Detect-and-Avoid in Off-Nominal Situations for Supersonic Transport Aircraft in Upper Class E Airspace

This thesis researches potential failure conditions within supersonic and potential hypersonic aircraft. The most critical off-nominal situations have been identified to be Engine Failures, Rapid Decompression and High Altitude Radiation. Having in mind, current regulatory requirements as well as past operations of Concorde, potential locations for different speeds have been modeled to identify safe operational volumes. With an emphasis on the engine failure case as part of the thesis requirement, a potential first order approach to future DAA systems is described in order to add these models on top of current conflict resolution models.
