## What is Frag Calc?

Calculator application for tanker pilots and operators. Quickly calculate the amount of fuel available to offload to receiver aircraft, taking into account bingo fuel and offstay time. Add multiple offload brackets with custom comments/call signs. Fuel units can be changed between tonnes and thousands of pounds.
A slider allows the operator to choose between max offload, latest off-station time, and everything in between.
