7.12.4 Choke
The choke control knob is located on the control panel to the right of the carburetor heat
and cabin heat controls.
The choke may only be used for a short time when starting the engine in cold
conditions. The throttle must remain in Idle. The choke knob is spring-loaded and
returns to the OFF position when released.
7.12.5 Carburetor Heat
The carburetor heat push-pull type control element is located on the control panel to the
left of the choke and cabin heat.
The correct use of carburetor heat prevents the formation of carburetor ice that can
cause the engine to run rough and, in the worst case, complete engine failure. If
carburetor icing is encountered, it is usually possible to slowly melt the ice by activating
the carburetor heat while maintaining the same power setting.
A carburetor temperature gauge with a caution zone marked is available from the
manufacturer as optional equipment.
The functionality of the carburetor heat should be tested before every flight.
NOTE
Carburetor heat reduces engine power and must be used in accordance with standard
rules and procedures.
