The Engine Alliance (EA) is a partnership between GEAE and P&W. With respect to the benefits of type certification for production, GEAE and P&W function as licensees of EA. NOTES NOTE 1: Nameplate thrust values are defined at sea level static, standard pressure (14.696 psia), up to the flat rating ambient temperature, with 100% inlet recovery, no fan or compressor customer bleed, no horsepower extraction from BFE, and the production flight exhaust ((fan duct assembly comprised of left half, P/N 40113476-987G01, and right half, P/N 40113476-987G02) and primary nozzle (P/N L12192)). The nameplate ratings were derived using engine performance cycle simulations JV3.14.32.A and JV3.14.32.B for the maximum continuous and takeoff thrust ratings, respectively. For the GP7270, Electronic Engine Control Rating Plug (Part Number) 2122M76P05 provides increased Takeoff Flat Rating Ambient Temperature limits of 36°C / 97°F; the Sea Level Static Takeoff Thrust Rating is the same as Electronic Engine Control Rating Plug (Part Number) 2122M76P11. For the GP7272, Electronic Engine Control Rating Plug (Part Number) 2122M76P17 provides increased Takeoff Flat Rating Ambient Temperature limits of 34°C / 93°F; the Sea Level Static Takeoff Thrust Rating is the same as Electronic Engine Control Rating Plug (Part Number) 2122M76P08.
