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!  :>(
