This Technical Memorandum provides background information for ESDU 20007, entitled 'Aircraft Performance from Flight Test. Part 4: calibration of pressure air data systems. Sub-part II: GPS methods for determining true airspeed and wind speeds'.
An alternative procedure for determining wind speed when using Method 2 of ESDU 20007 is outlined.
The concept of indicated true airspeed, which is used in Method 4 of ESDU 20007, is also defined. Additionally, the differences between this term and both true airspeed and indicated airspeed are described.
