This paper presents the process of the Loads Validation Flight Tests performed at IAI for the G280 super mid-size business jet. The G280 is the latest business jet developed in IAI and although it is based on the fuselage of its predecessor, the G200, it features a totally new wing, empennage, more powerful engines and state of the art fly-by-wire systems integrated into the aircraft flight control system. The Loads Validation Flight Test program is used to verify the data and methods used for Loads Analysis and is part of the Loads Substantiation program of any newly developed aircraft. Although large efforts are made to maximize the accuracy of the different type of loads analyses, current airworthiness regulations require that loads for new aircraft models be validated by means of flight tests. The Loads Validation Test Program performed for the G280 was unprecedented in IAI due to the scope of the measurements and the complexity of the dedicated calibration test performed on prototype s/n 2002. During the G280 Flight test campaign, 401 exercises were dedicated to Loads Validation. These exercises were completed in 33 flight tests, mostly of prototype 2002 during the period of October 2010 to January 2011. This paper will present the different phases of the Loads Validation program, including definition of measured loads, instrumentation, calibration of the instrumentation, flight conditions, examples of results for the various load types measured and conclusions regarding the validity of the methods and data used in the Loads Analyses.
