Would it be, or is it already, possible to enter comments about specific airports?
For example, I thought I knew the frequency of a local private airport that was having a public fly in today. When I tried to look it up in iFly, or the internet (luckily I still had cell service) it wasn't displayed anywhere. I called the Tracon that vectored for the area, they had no idea. Finally, someone on the wrong nearby frequency, set me straight. But it would be nice to have a place to enter unique information we've discovered about any number of random airports, and recall that information when we access the airport information through iFly. This custom information should persist through the regular updating of FAA airport information.
