i've been an observer of this site for some time now but until recently haven't posted. i'm looking to find out the correct procedure for when
start valve will not close after main engine start on airbus or boeing aircraft.
training and run-up guide at my carrier tells me to isolate pneumatics on effected engine and shutdown.
isolate pneumatics, ok, but why is there a need to shutdown right away?
why shouldn't i be able to continue my run (with the particular engine isolated), complete my ground checks as required, then shutdown?
heck, i could even call our storeman on my mobile and ask him to deliver a new start vlv while i complete my run.
saves time and returns the aircraft back to service quicker!!
of course, i would never contravene company policy
feedback appreciated
