VFR Diversion math practice

You are diverting to an alternate airport 65 nautical miles away. You have just traveled 10 nautical miles in 5 minutes and 33 seconds. What is your ground speed? What is your ETA? How much fuel will you have left? What is your remaining endurance?

Every pilot needs to be able to calculate these items while flying the aircraft and without a calculator. Doing it accurately will make you a safer pilot.

Practice your VFR diversion math with this easy to use application. Shake up new random values for ground speed check, distance to alternate and starting fuel. Make your ETA calculation. Hold the button for the answer. Did you get within 10 minutes without going over? The closer you get the higher you score. Watch your score get better as with practice!

Set max fuel, speed, and burn rate parameters for your aircraft. All settings are units agnostic so you can use miles, kilometers, or nautical miles for distances or gallons, pounds, litres etc for fuel.
