Corrected mass flow is used on engine maps because

  • A.It is required by regulation
  • B.One map covers every inlet condition
  • C.It is easier to measure than actual flow
  • D.It removes the need for a compressor map

Answer: B

Dividing by the appropriate functions of inlet temperature and pressure collapses all conditions onto a single chart. Without correction a separate map would be needed for every altitude and ambient temperature the engine might meet.
