(2) The difference between the seat weight allowances to be incorporated into the Detail Specification and the actual weights.

4	GUARANTEE CONDITIONS

4.1

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

4.2

The Federal Aviation Administration (FAA) regulations referred to in this Attachment are, unless otherwise specified, Code of Federal Regulations 14, Part 25 amended by Amendments 25-1 through 25-117, plus 25-128 except as noted in FAA Issue Paper G-1, subject to the approval of the Federal Aviation Administration.

basis for the Aircraft as described in Paragraph 3.2, 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.

4.4

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 anti-skid operative unless otherwise specified. The takeoff performance is based on an alternate forward center of gravity limit at *** percent of the mean aerodynamic chord unless otherwise specified. Engine-inoperative takeoff thrust is limited to *** minutes unless otherwise stated. The takeoff performance is based on engine power extraction for normal operation of the air conditioning with thermal anti-icing turned off and *** unless otherwise specified. 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.

4.5

The cruise range guarantee 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 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. No engine bleed for thermal anti-icing is provided unless otherwise specified. ***unless otherwise specified.

4.6

The cruise range guarantee and the climb, cruise and descent portions of the mission guarantees are based on an Aircraft center of gravity location, as determined by Boeing, not to be aft of *** percent of the mean aerodynamic chord.

5.6

In order to comply with the mission payload guarantees of paragraphs 2.4.1, 2.4.2, 2.4.4 and 2.4.5, Boeing may elect to increase the Maximum Takeoff Weight from ***pounds up to as much as ***pounds. Any such increase in Maximum Takeoff Weight would be an exclusive remedy for this purpose and would be in lieu of all other rights, remedies and claims Customer may have associated with the mission payload guarantees.

5.7

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.

Such adjustment shall be accounted for by Boeing in its evidence of compliance with the guarantees.

3.2		The guarantee payloads of Paragraph 2.4.1, 2.4.2, 2.4.4, and 2.4.5 and the specified payloads of Paragraph 2.4.3 and 2.4.6 block fuel guarantees will be adjusted by Boeing for the effect of the following on OEW 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 seat weight allowances to be incorporated into the Detail Specification and the actual weights.

4		GUARANTEE CONDITIONS

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

4.2		The Federal Aviation Administration (FAA) regulations referred to in this Attachment are, unless otherwise specified, Code of Federal Regulations 14, Part 25 amended by Amendments 25-1 through 25-117, plus 25-128 except as noted in FAA Issue Paper G-1, subject to the approval of the Federal Aviation Administration.

4.4		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 anti-skid operative unless otherwise specified. The takeoff performance is based on an alternate forward center of gravity limit at * percent of the mean aerodynamic chord unless otherwise specified. Engine-inoperative takeoff thrust is limited to five minutes unless otherwise stated. The takeoff performance is based on engine power extraction for normal operation of the air conditioning with thermal anti-icing turned off and *** unless otherwise specified. 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.

4.5		The cruise range guarantee 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 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. No engine bleed for thermal anti-icing is provided unless otherwise specified. The * unless otherwise specified.

4.6		The cruise range guarantee and the climb, cruise and descent portions of the mission guarantees are based on an Aircraft center of gravity location, as determined by Boeing, not to be aft of 28 percent of the mean aerodynamic chord.

5.4		Compliance with the cruise range guarantee 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.

5.5		The OEW used for compliance with the mission guarantees shall be the actual MEW plus the Standard and Operational Items Allowance in Paragraph ***of the Detail Specification.

5.6		in order to comply with the mission payload guarantees of paragraphs 2.4.1, 2.4.2, 2.4.4 and 2.4.5, Boeing may elect to increase the Maximum Takeoff Weight from *pounds up to as much as *pounds. Any such increase in Maximum Takeoff Weight would be an exclusive remedy for this purpose and would be in lieu of all other rights, remedies and claims Customer may have associated with the mission payload guarantees.

5.7		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.

5.8		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.
