EPR basics
I've never used an EPR and would like to know the following:
Is it front over rear or vice versa?
If it is front over rear this would explain (I think) why the ram effect on take off increases EPR (as I'm told it does). But how can it be that you set 1.2 or 1.3, I would have thought that the pressure at the front was less than the rear and hence the ratio would be less than 1.0 !?
Please help.
