towing rope and stop the action. c) If the rope is self-released just after lift-up of the towing aircraft, the aircraft will continue the flight. d) In case of engine power lost or another failure which disables to continue take- off just after lift-up of the towing aircraft, the pilot of towing aircraft will release the rope immediately and make emergency landing with respect to failure character. e) Forced landing of towing aircraft with towing rope attached is prohibited (except emergency situations). Amendment to Flight and Operations Manual of ATEC 321 Faeta UL aircraft - Aerotow ATEC v.o.s. Libice nad Cidlinou, Czech Republic Page 5 of 8 f) In case the pilot of towed glider does not release the towing rope even after repeated signal, the pilot of towing aircraft will release the glider when overfly the aerodrome. g) When, after many attempts, the towing rope is not possible to release by the towing aircraft or by the glider, even the rope is not possible to cut, the landing of towing aircraft must be made together with towed glider connected. The pilot of towing aircraft will gradually descend and approach with respect to glider´s abilities. After landing, the pilot of towing aircraft must keep an adequate engine run to keep enough distance from the glider. h) In case of insoluble emergency situation, it is possible to use the rescue system (if equipped with). Before its activation, the pilots of both glider and aircraft must release the towing rope. i) Attentively check and follow all flight and engine values and limits during aerotow! 1.7 Normal procedures Before aerotow starts, the pilot of towing aircraft must be aware of glider´s take-off methodics and operation limits as described in appropriate glider´s flight and operations manual. a) Before start up, all procedures described in Flight and Operations Manual of ATEC 321 Faeta must be followed same way as before usual flight. b) Both, towing aircraft and towed glider must be positioned in the same take-off axis before the aerotow starts. c) First, the towing rope is attached to the towing aircraft. Then, after pilot´s signal, the opposite end of the rope can be attached to the glider. d) As reaction to assistant signalization, the pilot of towing aircraft will tension the rope and signalize start of the aerotow. Amendment to Flight and Operations Manual of ATEC 321 Faeta UL aircraft - Aerotow ATEC v.o.s. Libice nad Cidlinou, Czech Republic Page 6 of 8 e) Lining up and take-off process is running at full engine power. After lift-up, it´s necessary to keep the engine continuous power until reaching the speed of 100 km/h and then to start climbing on stable speed of 100 - 120 km/h. During aerotow, the pilot of towing aircraft must do all manoeuvres fluently to enable glider to react in time and safely. When climbing, the pilot of towing aircraft must pay attention to towing speed, engine operating values and towed glider. f) When appropriate altitude and area are reached, the pilot of towing aircraft starts waving by wings to signalize that the glider is possible to disconnect. Descending is possible only when pilot of towing aircraft is sure, that the glider is completely disconnected. In case of descending with towing rope attached, do not make any sudden changes of flight direction and altitude. g) After descending over the aerodrome, the pilot of towing aircraft will release and drop down the rope along the runway in the altitude of 50m with respect to traffic at the aerodrome. Landing with rope attached is not recommended. h) After the pilot of towing aircraft is assured by watching the rear mirror or screen that the rope is disconnected, he can start increasing the engine power and climbing to circuit altitude so that he can make usual approach and landing according to Flight and Operations Manual of ATEC 321 Faeta. i) Attentively check and follow all flight and engine values and limits during aerotow! 1.8 Performances • Take-off distance with towed glider of 750 kg of MTOW: 500 m • Altitude reached after 600 m from start point: 15 m • Maximum climbing rate with towed glider of 750 kg of MTOW: 1,75 m/s • Optimum speed of towing (depending glider type): 100 – 120 km/h (55 – 65 kt) • Average fuel consumption during aerotow: 15 – 18 l/h • Maximum range of flight with max. fuel level of 70l during aerotow: 450 km Start and take-off distance of aerotow can be prolonged by 15% in case of rainy conditions or high grass on runway. Amendment to Flight and Operations Manual of ATEC 321 Faeta UL aircraft - Aerotow ATEC v.o.s. Libice nad Cidlinou, Czech Republic Page 7 of 8 Performances listed are considered when 750 kg of take-off weight and may vary depending on flight performances and characteristics of towed glider. 1.9 Operating limits • Maximum glider´s weight: 750 kg • Minimum towing speed: 90 km/h (45 kt) • Maximum towing speed: 150 km/h (80 kt) • Maximum strength of the rope release safety pin: 3000N When aerotow is performed, the towing aircraft can only be occupied with only one pilot on board. The pilot must be holder of valid pilot licence and authorized to aerotow. Aerotow towards air-wave area is prohibited. In case of unintended flight into air- wave area, the pilot of towing aircraft must leave this area immediately. Aerotow with more than one glider is prohibited. Aerotow from a terrain is prohibited. Take-off of the glider with one wing touching the ground (without assistant) is prohibited. 1.10 Description labels Towing aircraft must be equipped with description labels as follows: • The label „Attention to towing speed“ must be next to the speed indicator. • Towing rope release must be labelled as „Tow release“ • Back-up fuel pump switch must be labelled as „Fuel pump“ • Towed glider must be equipped with the label with clearly readable text, well visible to all crew: „LSA aerotow is performed at own risk of each person on board of the glider. LSA is not a subject to CAA authorization“. • Towing gear must be labelled as „Maximum towing rope strength is 3000N“ Amendment to Flight and Operations Manual of ATEC 321 Faeta UL aircraft - Aerotow ATEC v.o.s.
