Jetplanner users?
Hi,
If there are experiences Jetplanner useres here, I would like your input on ETP related issues.
Sometimes we get ETP fuel which differs greatly on the out and back legs. As much as I know, since the times out and back are equal, so must be the fuel.
So where is this difference coming from?

Basically - JetPlanner uses average wind and temp forecasts at the selected levels on the great circle route, taking into account the diversion route and ground speed.
You may be flying a recipricle route, but once the everything has been factored in you will most likely find that the figures differ (as you already have)
As I said, thats a very basic view of why its happening - but if you want a (very) in depth explaination, look in yout Jetplanner users manual under POD/POA Commands............

plans,
From what I know, equal time should roughly give equal fuel. The difference we're getting is way too big.
merlin,
The guys at UK already gave up on this, and we are waiting for the answers from San Jose now. Just thought maybe someone here had this problem too.

ETPs for ETOP/EROPS with JP
Yup agree, has been a snag I know!!!!. I thought though that the guys in SJC had this sorted, but I admit not have spoken to them for some many months on this particular subject. Keep trucking the 4 holer with no self loading cargo!!!!
