Fairly straightforward and familiar to anyone who is familiar with Constant Speed Propeller aircraft. Throttle friction knob is just visible to the right hand side and below the mixture levers (Reds).

Mixture Levers The drill for using these at startup is explained in the checklist. Note that the left engine may require a full 10 seconds priming prior to starting. There are basically four settings to remember. (16,12,10 and Full Rich)

Normal Climb 16 Galls per hour

Economy Cruise 12 Galls per hour

Hold 10 Galls per hour

Cruise and Hold S/E 12 Galls per hour

Fuel Flow can be monitored via the Fuel Flow Meter

Propeller speed control is via the blue levers, the further forward the levers, the finer the blades. As a general rule it helps to remember that there are basically three setting for props:

2200 rpm Economy Cruise, Airways Descent, Level and Descent in Hold.

2400 rpm Normal Climb, Level and Intermediate Descent both with 25 Degrees Flap, Cruise and Hold (S/E)

2575 rpm Full Fwd (ie fine) For All other phases of flight.

Check the Speeds on the RPM gauge.

Engine Power controlled via the Black levers and Manifold Pressures are displayed on the MAP Gauge.

Note the Idle setting. When pulled to the rear of this setting, ie into the closed position, and the gear is not down, a Warning Horn will sound, and the light will flash in the Gear Handle. The aircraft will display a beat frequency if the engines are not synchronized, and before attempting to alter the prop settings, check that the MAP readings are the same.

Power settings (together with prop settings and fuel flow) for all phases of flight are shown in the Checklist (at the back page). These may vary according to loading, atmospheric conditions, and so on, and the figures given should be used as a guide only.
