Just Great!

I spent the cash and bought this app to have a back up nav tool where all the maps are stored on my iphones memory. This way I can use the gps to navigate even while my cellular chip is turned off. Therefore allowing me to get accurate direct to courses without using my cell phone data. When navigating on victor airways, this tool allows you to cross referencing your position with the aircraft VOR/DME.

A little pricy, but a great great great tool to have in the cockpit!
