  • Page 53 The S-21 OUTBOUND is a light aircraft! TAXING (Ground Handling) The S-21 OUTBOUND is a light aircraft. Concentrate on taxiing until the moment the aircraft is tied down. When taxing, it is important that speed and use of brakes is held to a minimum, and that all controls are utilized to maintain directional control and balance.
  • Page 54 When taxing in strong crosswinds a little extra throttle will help the aircraft turn due to the increased airflow over the rudder. Use caution not to use excessive throttle, sudden throttle movements, or excessive braking.

  • Page 55: Flap Settings

    If the aircraft must be left unattended outdoors, always secure it with tie-downs. NEVER use the brake as a parking brake with the intention of leaving the aircraft unattended. The S-21 OUTBOUND is a light aircraft! The type of tie-downs used is a matter of personal choice. A good "rule-of-thumb" is to ensure that what you secure the aircraft to (and with) will restrain at least 1800 lbs at each tie-down location.

  • Page 56: Hot Weather Operation

    RANS S-21 OUTBOUND TEXT MANUAL 14-55 HOT WEATHER OPERATION Avoid prolonged engine operation on the ground. Turn the airplane into the wind to assure better airflow through the cowling during run Monitor engine temperatures and adjust climb speed as required. A higher climb speed will provide better engine cooling.
