When it comes to EFB apps for general aviation on the iPad ForeFlight seems to be the top of the heap in terms of users. One of the primary reasons why people say they prefer ForeFlight is the ability to overlay instrument approach plates over the sectional and enroute charts providing a great deal of situational awareness for instrument pilots when setting up and shooting an approach. Garmin Pilot has been steadily catching up to ForeFlight in terms of features, and with their latest pre-Oshkosh release they’ve now knocked that advantage off the ever-shortening list.
