Thanks SAM 2M - I drive a couple of BMW-RR 715's attached to a 717 - no charts for Min N1 or N1 if EPR fails - it seems strange to me that this has been allowed to get thru as I have no way of crosschecking that the power required is being attained.
Any other RR drivers out there that wish to comment - have bought it up with RR & Boeing - no reply yet.
