Today's general aviation aircraft are being
retained in services well beyond the lifecycle
anticipated by their manufacturers. While some
airframe aerodynamic refinements can be
applied to improve performance, available
engine technology is stuck in the pre 1950s.
This lack of advancement is failing to meet
modern environmental requirements
particularly regarding fuel efficiency, noise and
air pollution, as well as the overdue elimination
of leaded fuels.
This paper is concerned with the
application of Systems Engineering (SE)
methodology to the need for maintaining,
upgrading/retrofitting the world’s GA aircraft,
and more particularly their engines.
Discussions in this paper focus on using SE
techniques to define needs that leads to
optimising the confidence and predict-ability of
forecast demand.
