<P><EM>Airplane Performance on Grass Airfields</EM> presents an experiment-based approach to analysis and flight testing of airfield performance on grass runways. It discusses improvements for operational efficiency and safety of these airfields.</P><P></P><P>The book analyzes the interaction between the landing gear wheels and the surface of a grass runways during both takeoff and landing. Considering the ground performance of an aircraft on a grass runway, the book covers test methods and devices for measuring performance and introduces an information system for the surface condition of grass airfields: GARFIELD. The system is based on a tire-grass interaction model and uses digital soil maps, as well as current meteorological data obtained from a weather server.</P><P></P><P>The book is intended for researchers and practicing engineers in the fields of aviation and aircraft safety and performance.</P>
