A C-130 Duty Day Calculator for crews hauling Uncle Sam's stuff around the world.

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.

NEW: 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.

Needs proofing

You're welcome Herk drivers... I'll eat my $2 for you. The tac day and training day should both be show+12, but for tac day it's doing show+14 in the actual calculation. Also, should add an option to use cold wx soe, where the time value can be specified in user options.
