PRODUCTION BASIS
(All Models) Production Certificate No. 2 for engines produced by Pratt & Whitney (P&W)
Production Certificate No. 108 for engines produced by General Electric Aircraft Engines
(GEAE).
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.
NOTE 2: The normal 5 minute takeoff rating may be extended to 10 minutes for engine out contingency.

NOTE 5. PRESSURES
Fuel pressure limits Fuel pressure at the engine fuel pump inlet during operation shall be maintained at greater than or
equal to 5 psi above the true vapor pressure of the fuel, but less than or equal to 100 psi above
absolute ambient pressure, with a vapor/liquid ratio of zero. The maximum allowable pressure at the
fuel pump inlet after shutdown is 100 psig.

NOTE 9: During ground operations in icing conditions with an outside air temperature of +37.4°F / +3.0°C or less, periodic
engine run-ups must be performed to shed ice from the spinner, fan blades, and low-pressure compressor stators. Run-ups
must be to a minimum of 60 percent N1 at intervals not to exceed 30 minutes (and must include taxi-in, ground hold, and
taxi-out time). See EA GP7200 Operating Instructions Manual, P/N 5702515.
