Crosswinds prolong landing runway length due to elevated airspeed that should be used, see previous page. Performing a crosswind landing, the wing-low method should be used. When using the wing-low method it is necessary to gradually increase the deflection of the rudder and aileron to maintain the proper amount of drift correction.

  • Page 48 ALPHA Trainer www.pipistrel-aircraft.com Performance REV. 0 Effect of the wind Wind (head, cross or tailwind) affects aircraft’s ground speed (GS). Headwind on takeoff or landing causes the takeoff and landing distance length to shorten as the GS is smaller during these two flight stages. The opposite holds true for tailwind on takeoff and landing as tailwind prolongs takeoff and landing distances significantly.

  • Page 49: Climb Performance

    Cruise airspeed 108 kts (200 km/h) Best economy cruising level or the ALPHA Trainer is 6000 ft. There, cruise performance is equivalent or better than above due to IAS-TAS relation, but fuel consumption is lower. At these parameters the fuel burn is around 3.6 USgal (13.6 L) per hour.
