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.
