Title:An Assessment of the Accuracy of Flight Path Data used in the Noise and Track-Keeping System at Heathrow, Gatwick and Stansted Airports
Description:This report describes a study that was undertaken to assess the accuracy of the flight path information contained in the London airports' Noise and Track Keeping (NTK) system. FDR data and data recorded on board an ILS calibration aircraft were used to check the NTK height and position (track) data. The results indicate that the NTK height data are on average accurate to within ±20 ft. Positional accuracy was found to be within 40 m. For the flights analysed, the study has shown no clear evidence of a consistent bias in the NTK height or position data at any of the airports.
