technique is to hold full rudder but not to ride the brake
continuously. Apply brake inter-mittently and allow the aircraft to
accelerate between ap-plications. The takeoff ground roll can be
extended significantly (50% or more) by strong crosswind,
especially at high density altitudes and high gross weights. The
braking requirement for directional control is the reason for the
takeoff limitation of 15 knots crosswind. Landings can be made
up to a 20-knot crosswind component.
CROSSWIND TAKEOFF TECHNIQUE: Hold aileron into the
wind as you rotate for lift off. Let the aircraft accelerate above
normal rotation speed and then rotate the nose abruptly to make
a clean lift off without side-skip. For crosswind components
above 10 knots, add 5 knots plus one half the gust factor to the
normal rotation speed. When clear of the ground, make a
coordinated turn into the wind to correct for drift and to main-tain
a straight track over the runway.
SHORT FIELD OBSTACLE CLEARANCE
Reduce gross weight, as much as feasible and check the c.g. to
insure it is not so far forward as to delay rotation. Be sure the
engine is thoroughly warmed up and taxi to the very end of the
rummy. Make sure the fuel selector valve is fully open. Align the
aircraft with the runway, hold the brakes, and apply full power.
Release the brakes and try to use minimum braking for
directional control. Rotate to lift-off at 56 knots (light weight) or
65 knots (heavy weight). Maintain 70 knots (80 mph), best angle
of climb speed, until the obstacle is cleared, then accelerate to
normal climb speed. See the “Takeoff Distances” section of this
manual.
ROUGH FIELD CAUTION
Although the COZY uses 500 x 5 tires and a spring loaded shock
strut, this does not make the aircraft totally suited to rough,
gravel, or unprepared fields. Since the COZY is a pusher, it
cannot be rotated as easily as tractor type aircraft, which have a
prop blast across the tail. You still must accelerate to normal
rotation speed 50 - 60 knots; depending on c.g., before the
nosewheel comes off and during this time the nosewheel can
kick debris into the prop. The small nose wheel tire, high
ro-tation speed, and possible prop damage makes the COZY
less suitable for unprepared field operation than low performance
tractor types.
However, if you must use an unprepared surface, reduce gross
