Features & Capabilities

A C-17 Duty Day Calculator for crews hauling Uncle Sam's stuff around the Globe.

This app will quickly help you calculate all applicable duty day restrictions in both Zulu and Local time zones. Simply enter the Alert, Show or Takeoff time and all Vol-3 restrictions will be instantly calculated for you. No more complex calculus at the end of your duty day.

BONUS: You can now add your own timeline to the app. Add your personal or squadron timeline to the latest addition. The tab can be tied to other calculator pages or work as a standalone tool for you planning your duty day.

It also includes a time calculator that allows you to calculate start, duration or end time when given the other two. Including the 781 decimal duration.

Hope you find it useful. My email is included if you have suggestions for improvements.

User Reviews

Decent app but some of the inputs are unreadable like another review said. Would be really helpful if this would be worked out.

Update: thanks for the quick fix! Wish we could get that hour back. The flying has been pretty great! Also, not sure if I did something to my settings, but the font is all white now and difficult to read. Love the calculator to help with everything we need to know. The only ask is that for bravo, “last beer” calculates wrong. It gives you 11 hours prior instead of 12. Would appreciate if you guys could update that so that it doesn’t get anybody in trouble after being tired and possibly not realizing the calculation is wrong. Otherwise, absolutely a great app!

Awesome app, but the new update screws up the color scheme when using an iPhone with “Dark Mode” selected in phone settings under “Display and Brightness”. Bravo is unreadable and just the input boxes are unreadable for the other pages but they are harder to read (white on light blue for airland). I think most people use dark mode these days so I’m sure I’m not the only one who would appreciate you looking into it. Thanks in advance!
