Hi /diy/ I'm getting into PPG and I've found there is no such thing as a handheld fuel gauge. I was wondering if I could scavange my old scuba diving pressure gauge and do something with it. Any thoughts? Looks like pic related.
You will have issues getting a reliable reading, as the tanks tend to be small (in volume) and prone to fluid level changes due to flight attitude.
Most light aircraft, the fuel gauge is a suggestion at best, and fuel remaining is based on knowing the volume of fuel consumed at the desired power setting.
Use a watch.
Basically, except you have ~1 hour of total op, so your radius is 25 minutes with a 5 minute cushion.
Think flight time, and not fuel time.
Even though you're in a paraglider, you don't want to go wetfoot or hug a tree, because you thought you had a few more ml of fuel.
