(5) Auxiliary Fuel Pump Switch -- "HI."
(6) Ignition Switch -- "START" (until engine starts windmilling).
(7) Mixture -- Adjust for a fuel flow between 10 to 35 lbs/hr while
starting. Then adjust for maximum engine acceleration to 1000 RPM.
(8) Auxiliary
Fuel Pump Switch -- Off.
(9) Throttle -- Adjust for smooth engine acceleration and to prevent
propeller overspeed.
(10) Power -- Increase slowly until cylinder head temperature
reaches 200°F.
SINGLE-ENGINE APPROACH.
(1) Landing Gear -- Extend on downwind leg.
NOTE
If the front propeller is feathered, the landing gear must
be extended with the emergency hydraulic hand pump (un-
less an optional rear-engine hydraulic pump is installed).
Allow 2 to 3 minutes for emergency gear extension operation.
(2) Wing Flaps -- Minimum setting necessary (until landing is
assured).
(3) Airspeed -- 90 to 100 MPH in approach.
SINGLE-ENGINE GO-AROUND.
(1) Power -- Full throttle and 2800 RPM.
(2)
Airspeed -- 100 MPH (95 MPH with obstacles ahead).
(3) Wing Flaps -- Retract to "1/3" down.
(4) Cowl Flaps -- Open on operating engine.
(5) Wing
Flaps -- Retract after obstacles are cleared and a safe
altitude and airspeed are reached.
(6) Landing Gear -- Retract after obstacles are cleared.
NOTE
With the
front engine inoperative, leave the landing gear
extended (unless an optional rear-engine hydrauliC pump
is installed).

SIMULATED ENGINE-OUT OPERATION.
Engine-out procedures should be practiced in antiCipation of an emer-
..ney. This practice should be conducted at a safe altitude with full pow-
.r operation on both engines. Practice should be continued until (1) an
lnltinctive corrective reaction is developed, and the corrective procedure
II automatic, and (2) airspeed, altitude, and heading can be maintained
tUily while the airplane is being prepared for climb. In order to simu-
late an engine failure, set both engines at full power operation, then at a
Ohosen
speed, pull the mixture control of one engine into "ICO" (idle cut-
otf) and proceed with single-engine emergency procedures.
Simulated single-engine procedures can also be practiced by setting
the propeller RPM of an idling engine at zero thrust as shown in figure
1.2, In this case, the mixture would be left at the pOSition required for
full power as appropriate for the particular altitude.
