Aircraft Systems

This third edition of Aircraft Systems represents a timely
update of the Aerospace Series' successful and widely
acclaimed flagship title. Moir and Seabridge present an in-depth
study of the general systems of an aircraft - electronics,
hydraulics, pneumatics, emergency systems and flight control to
name but a few - that transform an aircraft shell into a living,
functioning and communicating flying machine. Advances in systems
technology continue to alloy systems and avionics, with aircraft
support and flight systems increasingly controlled and monitored by
electronics; the authors handle the complexities of these overlaps
and interactions in a straightforward and accessible manner that
also enhances synergy with the book's two sister volumes,
Civil Avionics Systems and Military Avionics Systems.

Aircraft Systems, 3rd Edition is thoroughly
revised and expanded from the last edition in 2001, reflecting the
significant technological and procedural changes that have occurred
in the interim - new aircraft types, increased electronic
implementation, developing markets, increased environmental
pressures and the emergence of UAVs. Every chapter is updated, and
the latest technologies depicted. It offers an essential reference
tool for aerospace industry researchers and practitioners such as
aircraft designers, fuel specialists, engine specialists, and
ground crew maintenance providers, as well as a textbook for senior
undergraduate and postgraduate students in systems engineering,
aerospace and engineering avionics.

Lan Moir After 20 years in the royal Air Force as an
engineering officer, Ian went on to Smiths Industries in the UK
where he was involved in a number of advanced projects. Since
retiring from Smiths he is now in demand as a highly respected
consultant. Ian has a brad and detailed experience working in
aircraft avionics systems in both military and civil aircraft. From
the RAF Tornado and Apache helicopter to the Boeing 777, Ian's work
has kept him at the forefront of new system developments and
integrated systems in the areas of more-electric technology and
systems implementations. He has a special interest in fostering
training and education in aerospace engineering.

Allan Seabridge was until recently the Chief Flight
Systems Engineer at BAE Systems at Warton in Lancashire in the UK.
In over 30 years in the aerospace industry his work has latterly
included the avionics systems on the Nimrod MRA 4 and Lockheed
Martin Lightning II (Joint Strike Fighter) as well as a the
development of a range of flight and avionics systems on a wide
range of fast jets, training aircraft and ground and maritime
surveillance projects. Spending much of his time between Europe and
the US, Allan is fully aware of systems developments worldwide. he
is also keen to encourage a further understanding of integrated
engineering systems. An interest in engineering education continues
with the design and delivery of systems and engineering courses at
a number of UK universities at undergraduate and postgraduate
level.
