Hi Dave-

I'd like to match the AIRAC cycle that exists in the Flight1GTN with the same in P2ATC so when I export, I don't keep getting the 'waypoint not found' in the GTN. :>)

I see you can download old versions at Navigraph but not certain P2ATC will accept an older version and have it work. Is this possible?

Thanks,

Mark

As long as the desired AIRAC cycle is the same format as the current data, it should work.  If you get data errors, it would likely be because the cycle is so old it is not in the current format.

Thanks. The trick now is trying to find them which has led down a long and dark path. ☹️
