Glider Instrumentation - Dragonnorth

This may not sound like much, but a 10 foot change in altitude corresponds to a pressure change of about 0.03% which means a volume change for the capacity of the same amount (Boyle’s Law). The air in a 450 ml capacity will expand by 0.03% when the glider rises 10 feet and this is just 0.14 ml ................
