degrees extended, and fully (34 degrees) extended. To extend the flaps, pull
the flap handle aft to the desired flap setting, hesitating momentarily as the
ratchet locks into position. To retract the flaps, press the button on the end
of the flap handle to disengage the ratchet and push the flap handle to the
desired flap setting. When the flap setting is changed, there is an associated
pitch change in the airplane. This pitch change can be corrected either by
elevator trim or increased control wheel force.
7.11 ENGINE CONTROLS
Engine controls consist of a throttle control and a mixture control lever.
These controls are located on the control quadrant on the lower center of the
instrument panel (Figure 7-5) where they are accessible from both seats. The
controls utilize teflon-lined control cables to reduce friction and binding.
The throttle lever is used to adjust engine RPM. The mixture control
lever is used to adjust the air to fuel ratio. The engine is shut down by the
placing of the mixture lever in the full lean position. For information on the
leaning procedure, see the Avco-Lycoming Operator’s Manual.
The friction adjustment wheel in the center of the control quadrant may
be adjusted to increase or decrease the friction holding the throttle and
mixture controls or to lock the controls in a selected position.
The carburetor heat control lever is located on the left of the control
quadrant on the instrument panel. The control is placarded with two
positions: “ON” (down), “OFF” (up).
7.13 FUEL SYSTEM
Fuel is stored in two sixteen gallon (15 gallons usable) fuel tanks, giving
the airplane a total capacity of thirty-two U.S. gallons (30 gallons usable).
The tanks are secured to the leading edge of each wing with rivets. When
installed, a filler neck indicator aids in determining fuel remaining when the
tanks are not full.
The fuel tank selector control (Figure 7-5) is located in the center of the
engine control quadrant. The button on the selector cover must be depressed
and held while the handle is moved to the OFF position. The button releases
automatically when the handle is moved back to the ON position. A fuel
quantity gauge for each fuel tank is located on either side of the fuel tank
selector, each gauge on the same side as the corresponding fuel tank.
