Engine Speed for 2 min – Set 2000 RPM
Warming up oil – Set 2500 RPM until oil temperature reached 50°C Flight Procedures TOMARK Viper SD-4 RTC Page: 13 Rev 2, 19 Nov 2018 CAUTION The oil pressure must rise within 10 seconds after starting. Only when the oil reaches a stable pressure, the engine’s RPM may be increased. If the oil is cold constantly monitor oil pressure since because of an increased flow resistance in the suction branch the oil pressure may drop again. To avoid acceleration stresses when starting the engine set THROTTLE LEVER to idle. For the same reason, after reducing the throttle wait for about 3 seconds before increasing the THROTTLE LEVER to achieve constant RPM of the engine. If the airplane is standing on a stony surface do not start the engine – there is a risk of preopeller by sucked in stones. NOTE When starting a cold engine, move THROTTLE LEVER to idle and pull-out and held the choke control. When starting a warm engine, set the THROTTLE LEVER slightly over the idle position. If the engine does not start, repeat the starting not earlier than in 2 minutes, during which the starter will cool off. 4.4. Before taxi

VX (Best angle of climb speed) 53 KIAS VY (Best rate of climb speed, at Sea level) 66 KIAS VY (Best rate of climb speed, 10 000 ft) 60 KIAS 4.12. Turning to crosswind leg When reaching 500 ft AAL (600 ft AAL in case of LH circuit of RWY31 LHGD) turn to the crosswind leg. Before starting the turn look into direction of crosswind leg to check the airspace and the direction of crosswind leg. The speed in the turn shall be 70 KIAS so lower the nose to reach and maintain 70 KIAS during Page: 20 Flight Procedures TOMARK Viper SD-4 RTC Rev 2, 19 Nov 2018 the turn. Fly the attitude accordingly until the nose points to the new direction. When the turn is completed raise the nose again for the 65 KIAS pitch attitude. Consider wind condition, this turn is normally less than 90 degrees because of the wind correction. Recommended bank angle during climb is less than normal bank angle. 4.13. Turning to downwind leg This turn shall be initiated when the landing threshold can be seen looking 30 degrees behind the airplane’s lateral axis. Before starting the turn check airspace in the direction of the downwind leg. 4.14. Transition to level flight Shortly before reaching 1000 ft AAL lower the nose to maintain the circuit altitude (1700 ft at LHGD). Let the aircraft to accelerate through 75 KIAS at climb power and then set 4400 RPM, trim aircraft for level flight.
Engine parameters – In green bands
FUEL selector – Position to the tank with the higher quantity of fuel or LEFT if necessary Flight Procedures TOMARK Viper SD-4 RTC Page: 21 Rev 2, 19 Nov 2018 NOTE The fuel system features a return fuel line that ends in the left hand side fuel tank. When flying on the right hand side tank some fuel (approx 5-10 l/h) is pumped into the left tank. Therefore to maintain fuel symmetry during the flight the time increment on the left fuel tank is more than on the right hand side fuel tank. NOTE The fuel quantity indication system is most accurate in horizontal stable flight. During maneuvering the fuel level may be indicated with some time delay. 4.15. Downwind leg Fly the aircraft parallel to the RWY centerline, consider spot wind and make directional correction. At the beginning of downwind check fuel and engine parameters. Change fuel tank as necessary. When passing abeam of threshold and before the base turn:
CARB HEAT – Pull
FUEL Pump – Switch ON Announce intention on radio:  RT: “Gödöllő Traffic, HA-BEW before turning left / right base for RWY 31 / 13 touch and go / full stop landing.” 4.16. Turning to base leg Page: 22 Flight Procedures TOMARK Viper SD-4 RTC Rev 2, 19 Nov 2018 The position for the base turn is when the landing threshold can be seen 35 degrees behind the lateral axis. This turn is a level turn and normally more than 90 degrees due to wind correction on the base leg. After the turn reduce engine power and maintain level flight until speed is less than 80 KIAS
THROTTLE LEVER – 3000 RPM
FLAPS – Position I Lower the nose for the descent attitude and maintain 70 KIAS. Do not let the speed go above 80 KIAS with the flaps extended to any position (VFE=79 KIAS) 4.17. Final turn The position for the final turn is when the landing threshold is 10 degrees in front of the lateral axis (consider wind). The speed for this turn shall be 70 KIAS so before the turn lower the nose and turn into the extended RWY centerline. Adjust the bank angle in turn if necessary to achieve the optimal position. Do not exceed bank angle of 30 degrees! Keep approach speed and approach angle with pitch and thrust together! 4.18. Positioning the aircraft for landing The landing flap shall be extended for landing earlier or later as the wind strength requires it. The aircraft shall be configured for landing not below 300 ft Flight Procedures TOMARK Viper SD-4 RTC Page: 23 Rev 2, 19 Nov 2018 AAL. If the intention is TOUCH and GO :
CARB HEAT- OFF(PUSH) on short FINAL In case of Landing with:
FLAPS – Position I
MAINTAIN SPEED – 70 KIAS
FLAPS – Position II
MAINTAIN SPEED – 65 KIAS
FLAPS – Position III
MAINTAIN SPEED – 60 KIAS Consider wind gust to define the actual Approach speed! NOTE FLAP POSITION III is only to be used for emergency and precautionary short field landings as described in AFM Section 3. At this flap setting, full trimmability is not possible. FLAP POSITION III is allowed to use ONLY for precautionary short field landing training with instructor! 4.19. Landing Before landing Adjust the engine power and the pitch in order to point the nose to the aiming point approximately 30 meters in front of the threshold mark that is approximately 50 metres in front of the touch down zone. With increasing Page: 24 Flight Procedures TOMARK Viper SD-4 RTC Rev 2, 19 Nov 2018 engine power, raise the nose and when reducing engine power, lower the nose in order to maintain the appropriate approach speed. Reaching 3-5 meters height,reduce the engine power.
THROTTLE LEVER – Set IDLE and brake the angle of the approach. Look left 25 degrees 30 meters forwards. Start the flare at the main wheels 30-50 cm distance from the ground. In case of crosswind bank into the wind and keep the direction with applying opposite rudder so that the plane will not move sideways from the landing axis. Land on the main wheels first (on the lower one first in crosswind), let the nose wheel gently touch the ground and keep it eased by holding the stick slightly pulled while rolling out. Control the roll out with the rudder and neutral the aileron as the speed drops. VS (Stalling speed in clean configuration) 49 KIAS VS1 (Stalling speed in config Flaps POSITION II) 43 KIAS 4.20. Go around In case the landing cannot be completed safely (due to other traffic, vehicle or person on the RWY / the aircraft is too high or low for the safe landing / the weather is not suitable for the landing / due to wind / RWY is not visible) GO AROUND MUST BE PERFORMED. Flight Procedures TOMARK Viper SD-4 RTC Page: 25 Rev 2, 19 Nov 2018 Apply full power, maintain RWY track, verify the CARB HEAT is OFF.

REMARKS During cross country flight monitor and manually compensate asymmetrical fuel consumption by switching fuel selector valve. The maximum allowed difference of fuel amount between the tanks is 15 litres. Switch ON the electric fuel pump prior to swap the fuel feeding from one thank to another. Monitor the fuel pressure after switching fuel supply and turn the electric fuel pump off if the fuel pressure does not change. Approaching Gödöllő either from airspace work or cross country flight, check fuel 1 minute prior joining traffic pattern and change fuel tank if necessary.
