Actually Efass is free to use but puts up a nag message after a couple of weeks with an option to buy. The message counts down for up to 2 or 3 mins then lets you in. Buying will remove that. It's a very good flight/fuel planner that I use now instead of

Pfpx which is also great but probably too elaborate for my uses.

 

I can thoroughly recommend it.

One more question,

 

It can be run on another PC right ? Because I tested it on a notebook , and I saw 30 / 40% CPU Usage used by EFASS process... are you running both sim and EFASS on the same machine ?

I'm pretty sure that if you want to use the weather engine, you need to run it on the same computer as X-Plane.

 

And as a recommendation. Use it for the full 14 day free trail before you decide to buy it.
