Copilot is an elegant application that does what it says it is going to do. The Intuitive user interface stores and allows easy editing of flight plans. I get to quickly determine if a flight is possible and safe, then enter current wind information just before takeoff and make sure it is still safe. When my passengers show up, I can quickly check the loading and be ready to fly with confidence. Then I get a kneeboard printout for the cockpit! Since I fly to remote airports, I don’t need connectivity to use this app, which is GREAT. I don’t understand reviewers that are upset that an app doesn’t do what it didn’t say it would do. Those reviewers that want downloadable AFD information can have that for $75 PER YEAR. Weather is available with lots free apps, but only when connected.
