Engine controls (from pictures of the engine control box and other sources)
- Throttle levers
- Sets auto boost datum.
- fcs/throttle-cmd-norm[0|1|2|3]
- Mixture levers
- Sets auto mixture datum: WEAK - NORMAL - RICH - ...
Might have the positions NORMAL - RICH - +1 PSI - +3 PSI
The latter two settings are some sort of boost override positions.
Here full rich mixture bumps the maximum boost from 2.5 to 4.25 PSI.
- fcs/mixture-cmd-norm[0|1|2|3]
- Airscrew pitch control levers
- Has the positions COARSE and FINE. No feathering was available.
- fcs/advance-cmd-norm[0|1|2|3]
- Engine cut-out levers
- Two levers cutting the fuel to the inner and outer engines, respectively.
Has the positions ON and OFF.

<documentation>
According to [Cassidy:2004:FE] the Pegasus engines had automatic
boost and mixture controls. I think take-off boost (boost override) was only
available with the mixture levers moved through a gate past the
RICH position.
[Cassidy:2004:FE] pp 152:
"The mixture control check was normally done by the First
Officer. For each engine in turn, he moved the mixture control
lever back from NORMAL to RICH -. + 1 lb. sq. in, then through the
gate to +3 lb. sq. in. and back to NORMAL."
[Cassidy:2004:FE]: Fuel consumption for "normal" operation varied
between 107.5 gal. per hour and 118.8 gal. per hour. A good average
was 115 gal. per hour. Over 141 gal. per hour was considered excessive.
[Cassidy:2004:FE]: Oil consumption normally varied between
8 pints to 3 1/2 gallons per hour for a Pegasus engine.
</documentation>
<documentation>
"The two engine cut-out control levers were mounted either side of
the throttle box. The two inner engines were controlled by the
port side lever, while the starboard lever controlled the two
outer engines.", [Cassidy:2004:FE]
</documentation>
<documentation>
Engine automatic mixture system.
The Pegasus X.C. used a Claudel-Hobson A.V.T. 85E type carburetter with
variable datum boost control and automatic mixture control.
See [CAB:1943].
"The corresponding fuel:air ratios over the range are: Take-off, 1:10;
Rated, 1:11; Normal Cruising, 1:12; and Economical Cruising, 1:16."
