3. MANUFACTURER’S EMPTY WEIGHT

The Manufacturer’s Empty Weight (MEW) is guaranteed not to exceed the value in Section 03-60-00 of Detail Specification ***, Revision *** including assumed changes to a new United Airlines configuration, plus one percent.

4. AIRCRAFT CONFIGURATION

4.1 The guarantees contained in this Attachment are based on the Aircraft configuration as defined in Revision B of the Detail Specification *** (hereinafter referred to as the Detail Specification) including assumed changes to a new United Airlines configuration. Appropriate adjustment shall be made for changes in such Detail Specification approved by the Customer and Boeing or otherwise allowed by the Purchase Agreement which cause changes to the flight performance and/or weight and balance of the Aircraft. Such adjustment shall be accounted for by Boeing in its evidence of compliance with the guarantees.

4.2 The guarantee payloads of Paragraph 2.7.1, 2.7.2, and 2.7.3 and the specified payloads of Paragraph 2.7.4, 2.7.5, and 2.7.6 block fuel guarantees will be adjusted by Boeing for the effect of the following on OEW and the Manufacturer’s Empty Weight guarantee of Section 3 will be adjusted by Boeing for the following in its evidence of compliance with the guarantees:

(1) Changes to the Detail Specification or any other changes mutually agreed upon between the Customer and Boeing or otherwise allowed by the Purchase Agreement.

(2) The difference between the component weight allowances given in Appendix IV of the Detail Specification and the actual weights.

5. GUARANTEE CONDITIONS

5.1 All guaranteed performance data are based on the International Standard Atmosphere (ISA) and specified variations therefrom; altitudes are pressure altitudes.

5.2 The Federal Aviation Administration (FAA) regulations referred to in this Attachment are, unless otherwise specified, the 737-900ER Certification Basis regulations specified in the Type Certificate Data Sheet A16WE, Revision 41, dated July 31, 2007.

5.3 In the event a change is made to any law, governmental regulation or requirement, or in the interpretation of any such law, governmental regulation or requirement that affects the certification basis for the Aircraft as described in Paragraph 5.2, and as a result thereof, a change is made to the configuration and/or the performance of the Aircraft in order to obtain certification, the guarantees set forth in this Attachment shall be appropriately modified to reflect any such change.

5.4 The takeoff and landing guarantees, and the takeoff portion of the mission guarantees are based on hard surface, level and dry runways with no wind or obstacles, no clearway or stopway, *** mph tires, with Category P brakes and anti-skid operative, and with the Aircraft center of gravity at the most forward limit unless otherwise specified. The takeoff performance is based on no engine bleed for air conditioning or thermal anti-icing and the ***. Unbalanced field length calculations and the improved climb performance procedure will be used for takeoff as required. The landing performance is based on the use of automatic spoilers.

5.5 The enroute one-engine-inoperative altitude guarantee is based on engine bleed for air conditioning with one pack operating. No engine bleed for thermal anti-icing is provided unless otherwise specified. The APU is turned off unless otherwise specified.

5.6 The speed, altitude capability, and cruise range guarantees, and the climb, cruise and descent portions of the mission guarantees include allowances for normal power extraction and engine bleed for normal operation of the air conditioning system. Normal electrical power extraction shall be defined as not less than a *** kilowatts total electrical load. Normal operation of the air conditioning system shall be defined as pack switches in the “Auto” position, the temperature control switches in the “Auto” position that results in a nominal cabin temperature of ***°F, and all air conditioning systems operating normally. This operation allows a maximum cabin pressure differential of *** pounds per square inch at higher altitudes, with a nominal Aircraft cabin ventilation rate of *** cubic feet per minute including passenger cabin recirculation (nominal recirculation is *** percent). ***.

5.7 The speed, altitude capability, and cruise range guarantees, and the climb, cruise and descent portions of the mission guarantees are based on an Aircraft center of gravity location of *** percent of the mean aerodynamic chord.

5.8 Performance, where applicable, is based on a fuel Lower Heating Value (LHV) of *** BTU per pound and a fuel density of *** pounds per U.S. gallon.

6.2 Compliance with the takeoff, landing, and enroute one-engine- inoperative altitude guarantees, the buffet onset portion of the altitude capability guarantee, and the takeoff portion of the mission guarantee shall be based on the FAA approved Airplane Flight Manual for the Model 737-900ER.

6.3 Compliance with the speed, altitude capability, and cruise range guarantees, and the climb, cruise and descent portions of the mission guarantees shall be established by calculations based on flight test data obtained from an aircraft in a configuration similar to that defined by the Detail Specification.

6.4 The OEW used for compliance with the mission guarantees shall be the actual MEW plus the Standard and Operational Items Allowance in Paragraph 03-60-00 of the Detail Specification.

6.5 Compliance with the Manufacturer’s Empty Weight guarantee shall be based on information in the “Weight and Balance Control and Loading Manual—Aircraft Report.”

6.6 The data derived from tests shall be adjusted as required by conventional methods of correction, interpolation or extrapolation in accordance with established engineering practices to show compliance with these guarantees.

6.7 Compliance shall be based on the performance of the airframe and engines in combination, and shall not be contingent on the engine meeting its manufacturer’s performance specification.
