4.14 Slips
Executing a slip as a maneuver to loose altitude with the Sportstar is not as
effective as using the flaps to loose altitude, i.e. by setting them to Landing
position 2 – 50 degrees (Landing position 1 – 30 degrees is recommended
for a normal landing ).
During practice of slips it is recommended to climb to a sufficient altitude
(3000 ft), then choose a direction which you will try to keep during the slip,
pull the throttle lever back to reduce to idle, slow the airplane down to
below 70 KIAS, 130 km/h, 81 mph, fully extend the wing flaps (otherwise
the slip will be shallow), adjust longitudinal trim and go into the slip.
If you try to slip left i.e. left wing down, then gradually apply pressure to the
right pedal all the way to its stop and simultaneously move the aileron
control (control stick) to the left. Control surface deflections should be such
as to hold the direction of flight. During a slip to the left where there is full
application of the right rudder, a certain amount of left control stick
deflection is required to keep straight. So if you apply during a left slip a
decreased application of the left stick, the airplane will have a tendency to
yaw to the right and to keep the direction straight you will be required to
decrease the deflection of the right pedal or increase the deflection of the
control stick to the left.
If you are going to use a slip as a maneuver to loose height before landing
in spite of the recommendation to use flaps instead, then choose the slip
direction according to the wind direction i.e apply pressure to the downwind
rudder and simultaneously move the control stick into wind. Recover fro the
slip at 60-80 ft / 20-25 m above ground (a higher airspeed requires more
altitude) i.e. neutralize the hand and foot controls to maintain the required
heading and to eliminate wind drift.
There is a risk when slipping with a small fuel reserve, especially during a
long slip with some engine power, of engine failure due to fuel starvation,
because may gravitate during a slip to the outside of the fuel tank outlet.
The minimum trim speed with flaps fully extended lies between 49-54 KIAS,
90-100 km/h, 56-62 mph, so if you would slip in this configuration at a lower
speed the airplane may not be fully trimmable and you will feel a slight non-
balanced force, however it is easily correctable. If you would release the
control stick, then the airplane will drop the nose down and the airspeed will
start to increase very fast. (Do not exceed VFE 70 KIAS, 130 km/h, 81 mph
with extended flaps).
