Citabria 3-4
CAUTION
Limit the use of the starter to 30 seconds duration maximum
with a two minute cooling off period between each starter
engagement.
During cold weather operation, (below 20 F) it is recommended that the engine be preheated
by directing warm air through the opening in the bottom or front of the engine cowl. This practice
will prolong the service life of the engine and starter.
During the ground operation, the mixture should be FULL RICH and the carburettor air COLD to
insure good engine cooling and filtered air. Prolonged idle below 1000 RPM is not
recommended due to plug fouling and insufficient cooling air when the aircraft is not in motion.
TAXI
Taxi operations during high winds requires the conventional use of the flight controls. With a
head wind or quartering head wind, place the control stick full aft and into the wind. With a tail
wind or quartering tail wind, use the opposite procedures. The use of the wheel brakes in
conjunction with the rudder will assist the pilot in maintaining directional control.

High power operation (above 2200 RPM) and engine run-up should be made into the wind and
kept to a minimum especially during high temperature conditions. The stick should also be held
fill aft to prevent the possibility of the aircraft nosing over.
