Airclues
I'd be very suprised at that 'cause although it's possible to get a 9D to do that, the give away is the little orange lights on the EGT guages that come on at 915c. ............I suppose they could have snagged it for an EGT limited shortfall
1.3 instead of 1.6 EPR sounds a large error......
I believe the MK a/c had JT9D-7Q3, they have a (max) T.O EPR of 1.51 (standard day!) so to set it at 1.3 the t/l wouldn't be even half way up the 'gate', at that setting the 3.0 bleed would be barely closed.
