The S-20 RAVEN Taildragger is equipped with a steerable full-swivel tail wheel.
To taxi very small radius turns, push the desired rudder pedal and the brake
pedal in the same direction. This will disengage the steering cam and will allow
the tail wheel to swivel 360 degree. To re-engage use opposite rudder and brake
to stop turn and roll a few feet straight forward.
Prior to commencing the takeoff roll, align the aircraft in the intended direction of
takeoff and allow it to roll forward a few feet to straighten tail wheel and to assure
the steering cam is engaged before applying full power. This prevents possible
harmful side loading of the tail wheel.
FLAP SETTINGS
Normal takeoffs are accomplished with flaps UP or in the 1
st
or 2
nd
notch. Using
flaps reduces the ground roll and the total distance to clear an obstacle.
If flaps are used for takeoff, they should be left in that position until all obstacles
are cleared and a flap retraction speed of 60 MPH is reached.
SECURING THE AIRCRAFT
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-20 RAVEN 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 1320 lbs at each tie-down location. Secure the controls in the cockpit and
use the following tie down points:
•
Tail gear or Tail Tie Down Hook
•
Left forward wing strut (top - close to wing attach)
•
Right forward wing strut (top - close to wing attach)
If strong winds or gusts are advised, seek shelter for the aircraft.
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 up.
Monitor engine temperatures and adjust climb speed as required. A higher climb
speed will provide better engine cooling.
