Fuel Planning Figures

Greetings all,

I fly an S76A++ and the standard fuel planning figures previously used were 130TAS and 580LB/Hr.

I have recently been advised to cruise at 94% N1. I can't imagine it will be a big change but I was wondering what flight planning TAS/FB this may be and if I can find out other than flying that figure.

I was wondering if anyone else does this and what TAS/FB planning figures they use for generic planning? In the Performance charts there is a line for cruise power but I have been told this is based on 98% N1 is this correct? How do you use the chart at 94% N1?

Excuse my ignorance if this is obvious but I have missed it somehow. Curious to know what other flight planning figures people use.
