It would have been nice if Flying ace 2, the previous reviewer, had upgraded to the most recent version of Garmin Pilot and actually knew something about the program before writing his quite off-the-mark review.
Garmin Pilot, in its most recent versions which were released BEFORE the date of his review, fully supports overlaying the approach chart right over the moving map display together with all of the weather and traffic overlays available if you have an ADS-B equipped airplane. It also supports the use of Jeppesen charts which is really only of use to IFR pilots.
Finally, it is certainly possible to have multiple windows on the screen. Right now, I have the moving map with weather, traffic and the Jeppesen approach plate on the left screen and, at the same time, an AHRS driven, HSI based panel on the right. These features have been part of Garmin Pilot since before the date of Flying ace 2s review.
Garmin Pilot is a fabulous program with a graphics engine superior to ForeFlight at the moment. Garmin came out with a data-driven map display long before ForeFlights newest release and it is still graphically superior. I expect ForeFlight to catch up soon. Thats why I use both in my IFR flying and keep them updated to their respective latest versions.
