hi all,
my questions are:
1. in 'emergency load' mode, why does AP2 remain available? would it be the same if AP1 remained available and not AP2?
ANS 1: no difference..ap2 remains on cz emergency bus 1 powers up inv 1 and inv 1 powers up AP2..
2. if eng no2 overspeeds, say its n2 103 %. no1's n2 is 100%. now the Nr (rotor RPM) would match no1's n2 as per the maintenance manual. how would the clutch (the free wheeling device) allow the low RPM (100%) to be matched with Nr against a higher RPM (103%)..
