2.13 Approved Launch Methods
Launching by Aerotow is approved using the towing release in the fuse-
lage nose. Winch and Autotow launches are approved using the tow-re-
lease below the rear seat.
The ASG 32 El is not approved for take-off by sole means of its own
power. Winch and Autotow launches have to be performed with the en-
gine retracted. Aerotows can be performed either with engine retracted
or with assistance by the own sustainer propulsion.
The flap settings 1 -3 are not permitted for Aerotow, Winch and Autotow
launches.
The maximum permissible launch speeds are:
aerotowing 180 km/h (97 kts, 111 mph)
winch launch 140 km/h (75 kts, 87 mph)
For winch launch, a weak link of 1000 daN ±10% (2248 lbs, black) must
be used with the launch cable or tow rope.
For Aero Tow, a weak link according to the tow plane must be used, not
stronger than 1000 daN ±10% (2248 lbs, black). Besides other regula-
tions which may exist, the tow rope must be a textile rope not less than
40 m = 130 ft or more than 60 m = 200 ft in length.
Weak link colours are not binding; this information refers to the colour
scheme of the Tost company.

3.8a
Emergency Retraction of the Power-plant
The following emergency retraction procedure can be applied, if the ex-
tended power-plant should fail and the additional drag is a serious danger
for the further flight. A still sound 12V power supply of the power-plant is
required for this.
WARNING
If the emergency procedure is applied, the propeller as well as the
engine compartment doors will be unavoidably severely damaged!
•Power-plant main switch: OFF
•Press and hold the turn-push button of the power-plant instru-
ment and switch power-plant main switch ON simultaneously
(service menu is shown)
•Press the turn-push button once and turn one notch clockwise
(field “retract” is activated)
•Press the turn-push button once (retraction starts)
•Wait approx. 10 seconds
•Press the turn-push button once (retraction stops)
•Power-plant main switch: OFF

Ground run
WARNING
Perform ground run with rigged aircraft only!
CAUTION
The freestream during flight is necessary for the proper air cooling
of the propulsion like it is the case during normal operation as sus-
tainer. The motor overheats after about 10 minutes ground run with
a power setting of 100% and 20°C (68°F) outside air temperature.
The operation limitations of this flight manual chapter 2.4 have to
be met anyway.
CHECKLIST: Extending propeller and starting motor
- Battery emergency stop: OFF (= not pushed; release by turning)
- Power-plant main switch: ON (power-plant instrument on)
- Power lever: EXTEND (until the noticeable stop
position)
- Observe correct extension process in the mirror, blue message
„PRESS Starter Button“ appears, propeller holds in vertical position
- Check power-plant instrument for warnings
- Propeller area: CLEAR
- Wheel brake: ENGAGE (fully extended airbrakes)
- Starter: ENGAGE
- Adjust power-setting at the power lever as desired
CHECKLIST: Stopping motor and retracting propelle
- Power lever: 0% (until the noticeable stop position)
- Observe braking and vertical alignment
- Power lever: RETRACT (bottommost)
- Observe correct retraction process in the mirror
- Power-plant main switch: OFF

Sustainer assisted aerotow
The electric propulsion can be used to assist the aerotow, e.g. in case of
short or wet airfields.
WARNING
The sustainer assisted aerotow is only permissible, if the aerotow
would be also possible without the assistance of the gliders sus-
tainer. The assistance serves to increase the safety margin only.
Referring to the ground roll and take-off distance as well as the
climb rate of the tow the same values as for the unassisted tow
apply.
WARNING
The state of charge of the propulsion battery has to be at least 70%
to guarantee a sufficient amount of energy for the tow.
The proper function of the electric propulsion has to be tested with
a ground run before the tow. An indicated power of at least 26 kW
as well as a speed of at least 2200 rpm have to be achieved with a
power setting of 100% while stationary. See also page 4.10a.
In general, all procedures and limits of the normal aerotow apply. In ad-
dition, the following has to be regarded:
- Recommended towing speed 100 – 120 km/h (54 – 65 kts,
62 – 75 mph), in case of towing speeds above 130 km/h (70 kts,
81 mph) the sustainer propulsion has no benefit anymore. Hence the
sustainer should be stopped and retracted according the checklist of
section 4.5.1 at a safe altitude in case of high towing speeds.
The following checklist provides a procedure for performing a sustainer
assisted aerotow.

CHECKLIST: Sustainer assisted aerotow
- Power-plant main switch: ON (power-plant instrument on)
- Power lever: EXTEND (until the noticeable stop
position)
- Observe correct extension process in the mirror, blue message
„PRESS Starter Button“ appears, propeller holds in vertical position
- Pre take-off check
- Trim: NEUTRAL
- Attach tow rope
- Wheel brake: ENGAGE (fully extended airbrakes)
- Propeller area: CLEAR
- Starter: ENGAGE, motor still holds position
- Power setting 50% (≈ half travel / 12 kW)
- Tighten towrope (clear for take-off)
- During roll-up: retract airbrakes, power setting 100%
- Proceed like a normal aerotow
CAUTION
If the power lever is set to 0% after a motor run, means pulled down
to the noticeable stop position, the propeller is held vertically by the
motor. If then power is set again, the starter has to be engaged
again to activate the motor run.
NOTE
The motor speed is limited at its maximum permissible value by the
power electronics. This means, the motor cannot be overrevved
even at high towing speeds.
Prepare together with the tow pilot how to proceed in case of an aborted
take-off respectively engine failure for the different phases of the take-off
prior to the tow. The local conditions of the airfield and weather have to
be taken into account.

4.20a
CAUTION
In case of a motor failure at the sailplane, a decrease in climb rate
of the tow up to 1.5 m/s (300 ft/min) has to be taken into account. If
necessary, the emergency retraction of the power-plant as per
page 3.8 could be applied to improve this situation.
No matter which kind of occurrence appears, Fly the aircraft first! This
means, control pitch and direction, check proper airspeed. The pilot of the
sailplane can apply the following standard procedures:
CHECKLIST: Aborted take-off sailplane rolling on ground
- Release tow rope
- Power lever all way down
- Engage wheel brake
- Change direction, if necessary
CHECKLIST: Aborted take-off sailplane landing straight
- Release tow rope
- Power lever all way down
- Extend airbrakes and perform a landing
- Change direction or perform a groundloop, if necessary
CHECKLIST: Aborted take-off sailplane climbing further solely
- Release tow rope
- Establish safe flight attitude and airspeed
- Perform a climb with VY
- Choose a traffic pattern, which guarantee a safe continuation of the
flight
