AcroBox 2.0 Available

[ChiefPilot]

Interested in aerobatics and looking for places which might be potential locations to practice your IAC routine?

I wrote this app last year to simplify the process of finding potential practice boxes and it worked pretty well. This year, I've updated it with support for more devices (iPad Pro, etc.) and additional sharing features. For example, if you have a box that you like, you can instantly share it with someone else via AirDrop - no WiFi setup, no email, no texts - just share it and it opens in AcroBox on their phone or iPad.

As before, it still allows you to examine a location against both VFR and IFR charts to ensure separation from airways, special use airspace, etc. and it now also has street maps available in case it's helpful to provide an approximate address for someone judging from the ground.

A couple of quick screen shots showing the box used at Newton, KS last year for the Aces High contest put on by IAC Chapter 119. The aerial view shows the box, the boundaries, and the judges area, while the IFR low chart shows conflicting airways (requiring a waiver, which they had).

... ...

As always, the app is completely free (no ads, no unlock fees, etc.) - aviation is expensive enough as it is.

Great app to draw a box anywhere ��! I use it to help locate landmarks like Brad pointed out using the earth view. Thanks for the contribution!!!!
Now if I can just learn to stay in the box...

Thank you so much Brad!

I just updated the app. It's fantastic!

Thanks Brad. I have a question about checking for interference with airways. I am assuming that the shaded area represents the 4 mile separation needed from an airway centerline. Is that shaded area from the edge of the box or the center of it? Thanks

Thanks :-) The coolest thing that has happened from this app for me has been talking with someone about aerobatics at a practice day/contest/AirVenture and having them pull out their phone to show me "this cool app I found for aerobatic boxes".

It's from the center of the box, and it's actually slightly more than 4nm to account for the entire box plus the error present in tiled geo-referenced charts. It's a bit on the conservative side, but if the airway etc. is not in the shaded area then you're good to go.
