Hi Bevan
I have the ipad and the NAIPS and OzRunways, but I have to tell you the planning tool is not that flash. I even removed it
Maybe I did not use it right, and for an IFR flight an interface with NAIPS and printing needs to be a priority.
Maybe I am wrong, and happy to be shown the errors of my ways, but it needs a lot of work for some folk to find useful.
For VFR ops(especially OCTA) it may well be all you need.
Cheers!
