has excellent forward visibility
which means that selecting accurate pitch attitudes in combination with
accurate power settings provides very precise control of aircraft
performance. Much more than in lower performance aircraft types the
following “equation” is important and valuable:
POWER + ATTITUDE = PERFORMANCE
4.6.4 Propeller & engine RPM
The Shark 600 easily increases its speed during maneuvering.
Careful power management is required to avoid engine RPM
overrun. This is especially important for fixed pitch propellers but
as well for electric adjustable propeller due to their slow angle
movement. It takes about 12 seconds to change the blade angle
from minimum to maximum. Therefore, even at constant speed
mode it is recommended to reduce RPM during maneuvering and
work smoothly with the throttle.
Hydraulically controlled propellers do have the advantage to
change blade angle very fast, therefore the risk of engine overrun
is minimal.
