Bank Angle Estimation Using Radar Data
The procedure designer’s toolbox calculating nominal track and protection areas is not entirely appropriate for determining the standard deviation of the trajectories, when designing a new departure procedure. The nominal track provides only a theoretical mean values to be shown on the chart but the aircraft cannot be expected to adhere to this route in a turn. Whereas protection areas are too wide and conservative estimates as they serve the purpose of providing adequate distance from ground obstacles under the worst conditions. This is why a new, radar based solution is needed to tackle this problem. The first step into this direction is to investigate the part of the route which infers the biggest uncertainty, the turn.
