A compressed air supply system according to one aspect of the present disclosure is a compressed air supply system that extracts compressed air from a gas turbine engine and supplies the compressed air to an air conditioning pack of an airframe. The compressed air supply system includes: a low-pressure bleed air port that extracts the compressed air from an upstream side of a high-pressure compressor; a high-pressure bleed air port that extracts the compressed air from a downstream side of a front-stage portion of the high-pressure compressor; a main pipe extending from the low-pressure bleed air port toward the air conditioning pack; an auxiliary compressor that is located at the main pipe and increases pressure of the compressed air; a high-pressure bleed air pipe that couples the main pipe to the high-pressure bleed air port; a high-pressure bleed air valve located at the high-pressure bleed air pipe; and circuitry that opens the high-pressure bleed air valve when the circuitry determines that an insufficient pressure state occurs, the insufficient pressure state being a state where with the high-pressure bleed air valve closed, outlet pressure of the main pipe is not maintained within a required pressure range of the air conditioning pack.
