21. ICE LIGHT SWITCH (if Equipped)
Lighting to alert the pilot of ice formation on surfaces of an aircraft.
22. READING LIGHTS SWITCH
Momentary switch operates 4 overhead lamps in 3 modes. Reading Light Switch UP posi-
tion, only the Pilot reading light is activated. With Reading Light Switch in Down position, ALL
reading lights are activated. Passenger switches are located in the overhead panel.
23. DOME LIGHTS SWITCH

switch operates 1 main dome light in the center of overhead console.
24. “HIGH BOOST” FUEL BOOST PUMP SWITCH
The High Fuel boost pump switch operates the fuel boost pump on high power. The high
boost setting is capable of operating engine at reduced power in case of engine driven fuel
pump failure or severe fuel filter blockage. Selecting High Boost while Low Boost is powered
on causes Low Boost to turn off. Continuous operation should be avoided except in an emer-
gency. Never run the boost pump without fuel in the system.
Pushing HIGH BOOST pump switch ON when engine driven pump is operating
properly will cause engine to quit due to excessive rich fuel mixture.
-CAUTION-
25. BOOST PUMP SWITCH (LOW BOOST)
The Low Fuel boost pump switch operates the fuel boost pump on low power to provide a
means of suppressing fuel vapor from fuel system during hot day and high altitude condi-
tions. Low boost may also be used as an engine starting aid. Continuous operation of the low
boost is permitted. Never run the boost pump without fuel in the system.
Pushing LOW BOOST pump switch ON when engine is operating properly at idle
conditions will cause engine to run rough or quit due to excessive rich fuel mix-
ture. For this reason LOW BOOST should be turned off except where prescribed in
the normal operating procedures.
-CAUTION-
26. AUTOPILOT POWER SWITCH
A manually operated rocker switch located on the instrument panel. This switch will provide
power to the autopilot system and the Manual Electric Trim (MET). There is another discon-
nect using the MET and AP disconnect on the Pilot LH side control yoke. If the AP master
switch is OFF, there will be an alert “FAILED PATH - A data path has failed”.
27. WING FLAP SWITCH
Flap switch, on lower instrument panel, operates the electrically-actuated wing flaps. The
flap switch incorporates a pre-select feature for TAKEOFF and FULL DOWN positions. Move
switch down to first détente position to obtain TAKE OFF flaps (10
). Move switch to full down
position to select FULL DOWN flaps (33
). When flap switch is moved UP to either TAKEOFF
position or FULL UP position the flaps will retract to the selected position.
Positioning Flap Switch to the UP position retracts the flaps completely.
