### 5/5 — great app

*2018-04-27*

another best app and i would love to see updates continue through all ios releases

### 1/5 — Calculations are wrong

*2017-12-28*

At least in the flight planning sections all the flight time and fuel calculations are WAY off.

### 4/5 — Very helpful!

*2016-01-09*

Great app for visual learners. Good tool for a CFI to keep in their back pocket.

### 4/5 — Very Nice

*2014-03-22*

Great explanation of each calculation.  Can't wait for more.

### 2/5 — New version screwed up

*2013-04-01*

Under the TOUR, the icons do not match the descriptions. The fields need more description of what exactly is need for the type of answer. No where is there any place to set your airplanes defaults even though it reads that one screen feeds another, this does not seem to always work.

### 5/5 — Love the new UI

*2013-03-28*

This app has been updated to use the slider menu from the side. Really makes navigating the app so much easier!

I've got too many E6B apps (it's a personal problem, don't go there:) this app has a very unique approach.
At first I didn't like the graphics that goes along with each solution but now it helps me visualize the problem!
e.g. Best Rate of climb vs Best Angle has a very nice pic which is easy to see the difference!
Plus Double Dog Studio does a good job with there apps!

### 5/5 — Awesome

*2013-03-25*

As a flight instructor this is one heavily used app. Well done its about time you can get it all in one app!

### 5/5 — Excellent

*2012-09-27*

Must have for ipad.

### 5/5 — Great pilot tool!

*2012-05-12*

Excellent cockpit tool...easy to use for quick computations in-flight as well as on the ground.

### 5/5 — Nicely done! ==UPDATE==

*2012-04-18*

Very useful and handy app! The variety of possible calculations gets the pilot to fly new and unknown maneuvers, such as the pivotal altitude (I really didn't know about before)!

Of course there are things to improve, e.g.
1. I'm missing a settings-page where you can preselect your personal default units, since Europe pilots usually fly with KG and LTR, or TMG (Touring Motor Glider)-pilots use meters or kilometers. With that page you wouldn't have to always change units on every calc-page.
2. There are CG-calcs for 2- and 3-row aircraft, what about the 1-row?
3. VOR-calculations?

Go on with that great app!

EDIT:

Dear developer team,

Thank you very much for updating this app according to almost all of the above requested!!
The last missing star is for you, thanks again!!

Happy landings from GER... ;o)
