4.4  NORMAL  OPERATIONS AND RECOMMENDED SPEEDS

4.4.1 TAKE-OFF AND CLIMB

1. Aerotow launching

The take-off technique by aerotow is entirely conventional. The elevator
and rudder efficiency is high enough during the initial stages of the
take-off run, that it is easy to prevent directional or roll oscillations by
use of rudder or ailerons, Set the elevator trim tab control to a position
between  “zero”  and  “nose  heavy” and hold the control stick in the neutral
position 

on the landing gear and at liftoff speed pull the control stick

gently to unstick the sailplane. Hold the sailplane in horizontal flight at
a height of 3 ft (1

 

m ) until the towing airplane starts to climb. The take-off

with cross wind is different from the normal take-off. It is necessary to
bank the wing into the wind ( in proportion to the wind speed) and to
unstick the sailplane at a higher speed. The tow rope should be attached

to the front hook only.

Note:

Before take-off close the ventilation in order that dust and

impurities do not get into the cockpit. The ventilation can be
opened during at climb.

2.Winch-launching

WARNING:

U S E   E I T H E R   S I D E   H O O K S   O R   L O W E R   H O O K
(DEPENDING ON WHICH HOOK IS INSTALLED)

The winch launching is entirely conventional. Set the elevator trim tab

control to the neutral position. The recommended speed for winch
lauching  is 43 - 54 KIAS. Do not retract the landing gear when performing

the traffic pattern.

3.Aerotow

a)Climb

Retract and lock the landing gear (by pulling the handle in your

direction) when above  a minimum

 safe height of 66 ft and the minimum

speed of 54 KIAS is reached. Trim the sailplane for the  climb speed. The
sailplane angle of attack is fairly high when the climb speed is low and
