Are you an aspiring aerobatic competition pilot? Or perhaps you're interested in doing IAC-style aerobatics just for fun? Either way, AcroBox is the perfect app for you. Developed by Brad Benson, AcroBox is a free iPhone app designed specifically for aerobatic pilots.

AcroBox allows you to define the boundaries of a virtual aerobatic box that complies with the International Aerobatic Club's specifications and FAA regulations. With the help of VFR and IFR charts, you can ensure that your box doesn't encroach on federal airways or airport surface areas. The app also provides an aerial map to visually identify the box boundaries.

One of the standout features of AcroBox is its marker mode, which shows you exactly where the box markers should be placed. This is particularly useful if you're setting up a box for a club or competition event.

If you have multiple devices, AcroBox allows you to easily share box locations between them using iCloud. Additionally, you can share box details with other pilots via email. They will receive not only the coordinates of your aerobatic box but also a map image and a link to open the box in AcroBox or another popular flight planning app.

AcroBox is a must-have tool for any aerobatic pilot. Whether you're a seasoned competition pilot or just starting out, this app will help you stay in the box and ensure a safe and enjoyable aerobatic experience.
