  7. Abstract:
  8. This work presents a novel approach to redefine a safe aircraft based on systems engineering fundamentals. Its aim is to prescribe a “Safe-Functional-Aircraft” instead of currently used procedures that is based on “Physically-defined-Safe-Aircraft”. The current work is much more consistent with increasing number of flights. It basically suggest that any aircraft that can complete its mission should not declare emergencies due to any physical malfunction. With proper simulations, have investigated the feasibility of replacing a “physically safe” aircraft with an “operationally/functionally safe” one. The process makes use of well-known documents such as FTA and FMEA ; which are produced during RDTE phases of the project. To demonstrate the feasibility of the concept, two well-known major incident involving B-747 and B-767 have been thoroughly investigated. We have clearly shown that the proposed method can alleviate both pilot and controllers’ workload in perceived emergencies. Further studies are needed to develop an “expert system” to advice the pilot or even to assume control of the aircraft as a mode of the existing autopilots
