SINGLE ENGINE PROCEDURE

Whenever hangar fliers "work over" the P-38, sooner or later single engine flight procedure is brought up; and we '38 test pilots are no exception. The other day when the chief heard us "flying" around the waiting room on single engine, he broke up our little session by saying: "There's a right and wrong way of doing everything - particularly flying on one engine. Our engineers have spent many hours checking the best procedures for single engine operation, and it's about time you new fellows are acquainted with these findings. It isn't hard to fly on one engine - it's just knowing how."

The dead engine's mixture control should be set to idle cut-off, to reduce fire hazard by stopping the flow of fuel. Set the feathering switch to full feather, and pull the throttle back to "close". That's all there is to getting set for single engine flight.

If the flight is going to be for any duration though, you'll find that the following operations make for safer and better flying: turn off the booster pump of the dead engine, trim the rudder tab, close the tank selector valve, the prestone shutter, and the oil cooler flap of the dead engine.

Don't burn up your good engine-31 inches of mercury with 2300 R.P.M. is satisfactory cruising power, and for single engine climb 37 inches with 2600 R.P.M. is recommended. The use of more power is unnecessary. The single engine power stall occurs at 90 M.P.H. indicated, and you will experience a big change in directional trim with change in speed, comparable to the torque effect in single engine airplanes.

Joe Towle* Says:

Don't be afraid to lose one engine - remember you still have a mighty fine single engine ship under you".

Single engine landings are a cinch - but never count on a twin engine plane maintaining altitude with both the gear and flaps full down. Once full flaps are extended the landing MUST be made, so extend flaps 100% only when you see it's "in the bag".

 

 

 

REMEMBER:

   For Single Engine Flight due to "Flakitis"*

  • Reduce power on live engine and correct yaw with hard opposite rudder

  • Increase power slowly

  • Set dead engine mixture control to idle cut-off

  • Feather up

  • Close throttle on dead engine.

* Flakitis - A serious and sometime fatal disease commonly found in engines returning  from enemy lines. Loss of manifold and oil pressures, followed by spasmodic coughing,wheezing, are general symptoms.
