## What is FredRest?

Input the flight's start time, and time, and the transition time (length of time allotted between rest blocks for pilots to switch places). Then select whether there will be a total of 3 or 4 rest blocks.

If there are 3 rest blocks, simply hit the "Calculate" button and your crew rest schedule will be created for you.

If there are 4 rest blocks (2 shorter blocks and 2 longer blocks), then first select whether you would like to specify the length of the short block, the length of the long block, or the ratio between the short and long blocks (short = __% of long). Then input the value, and finally select one of four possible sequences of short and long blocks. Hit "Calculate" and the app will do the rest, displaying exactly what your crew rest schedule will be.
