weight as much as feasible and adjust the c.g. as far aft as
practical (within limits) to allow an early rotation. Do not use high
power with the aircraft stationary, do the mag check on the roll if
necessary. Hold full aft stick and apply power gradually to start
the aircraft moving before coming in with full power. This
technique will help minimize prop damage. As the nose raises,
the elevator should be eased forward so the nosewbeel is held
just clear of the ground. Accelerate and lift-off at the normal
speed and accelerate to the desired climb speed. Don't try to
"jerk" the aircraft off prematurely; this only places the prop closer
to the ground and increases the chance of damage.
Operation from grass fields, even if smooth, is not
recommended. The additional rolling resistance will extend the
takeoff roll. Even with 500 x 5 tires and the shock strut, most
grass fields will punish the gear more than hard-surfaced
runways.
HIGH DENSITY ALTITUDE
At density altitudes above 5000 ft., follow the normal takeoff
procedures except (1) lean the engine for best power during run
up and (2) let the aircraft accelerate to 65 - 70 knots (75 - 80
mph), and then · smoothly rotate and lift off.
CLIMB
Climb performance data is given in the “Climb Speeds” section of
this manual. For optimum rate of climb, maintain 90 knots (105
mph). Best angle of climb is obtained at 70 knots (80 mph). For
better visibility and improved cooling, a normal cruise climb of
110 knots (125 mph) is used. Climb performance is improved
with the nose gear re-tracted, although not drastically, and it
should be retracted once your initial climb is established.
CAUTION
The altitude capability of the COZY far exceeds the physiological
capability of the pilot. Use oxygen above 12,500 ft.
CRUISE
Maximum recommended cruise power setting is 75%. A high
cruise power setting (full throttle at 8,000 ft. density altitude will
result in the maximum true cruise speed of 161 knots (185 mph)
for a 118 hp Lycoming engine and a RPM slightly over rated.
