JAR ATPL Training

JAR Ref 031: Mass and Balance

This series of texts from Atlantic Flight Training (UK) is the complete course of study for the JAR ATPL set of exams. These "JAR OPS" texts are study guides and are not to be used as operational references. The philosophy of Atlantic Flight Training (AFT) is to train pilots to fly under JAA jurisdiction, not to simply pass the exams.

The JAR-ATPL candidate may sit the exams at any JAA-approved examination center. All candidates are required to bring a copy of the Student Route Manual, JAR VFR Supplement, and a JAR-compliant E6-B computer.

JAR Ref 031: Mass and Balance

Mass and Balance (otherwise known on the planet Earth as "Weight & Balance") covers the factors governing the loading of an aeroplane to ensure that the longitudinal centre of gravity and mass are within the structural and performance limits. This volume has been written to give you a good understanding of the effects of adding or subtracting a mass from an aeroplane, or moving a mass within an aeroplane, through the use of explanation and worked examples. It enables you to understand the importance of ensuring that the aeroplane for which you are responsible is correctly loaded and trimmed for flight and ground operations. The JAR-FCL has adopted the UK CAA Civil Aviation Publication (CAP) 696 for Mass and Balance examination purposes. This volume details three generic aeroplanes; single engine piston aeroplane, a multi-engine piston aeroplane, and a medium range twin jet.

Trivia:

The European tendency to be over-academic in some of these matters is apparent when referring to weight as "mass", which is a term used by physicists who try to measure objects anywhere in the entire universe. Don't feel guilty: airplanes only exist on earth, and it's entirely appropriate to use the term "Weight" as long as you're not flying in outer space. For additional clarification, check with any astro-physicist.
