I do apologise for the delays but we are finally coming into the home straight with the update [sf].
Why the goalposts keep moving? The feature richness of IF, the higher quality requirement of the update, and the way certain functions coexist within the program, have come together to necessitate keeping the product under further construction. To save time there have been no production builds for previewing so far. I will make preview versions available as soon as possible. I am very grateful to those of you helping in the background and awaiting previews.
This is your IF and I'm working non stop to provide the functions you need to progress with flight simulation.
In the upgraded version, the acquisition of NavDataPro and Navigraph data sets into the program has been dealt with in such a unique way and provides such unique functions, that IF is unmatched handling AIRAC cycle data with respect to it's coexistence with your FSX as it stands with your addon scenery and airports, and aircraft, more soon (Upgrade license required).
FSX weather is full of compromises but in the update [sf], IFs weather and dynamic environment systems completes the original design goals for the product. I'm having a job not flying.
More soon.
