Electronic Engine Control (EEC) software version SCN11G and earlier versions have maximum permissible exhaust gas temperatures 635łC (actual and indicated) for takeoff (5 minutes) and 610łC for maximum continuous. To provide adequate margin for consolidated bump rating operation, EEC software version SCN11H to SCN12B/N can provide maximum permissible EGT of 640łC actual (635 łC indicated) for non-bump takeoff, 650łC actual (635łC indicated) for consolidated bump takeoff, and 615łC actual (610łC indicated) for maximum continuous. EEC software version SCN12C provides a maximum permissible EGT of 650oC actual (635oC indicated) for takeoff and 625oC actual (610oC indicated) for maximum continuous with or without consolidated bump usage. The noted engine ratings and limits are controlled by EEC P/N and Data Entry Plug (DEP) P/N, and are implemented by specific Service Bulletin instructions only. The engine data plate also reflects the engine ratings and limits configuration. The indicated vs. actual EGT values are controlled by EEC software. NOTE 19. Supplemental Type Certificate SE636NE approves installation of a fan thrust reverser and exhaust system (P/N 740D8018) on the V2500-A1 series models. The thrust reverser/exhaust system consists of the thrust reverser, common nozzle assembly, tail plug, and pylon installation kit, and consists of parts listed in IAE Thrust Reverser Type Design Bill-of-Material, Serial No. N0009.
