Book Description
The Fort Worth Division of General Dynamics has been heavily involved with failure-tolerant flight control systems for almost 20 years through production of the F-111 and the F-16. The need for survivability after failure is most obvious on the F-16, which has the world's first production fly-by-wire flight control system. Fly-by-wire is an absolute necessity on the F-16 because the aircraft was designed to be statically unstable and cannot be controlled without the artificial stability provided by the flight control system. Because of difficulties in analytical definition, several external factors may not be included in the failure analysis of flight control systems. These factors, although not directly a part of the flight control system, can render redundancy useless if not considered. Examples of these external factors are pilot interface, ground maintenance, structural resonance, environmental conditions, indirect electrical hazards, and other system failures. These factors are not unique to the F-16 but are common to all aircraft with fly-by-wire flight control systems. This paper discusses examples of how several of these factors manifested themselves in the development of the F-16 and how the F-16 flight control system has evolved to minimize their effect. One of the mose significant evolutions to aid in the isolation and resolution of problems is the time sequenced data provided by the F-16 maintenance memory.

Book Description
The F/A-18E/F Super Hornet is a growth version of the F/A-18 A through D model 'heritage' Hornet, first fielded in 1983. Sone of the primary design goals for the Super Hornet, included increasing the range, providing greater weapon loading flexibility increasing carrier landing bring back weight and improving survivability. Improving the survivability was addressed in various ways including reductions in radar cross section expanded self-protection systems, and enhanced maneuverability. The heritage Hornet, was the first tactical aircraft in the world to fully exploit high Angle of Attack (AOA) maneuvering in the air combat environment. The heritage Hornet, is widely known for its ability to attain and maintain high angles of attack providing the pilot with a distinct advantage in the low airspeed, high AOA arena. Hornet pilots have achieved great success by simply 'intimidating' threat aircrews. This intimidation can cause threat pilots to make grave tactical maneuvering errors in this flight regime. Despite these capabilities the heritage Hornet, has had a history of inadvertent departures from controlled flight mostly in the low speed high AOA flight regime. Heritage Hornet, pilots must always maintain situational awareness of their aircraft state (aircraft store loading in combination with perceived yaw rate and sideslip AOA and airspeed) to ensure they do not inadvertently cause one of these departures. One of the primary goals for improving the Super Hornet's maneuverability included addressing the total systems design and integration of the Flight Control System (FCS), Operational Flight Program (OFP), and Mission Computers (MC) in order to optimize the control effectors in all phases of flight, including failure modes and battle damage.

Book Description
Annotation Bridging the gap between academic research and real-world applications, this reference on modern flight control methods for fixed-wing aircraft deals with fundamentals of flight control systems design, then concentrates on applications based on the modern control methods used in the latest aircraft. The book is written for practicing engineers who are new to the aviation industry, postgraduate students in strategic or applied research, and advanced undergraduates. Some knowledge of classical control is assumed. Pratt is a member of IEEE and is UK Member for AIAA's Technical Committee on Guidance, Navigation and Control. Annotation c.
