DESCRIPTION AND OPERATION
7.11 ENGINE CONTROLS
PIPER AIRCRAFT CORPORATION
PA-28-181, CHEROKEE ARCHER
n
Engine controls consist of a throttle control and a mix ture 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 to
both the pilot and the copilot. 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 control lever in the full lean position. In
addition, the mixture control has a lock to prevent inadvertent activation of the mixture control. For
information on the leaning procedure, see the Avco-Lycoming Operator's Manual.
The friction adjustment lever on the right side of the control quadrant may be adjusted to increase or
decrease the friction holding the throttle and mix ture controls or to lock the controls in a selected position.
The carburetor heat control lever is located to the right of the control quadrant on the instrument
panel. The control is placarded with two positions: "ON" (down), "OFF" (up).
