Winch launch
(Only permissible with c/g tow release in place)
Maximum permitted launching speeds
V
W
= 150 km/h (81 kt, 93 mph)
For winch launching only the c/g tow release must be used.
Prior to take-off – with flaps to be at setting "+1" – set the elevator trim as follows:
•
Rearward c/g positions:
Knob fully forward
•
Intermediate c/g positions:
Knob forward to first quarter of its travel
•
Forward c/g positions:
Knob to the middle of its travel
As the cable tightens, apply the wheel brake gently (via the stick-mounted lever)
to prevent the aircraft from overrunning the winch cable.
Ground roll and lift-off are normal – there is no tendency to veer-off or to climb
excessively steeply on leaving the ground.
Depending on the load on the seat, the aircraft is lifted off with the control stick
almost fully pushed forward in the case of aft c/g positions and slightly pulled
back with the c/g in a forward position.
After climbing to a safe height, the transition into a typical steep winch launch
attitude is effected by pulling the control stick slightly further back.
At normal all-up masses, i.e. without water ballast, the launch speed should not
be less than 90 km/h (49 kt, 56 mph), and with water ballast not less than 100 to
115 km/h (54-62 kt, 62-71 mph).
Normal launch speed is about 100 to 110 km/h (54-59 kt, 62-68 mph), with water
ballast about 110 to 135 km/h (59-73 kt, 68-84 mph).
At the top of the launch the cable will normally back release automatically; the
cable release handle should, nevertheless, be pulled firmly several times to
ensure that the cable has actually gone.
