    Flight manual DG-1000S 3.1 Introduction Section 3 provides a checklist and amplification for coping with emergencies that may occur. Emergency situations can be minimized by proper pre-flight inspections and maintenance. Caution: Canopy jettison and bailing out should be trained several times on the ground before flying the aircraft.

  • Page 29: Spin Recovery

    Flight manual DG-1000S 3.5 Spin Recovery Apply full opposite rudder against direction of the spin, pause. Then ease stick forward until the rotation ceases, centralize the controls and carefully pull out of the dive. The ailerons should be kept neutral during recovery. Caution: To prevent unintentional spinning do not stall the sailplane.

  • Page 30: Flight With Asymmetric Waterballast

    Flight manual DG-1000S 3.8 Flight with asymmetric waterballast If you suspect that the waterballast does not dump symmetrically you have to close the dump valves of the wingtanks immediately, to avoid greater asymmetry. Asymmetry can be verified by the necessary aileron deflection in straight flight at low airspeeds.

  • Page 31: Emergency Ground Loop

    Flight manual DG-1000S 3.11 Emergency ground loop If there is the risk of overshooting the landing strip you have to decide at least 40 m (130 ft) before the end of the field to execute a controlled ground loop: - If possible turn into the wind! - At the same time try to lift the tail by pushing the stick forward.

  • Page 42: Normal Procedures And Recommended Speeds

    Flight manual DG-1000S 4.5 Normal procedures and recommended speeds 4.5.1 Launch Due to the towhook position being in the middle of the fuselage and the excellent effectiveness of the ailerons and rudder, the possibility of wing dropping or ground loops, even on a slowly accelerating aerotow is reduced. Take-off with strong crosswind is possible.

  • Page 43: Free Flight

    Flight manual DG-1000S 4.5.1.2 Winch launch Winch launch is only allowed at the C.G. tow hook! Set the trim to neutral for winch launch. Caution: During ground roll and initial take-off (especially when flying solo) push the control stick to a forward position to prevent excessive nose-up pitching rotation during initial take-off.

  • Page 44: Approach And Landing

    Flight manual DG-1000S 4.5.3 Approach and landing 4.5.3.1 Normal landing It is recommended to dump the waterballast before landing even on airfields. Dump the ballast before an outlanding in any case. Abeam the landing point extend the landing gear. In calm weather approach with approx.

  • Page 46: Flight With Water Ballast

    Flight manual DG-1000S 4.5.4 Flight with water ballast 4.5.4.1 Wing tanks Recommended ballast for smooth thermals: rate of climb ballast litres U.S. gallons below None 1,5 – 3 300-600 more than max. ballast Do not exceed the maximum gross weight when loading the water ballast. The maximum quantity of water allowed is dependent on the empty weight and the cockpit load (see section 6.8.5).

  • Page 47: Flight At High Altitude And At Low Temperatures

    Flight manual DG-1000S 4.5.4.4 Dumping of the waterballast First open the fin tank, then open both wing ballast tanks together. Do not empty one wing tank after the other to avoid an asymmetric loading condition. Warning: If the fin ballast dump valve handle can be operated with unusually low effort (force of the retaining spring is no more apparent) you must suspect that the fin ballast can’t be dumped any more.

  • Page 48: Flight In Rain And Thunderstorms

    Flight manual DG-1000S 4.5.6 Flight in rain and thunderstorms With light rain the stall speed and the sink rate increases slightly and the approach speed has to be increased. Warning: Flights and especially winch launches in the vicinity of thunder storms should be avoided.

  • Page 49: Aerobatics

    Flight manual DG-1000S 4.5.8 Aerobatics Caution: The DG-1000S is a high performance sailplane. Therefore the speed increase in the dive, especially in inverted flight is high. Training aerobatics therefore should only be executed after a rating with an experienced pilot, or if you can master the manoeuvres on other sailplane types. In any case don't try to execute the manoeuvres with entry speeds other than those listed.
  • Page 50 Flight manual DG-1000S Spins Caution: Prolonged spinning is satisfactorily accomplished with aft C.G. positions. If prolonged spinning is intended, ballast in the ballast box in the fin should be used to achieve an aft C.G. position, see section 6.8.7. It is not necessary to extend the dive brakes during spin recovery. The DG-1000S displays a large nose down pitch attitude after leaving the spin.
  • Page 51 Flight manual DG-1000S Stall turn To fly a stall turn safely, proceed as follows: Don’t choose an entry speed of less than 200 km/h (108 kts.). During the pull out, when reaching the vertical flight path initiate rotation at min. 150 km/h (81 kts.) with the rudder. Push the rudder quickly, but not abruptly.
  • Page 52 Flight manual DG-1000S 4.5.8.2 Category A, Aerobatic Only approved with 17,2m span or 18m span without winglets, without water ballast, max. mass 630 kg (1389 lbs.) and with the weight of the rear pilot compensated by ballast in the ballast box in the fin see section 6.8.7 and with the required equipment installed see section 2.10.
  • Page 53 Flight manual DG-1000S Inverted flight The speed in inverted flight should preferably be chosen between 120-200 km/h (65-108 kts.). At speeds greater than 185 km/h (100 kts.) no full control deflections are allowed. Warning: When the speed is reduced below the minimum speed (depending on weight and C.G.
  • Page 54 Flight manual DG-1000S Slow roll After reaching the entry speed of 180 - 200 km/h (97-108 kts.) the nose must be raised slightly above the horizon. After returning the stick to neutral, full aileron has to be applied in the desired direction. When the wing passes the vertical position the rudder must be applied a little in upwards direction.
  • Page 55 Flight manual DG-1000S Flick manoeuvres The flick manoeuvres which have been tested with the DG-1000S should only be executed by experienced aerobatic pilots. The result is dependent as for any other sailplane on several parameters like inducing control speed, C.G. position, control movement during rotation etc.
