Together with the books Performance for Helicopters and Flight Planning for Helicopters, this book covers the EASA Learning Objectives in Flight Performance and Planning as stated in the EASA ATPL pre 2020 syllabus for helicopters. Emphasis has been given on providing the student with the basic physics knowledge required to be able to form the set of equations necessary to find the centre of gravity position.
From the books contents: Masses, Centre of Gravity, Reference System, Helicopter Mass Check, Floor Loads, Calculation of Traffic Load, Mass & Balance calculation for a Single Engine Piston Helicopter, Mass & Balance calculation for a Twin Engine Turbine Helicopter. The book has dedicated chapters for calculation of Mass and balance for:
-Single Engine Helicopters (the generic helicopter SEPH) -Twin Turbine Helicopters (the generic helicopter TETH)
Within the EASA countries SI units are supposed to be used. On the other hand, it is common to use US units in aviation. In this book SI units are used as first choice and US units when it seems logical to do so.
