B767 bleed fault (HPSOV)
Crew reports EICAS “L ENG HPSOV” + BLEED light illum during descent.
FIM tells me that this message will present itself whenever HPSOV is not closed when it has been commanded to close.
Question: Why would this message appear on descent? Shouldn’t HPSOV be open with engines at flight idle on descent?
(CF6-80C2 engines)
