User reviews

Can’t even figure fuel burn

Defective app hangs up you cannot enter a basic minutes and seconds. 3 adults tried. Cannot enter 00:08:56. Aka 8 minutes 56 seconds. Won’t let you. The very first thing I wanted to calculate is how much fuel I’d burn in that time at 8 gph couldn’t do it

Response from developer

Thanks for the report, and sorry for the frustration. You found a real bug: when Duration was set to HH:MM:SS, the app dropped the leading zeros, so a time like 00:08:56 couldn't be entered. That's fixed in version 1.0.17, which has been submitted and should be available within about 72 hours. Once you install the update, Duration accepts leading zeros on Fuel Burn, Ground Speed, and ETA. If it's still giving you trouble after updating, email support@entireflight.com and we'll sort it out. If the fix works for you, we'd appreciate an updated review. But remember we need to wait for the update to go through. Thank you for your patience, the rest of the app should be working ok. we truly appreciate your business EntireFlight

Must Have Pilot App

As a CFI, I wish I had this back when I was getting my own Certificates/Ratings.
This app seems to be built by pilots!

Amazing

I really love this e6b app it’s great for getting quick calculations in flight but also great test prep. I love that I could build an entire cross country nav log and export it for printing. Also the interpolation feature is a game changer from interpolating performance charts
Awesome app!
