                                  HANDLING


    31.   Management of the fuel system

          The tanks may be used in any convenient order, but when
          a series of short flights is being made, it is advisable to use
          the tanks so that the contents of each tank remain ap-
          proximately equal.
          If it is necessary to run a tank dry, this should be done at
          a safe height and, when the engine cuts, the throttle
          should be closed before the other tank is selected, to
          avoid overspeeding of the propeller.

    32.   Starting the engine and warming up

    (i)   Carry out the pre-flight checks, and then if the engine
          is to be started from external sources turn the ground/
          flight switch to GROUND and have a 24-volt starter bat-
          tery plugged in.

   (ii)   Set the controls as follows:

          Ignition	...	...	OFF
          Fuel cock	...	...	To desired tank
          Throttle	...	...	½" open
          R.p.m. control lever	...	Fully forward
          Air-intake heat control...	Cold air (selector in)
          Air-intake filter control...	Filtered air (selector out)

  (iii)   Have the propeller turned over two complete revolutions
          by hand.

   (iv)   Operate the priming pump until the pipelines are full.
          This may be judged by a sudden increase in resistance.
          Then prime the induction system with the following
          number of strokes according to the air temperature:-
          
    Air temperature °C.    +30 +20 +10  0 -10 -20 -30 -40
    Normal fuel              3   4   4  5
    High volatility fuel                1   2   3   4   4
             
          NOTE.-The number of strokes given above apply when
                the engine is cold.   Less priming will be required
                when it is warm and when it is hot it is unlikely
                that any priming will be requred.
