Bobby,
I am sorry I was not clear
and the reason was that I was not clear myself.
The injector disable
switches are for in case you lose an injector in flight and the engine starts
to run on only one rotor. You can disable either of the primary or
secondary injectors which will take the failed injector out of the circuit.
Tracy says you should test this to make sure that it works. That
is where my question came from. You can only test the disable switches
when the engine is not staged. If the engine is staged, and you turn off
the primary injectors, the engine will die because the secondary injectors are
not running, and if you turn off the secondary injectors, the engine will run
rich because you turned on the cold start but the secondaries were not running
anyway.
I am not sure what would
happen if you lost a primary injector in flight, disabled the primary
injectors, then reduced power to the staging point in order to land??? I
suspect all would get quiet! :>(

Bill,
I’m not sure I
understand the question. If your referring to my “center off switch
position” it’s not used in flight. Intentionally anyway J
It’s used to shut down the engine. Primary injector switch of course.
Same switch used for both primary and secondary injectors.

Changing the subject a
minute…How do you disable the secondary’s when the engine is
staged?? They are not running anyway???
