## What is KC?

A KC-46 Duty Day Calculator for crews passing Uncle Sam's gas 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.
