Propulsion
by an engine interferes with the performance and stability of an
aircraft. As a result, propulsion can affect the aircraft’s safety as
well as the economics of its fuel consumption. After all, differences
of as little as 0.5% in fuel consumption can have substantial effects
on the operational cost of an aircraft. Precise measurements of the
effects of propulsion are therefore of crucial importance.
