Flight Load Factors: The First of Two U.S. Civil Aeronautics Authority Reports for the Information of Pilots

THE values of the load factors used in de‐signing an aeroplane are almost direct measures of its strength. They also affect the weight of a certain portion of the aeroplane structure. Although the percentage of gross weight that depends directly on the magnitude of the design load factors is not as large as might be supposed, it represents a considerable potential pay load on large aeroplanes and therefore warrants careful consideration of the basic question: What is the minimum load factor consistent with safety?
