    Flight manual DG-1000T 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 practised several times on the ground before flying the aircraft.

  • Page 33: Spin Recovery

    Flight manual DG-1000T 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 motorglider.

  • Page 34: Flight With Asymmetric Waterballast

    Flight manual DG-1000T 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 38: Landing With The Engine Extended And Stopped

    Flight manual DG-1000T 3.18 Landing with the engine extended and stopped Landing with the engine extended and stopped is not a potential risk. However due to the drag from the extended engine, the approach should be made not using airbrakes fully extended. Fully extended airbrakes may result in a heavy and uncomfortable landing.

  • Page 43: Filling The Fin Ballast Tank

    Flight manual DG-1000T 4.2.3 Filling the fin ballast tank This tank must be filled after filling the wingtanks. Determine the amount (see section 6.8.6). Connect the transparent funnel equipped filling hose (supplied with the aircraft) via the hose connector GRS 10-12 to the hose which comes out of the left rear end of the fuselage.

  • Page 44: Installation Of A Battery In The Fin

    Flight manual DG-1000T 4.2.5 Installation of a battery in the fin A battery in the fin may be installed optionally. To accomplish the installation the locking bow (part 10L35 made from piano wire) must be removed. The locking bow prevents the installation of a battery and serves as indicator if a battery is installed, as its ends are visible from the outside.

  • Page 45: Daily Inspection

    Flight manual DG-1000T 4.3 Daily Inspection Please bear in mind the importance of the inspection after rigging the glider and respectively each day prior to the first take off. It is for your safety. Caution: After a heavy landing or if other high loads have been imposed on your motorglider, you must execute a complete inspection referring to maintenance manual sect.

  • Page 50: Normal Procedures And Recommended Speeds

    Flight manual DG-1000T 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 51: Free Flight

    Flight manual DG-1000T 3. The DG-1000T pilot should keep his left hand at the throttle handle to enable him to close the throttle immediately in case the tow-plane terminates the tow (This is a standard procedure for powered aircraft pilots). 4.

  • Page 52: Cruise Engine On

    Warning: if there is a problem with the elastic damper element of the propeller adapter, the power plant may oscillate around its vertical axis with low frequency (1-10 Hz). If such oscillations start, switch off the ignition immediately. Report to DG Flugzeugbau prior to next engine use. 4.5.4 Powerplant extension-retraction in flight 4.5.4.1 Extension and starting the engine in flight...
  • Page 53 Flight manual DG-1000T 4.5.4.2 Stopping and retracting the engine in flight 1. Fly at 85-90 km/h (46-49 kts). 2. Bring the throttle back to idle. 3. Switch off the ignition. 4. The powerplant will be automatically retracted a certain distance to reduce the rotational forces on the propeller.
  • Page 54 Flight manual DG-1000T 4.5.4.3 Starting problems The engine is equipped with electric fuel injection (primer) instead of a choke valve. The automatic control of the primer enables engine starting with little risk of misoperation. To inspect the correct functions of the primer the DEI-NT displays a syringe symbol as long as fuel is injected (primer valve open).

  • Page 55: Approach And Landing

    Flight manual DG-1000T 4.5.5 Approach and landing Note: Always land in the gliding configuration, engine retracted, except in an emergency. 4.5.5.1 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.

  • Page 56: Engine Retraction On The Ground

    Flight manual DG-1000T 4.5.5.2 Landing with the engine extended and stopped See emergency procedures sect. 3.18. Land with the engine extended only if the engine can't be retracted. 4.5.5.3 Landing with the landing gear retracted Wheel-up landing is not recommended see emergency procedures section 3.10. After wheel-up landing check the fuselage belly and the tow hook for damage.
  • Page 57 Flight manual DG-1000T 4.5.7.2 Fin water ballast tank For optimal thermalling performance and handling water ballast in the fin tank should be used to compensate the forward movement of C.G. due to the mass of the wing water ballast. Please refer to section 6.8.6. Warning: It is prohibited to use the fin tank in icing conditions see sect.

  • Page 58: Flight At High Altitude And At Low Temperatures

    Flight manual DG-1000T 4.5.8 Flight at high altitude and at low temperatures With temperatures below 0°C (32°F) for instance when wave flying or flying in winter, it is possible that the control circuits could become stiffer. Special care should be taken to ensure that there is no moisture on any section of the control circuits to minimize the possibility of freeze up.

  • Page 59: Flight In Rain And Thunderstorms

    Flight manual DG-1000T 4.5.9 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 60: Aerobatics

    Flight manual DG-1000T 4.5.11 Aerobatics Caution: The DG-1000T is a high performance motorglider. 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 motorglider types.
  • Page 61 Flight manual DG-1000T 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- 1000T displays a large nose down pitch attitude after leaving the spin.
  • Page 62 Flight manual DG-1000T 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 63 Flight manual DG-1000T 4.5.11.2 Category A, Aerobatic Only approved with 17,2m span or 18m span without winglets, power plant retracted or removed and 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 2.13.
  • Page 64 Flight manual DG-1000T 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 65 Flight manual DG-1000T 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 66 Flight manual DG-1000T Flick manoeuvres The flick manoeuvres which have been tested with the DG-1000T should only be executed by experienced aerobatic pilots. The result is dependent as for any other motorglider on several parameters like inducing control speed, C.G. position, control movement during rotation etc.
