Automatic Dependent Surveillance - Broadcast Enabled, Wake Vortex Mitigation Using Cockpit Display

Wake turbulence has the potential to cause accidents during the landing phase of flight. This thesis work documents the development and testing of a prototype cockpit display to help pilots avoid this wake turbulence using ADS-B technology. Several landing profiles of the wake generating aircraft and the trailing aircraft were created using computer simulations to generate the synthetic data. A tracking algorithm was developed to compute the altitude of the leading aircraft to be displayed in the altitude strip of the cockpit display. This algorithm will search for all the points of flight data of a leading aircraft, within a predefined region near a trailing aircraft. This flight data is projected on a primary or multifunction display to create an imaginary scenario and tested for data acquisition and transmission from one aircraft to another. The parameters and the number of bits that are necessary to transmit these data via the ADS-B for avoiding the wake turbulence, especially in the case of busy airports are documented. As a final step, necessary hardware was installed in two GA (General Aviation) aircraft and a flight test was performed. The flight-tested prototype successfully provided the pilot of the trailing aircraft with intuitive information on a multifunction display to avoid wake turbulence.
