Descriptions and Operations

1. Elevator Trim Wheel: Clicking on top of the wheel will lower the nose, clicking the bottom raises the nose. The Trim Indicator (item 19 on the Main Panel) is on the main panel.

2-5. Throttles 1 thru 4: There is a master click spot to move all the throttles simultaneously between numbers 2 and 3.

6. Fuel Tank Selector Lever: With the lever forward (default) fuel will be drawn from the main tanks. Engines 1 & 2 from the left mains engines 3 & 4 from the right mains. With the lever in the middle fuel will be drawn for the Auxiliary tanks. Engines 1 & 2 from the left aux engines 3 & 4 from the right aux. With the lever full back the tanks are closed. There are three click spots on the lower part of the lever. The "UP" or "+" spot puts the lever in the forward or main tank position. The plain "HAND" selects the center or Aux tank position. The "DOWN" or "-" selects tanks off.

7. Master Prop Sequencer Lever: Using this lever will adjust all the props simultaneously and bring them into sequence.

8. Prop Reversed Indicator Lights: These lights will be on when the props are in the reversed position.

9. Prop Governor Limit Lights: These lights will be lit when the props are at there limits in the full coarse (low rpm) and fine (high rpm) positions.

10. Electric Prop Adjustment Switches: These switches are used to make fine incremental adjustments to the props.

11. Martin Bar – Automatic Prop Reversal: This bar should be engaged after landing. Drop the throttle to idle, throw the Martin Bar, and increase the throttle to around 30" MAP. After slowing to 40-50 kts, drop the throttle to idle and the bar will release (or you can click it to release it at any time).

You can use up to full throttle during prop reverse in an emergency.

12. Martin Bar Engaged Indicator Light: This light will flash when the Martin Bar is engaged.

13. Left Wing Fuel Crossfeed Lever: In the forward (default) position there is no crossfeed between any tanks. With the lever in the middle position crossfeed will occur between the left tanks (not active at this time). With the lever in the back position you will get crossfeed across all tanks.

14. Right Wing Fuel Crossfeed Lever: In the forward (default) position there is no crossfeed between any tanks. With the lever in the middle position crossfeed will occur between the right tanks (not active at this time). With the lever in the back position you will get crossfeed across all tanks.

15. Mixture Levers: Engines 1 thru 4 mixture levers. Up is rich down is lean.

16. Landing Gear Handle: Handle up gear will retract, once retracted position the handle in the middle locked position. Handle down, gear will extend if airspeed is below 175 knots indicated.

17. Carburetor Heat Levers: Engines 1 thru 4 carb heat. Down (default) is cold, up is hot.

18. Flap Handle: Up the flaps are retracted, down they are extended. Do not exceed the flap extension speed of 175 KIAS.

19. Speed Brake Lever: When clicked, the main gear will be extended as a speed brake. This will slow you down, typically on descent while approaching an airport for landing. Note that you will NOT be able to raise them back up again until you are going slower than about 170 kts, since the hydraulic system is not strong enough to raise them against the wind blast any faster. The gear lights will indicate the main gear down, plus the red transit light to remind you the speed brake is down.
