Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo Introduction This Manual is intended for everyone who flies and maintains the DAR-Solo series airplane with one of the offered engines: Hirth F-33 BS (28 HP) - single cylinder, two-stroke engine, aircooled or Polini Thor 250 DS (36HP) - single cylinder, two-stroke engine, water cooled The Manual contains graphics aerodynamic characteristics of the DAR – Solo airplane with described standard engines.

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo LIMITATIONS AND SAFETY INFORMATION Limitations DAR Solo is an aircraft that falls in the LTF-UL Category. It is designed to be used for any maneuvers as:  Normal flying maneuvers;  Stalls (except whip stalls); and  Lazy eights, chandelles, and steep turns, in which the angle of bank is not more than 60 degrees. The following limitations are imposed on the speeds and loading of the airplane: VS1 = 55 km/h VSF = 51 km/h VNE = 150 km/h VA=109 km/h VF = 92 km/h VFE=83 km/h Max Wind Limits = 5 m/s Engine Limitation = no negative loads more 3...

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo Empty CG = 44,5% MTOW CG = 33%  DO NOT FLY WITHOUT INSTALLED WING CENTRAL SECTION FAIRING!  Do not overload the Airplane. The Max Gross Weight should not exceed 260 kg. Safety For your safety read this manual thoroughly and make sure you understand the capabilities and limitations of the airplane. If you have any additional questions contact the manufacturer before operating the machine.  Never fly when you don’t feel prepared for the conditions of the flight!  Never fly under influence of alcohol or drugs!  Never fly if you have not...

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo IGNITION Before ignition you have to do the following: - put the wheel chocks under the wheels; - check the availability of a fire extinguisher; - in start-up with an electrical starter (autonomous) the procedure must be done at the command “Clear Propeller”. You must not push the START ignition button if you do not receive the “Clear” answer from the start-up supervisor! - put the levers at min (at a temperature less than 10°C – at the support of the installed stop). Open (pull out) the mixture control (suction ducts). - push the START...

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo ENGINE WARM UP When you reach CHT=180°C of CHT increase revolutions to n=5000 rev/min. The increase of revolutions has to be done smoothly, without interruption. After running at these rpm-s for 10 seconds, the lever have to be drawn backwards smoothly till a support end (lever to min) is reached, the rpm fall has to be monitored until they reach the minimal n operation must be done smoothly but in a slower than that of the lever motion. That is the normal way to do it having in mind the fixed pitch propeller and the two-stroke engine....

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo nmax=7500(+/-100) rev/min. CHT must stay below 280°C. In 5 seconds draw in the lever to their minimum. In case of unusual engine run (vibrations, interruptions, etc.), draw the lever in to their minimum and turn off ignition using the main switch. TAXIING You have to start taxiing with pedals in neutral position. Then increase engine revolutions smoothly to 5000 rev/min and ease off the brakes. Taxing must be done at a speed of 5-7 кm/h and engine revolutions of 5500-6000 rev/min. The taxiing speed has to be controlled by changing the...

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo FLIGHT Take Off Start taxiing to the runway and stop on the center line. Apply the brake. Set the flaps to 11°. Look around the cockpit from left to right. Check the instruments. Smoothly push the throttle to maximum position. Wait untill the engine reaches maximum RPM, be sure it works well and ease off the brakes. In the first part of the take off run keep the heading by using the pedals. CAUTION! Do not use brake during take off! When the speed increases above 20-25 km/h, the airplane starts to “obey” the rudder, too. Motion with pedals...

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo Upon reaching the speed of V=60-65 km/h smoothly proceed to climbing at a speed of Vy=2-2.5 m/s. At a H=50m decrease vertical speed to 0.5-1.0m/s and retract the flaps. HORIZONTAL FLIGHT Reduce the RPM-s down to 6800 and continue climbing at a speed of V=80-85 km/h and Vy=1.0m/s. Turns along the pattern are done with banks of up to 30°, decreasing the vertical speed to Vy=0.5-1.0 m/s and applying power to increase the RPM by 500 before each turn. In flight the RPM-s keeps 6800. A speed of horizontal flight. The maximal airspeed under...

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo LANDING APPROACH Upon flying over the traverse in the beginning of the runway mark the time. After 20-25 s decrease the airspeed to V=70 km/h, at a height of H=150 m start the third turn with a maximum bank of 30° and a plan to complete the turn at a height of H=120 m. After leaving the turn set an airspeed of V=65(70) km/h and vertical speed of Vy=1.0-1.5 m/s; lower the flaps to 11°. After 12-15 s (visual, watching closely runway approach) start the fourth turn at a height of Н=80m, a speed of V=65(70) km/h and a bank of up to 30° with a...

Aeroplanes DAR ltd. Brief Flight Manual DAR – Solo NOTE: Landing must be on two points, with a smooth pulling back of the stick along the descend rate of the airplane. The airplane touches down at a speed of V=55 km/h. At the moment of touch down keep the stick in the same position as before, then pull the stick back. Upon decrease speed smoothly drop the nose wheel. The pedals must be centered, before touch down of nose wheel. Apply the brakes with the rate of decreasing speed. NOTE: 1. Speed is given for Ggross=260kg in brackets respectively. 2. We do not recommend bank over 30° with a...
