Appropriate revision of the formula will be made to accomplish this result. 5.4 Should the above escalation provisions become null and void by action of the US Government, the V2533-A5 Reference Price will be adjusted to reflect increases in the cost of labor, material and fuel which have occurred from the period represented by the applicable V2533-A5 Reference Price indexes to the fourth month prior to the scheduled delivery of the A321 Additional Aircraft. 5.5 The revised V2533-A5 Reference Price at delivery of the A321 Additional Aircraft in no event will be less than the V2533-A5 Reference Price defined in Paragraph 1 of this Exhibit E.

The Performance Engineering Program may be used by the Buyer under the license conditions set forth in Appendix A to this Exhibit H. The Low Speed Performance programs consist of the Take-off and Landing Chart computation program (TLC) which permits the computation of: - regulatory take-off and landing performance, - noncertified take-off performance accounting for runway data and weather, together with the Tabulation and Interpolation program (TAB), issued with the AFM, which permits the reading, editing and interpolation of the tables listed in the AFM. The High Speed Performance programs are the In Flight Performance computation program (IFP) which permits computation of Aircraft performance for each flight phase and the Aircraft Performance Monitoring program (APM) which permits analysis of Aircraft cruise performance from data recorded during stabilized flight periods. ExhH-6 70 4.6 Performance Program Manual (PPM) The PPM is the users' guide for the Performance Engineering Program (PEP). 4.7 Noise Level Calculation Program (NLCP) The NLCP is a software program which includes all the performance and noise data for each A320 family aircraft/engine combination. When combined with the OCTOPER software, it provides take-off and approach noise computations. 4.8 OCTOPER Operational Flight path computation to optimize gross flight path. 4.9 Weight and Balance Manual (WBM) and Weight and Balance Manual Supplements--C The corresponding supplements: -Delivery Weighing Report, -Equipment List, will be delivered with each Aircraft or Additional Firm Aircraft, as applicable. 5.
