There are no complete study guides or reference books for candidates for the CPL(B) theory examinations to study. In this Help Page I will attempt to give references to questions in the COPB operational theory examination that are commonly answered incorrectly by exam candidates. I do not provide any guarantee that this material is correct […]
How to Convert Pressure and Altitude
The lift generated by a balloon varies with air pressure and temperature. This page looks at the relationship between pressure and altitude. Formalas for calculating the pressure at an altitude, and for determining the altitude of a nominated pressure level are provided. Online tools are also available for performing pressure and altitude conversions.
Propane
Commercial Propane is sometimes supplied as a mixture of propane and other Liquifed Petroleum Gases (LPG) such as butane, butylene and propylene. Autogas, in most parts of Australia, is a mixture of LPG gases including propane. LPG mixtures can be used as hot air balloon fuel provided adequate fuel pressure can be obtained.
Hot Air Balloon Physics
The physics of hot air balloon flight or how a hot air balloon fly whilst quite simple is often poorly understood. This article includes links to several published articles on hot air balloon physics.
Solar Balloons
The first pure solar balloon flight was made on the 1st May 1973 in the ‘Barnes Solar Firefly Tetrahedron’. This balloon was built from a spiral tube of fabric which was formed into a tetrahedron shape.
Balloon Terminology
Balloon Terminology All of those words and terms used by the ballooning community which might seem a little odd to an outsider.
