Kind of confusing, but does what it says…

I met the author at OSH, AirVenture and was sold. This data should be in all EFBs. A lot of information in a small space. Needs a iPad version.

No Brainer

This is a Fantastic tool for your flight/Simulator flying. The pricing at $1/month is a Super Bargin. If you ever wanted a quick way to see and use your aircraft’s performance, this is IT!!
