If Compressor Discharge pressure line disconnected from a turbofan engine,what will happen?

Question

During start of the engine CDP line disconnected,will it hung start? or During cruise the line disconnected the engine will come to idle.Out of thease two situation which one is true?Answer is expected by Aviation expert only...

Answer 1

I think the first situation is much more true. I will not claim authority on this but I do remember what my co-worker told me when there is a pilot remarks re: throttle lever staggers in a 747-200, when one or two throttle levers lag behind or slow to accelerate, one must remove and clean CDP lines.

Answer 2

depends whether youre talking about an hp or lp line. a low pressure disconnect is no problem. an high pressure disconect will cause power loss and if it happens inside the engine cowl it'll likely set off a false fire alarm. hot stuff you see.
