Abstract
A gas turbine engine fuel metering valve is configured to move within an operating position range having a first end position for establishing a first fuel flow rate, a second end position for establishing a second fuel flow rate, and an intermediate position located between the first and second end positions for establishing a third fuel flow rate. The first and second fuel flow rates are either both higher than or both lower than the third fuel flow rate.
