In the gas turbine engine business, engine operability is the ability of the engine to operate without compressor stall or surge, combustor flame-out or other power loss. Operability engineers work in the fields of engine and compressor modeling, control and test to ensure the engine meets its ignition, starting, acceleration, deceleration and over-speed requirements under the most extreme operating conditions.
