Reduced Thrust B737-200(Performance)Question
Hi
I have a question, this is for a B737-200.
Sometimes when weight for take-off is low , we reduced thrust until to the actual weight , e.g. a take-off at 26C reduced to almost 43C and then we read the speeds and EPR required at 43C
Now someone decides to take speeds at actual weight but take-off EPR is measured as average, that is in between 26C to 43C , somewhere in between, around 32C .
Its claimed that rotation is much earlier this way and its helpful for rough runways, now Im asking , is this true ?
Do you get airborne earlier if EPR is higher than whats shown on actual weight ?
