Abstract
This paper reports the latest progress in the development of a database-driven safe flight envelope prediction system. By building up a database containing safe flight envelopes of different damage and fault scenarios, the challenges associated with online flight envelope prediction can be circumvented. The database is designed for different flight conditions at which the flight envelopes are computed. Both longitudinal and lateral envelopes are computed via the level set method, which shows obvious shrinkage between damaged and undamaged aircraft. It is found that by interpolating between two retrieved envelopes in the database, more accurate results can be achieved.
