Proposal for Revisions to the Manual of Criteria for the Qualification of Flight Simulators

1. Proposal for Revisions to the Manual of Criteria for the Qualification of Flight Simulators Kendall W. Neville Associate Technical Fellow - Flight Simulation Aerodynamics Engineering The Boeing Company

2. Summary • Background • Situation • Summary of proposal • Conclusion

3. Background • In January 1992 the draft “International Standards for the Qualification of Flight Simulators” was adopted by the Royal Aeronautical Society • This document was the culmination of a two-year effort by an International Working Group consisting of: • Aviation authorities • Simulator operators • Simulator manufacturers • Data providers including aircraft manufacturers

4. Background (cont’d) • Simulator qualification requirements from major national aviation authorities were consolidated • Additional requirements were defined for Computer Controlled Airplanes and those with reversible control systems • While all requirements were considered, primary focus was Appendix B, Flight SimulatorValidation Tests • Goal: results of the validation tests would be submitted by the applicant to the appropriate authority in an “International Qualification Test Guide” (IQTG)

5. Background (cont’d) • In 1995, the International Standards were published by ICAO as the “Manual of Criteria for the Qualification of Flight Simulators” • Since then, the standards for validation tests have been included in: • JAR-STD1A, “Aeroplane Flight Simulators” • IATA document, “Flight Simulator Design & Data Requirements” • The FAA has not yet formally published the International Standards: however, today’s standards are based largely on the content of AC120-40B

6. Situation • The International Standards are internationally accepted as the foundation for flight simulator qualification. However, they have not been revised since 1992: • Wording and format often are inconsistent • Many tests are unclear as to intent, purpose and method • test results are subject to wide interpretation: • time is wasted discussing how to conduct the tests and interpret the data • during evaluation, authorities sometimes make a new interpretation of a test which was accepted for earlier simulations

7. Summary of Proposal • The proposed changes which we will present are based on: • Boeing experience with • flight-test planning and results • data queries and other feedback from authorities, simulator manufacturers and operators • comments from Airbus

8. Summary of Proposal (cont’d) • Emphasis of the proposal is on the Table of Validation Tests • The proposed changes would ensure that the description of each test is clear, yet retains a reasonable degree of flexibility • An important objective is to add substantial value and usefulness to the Standards without adding unnecessary cost for the industry

9. Summary of Proposal (cont’d) • For some tests, guidance from the Working Group is requested to help decide the best way to improve the test description • Supporting data will be provided where appropriate • Bob Curnutt will highlight those tests for which the most substantive changes are proposed and where the WG should focus attention

10. Summary of Proposal (cont’d) • Proposal to revise the Flight Simulator Validation Tests: • The ICAO Manual now contains 62 performance and handling qualities tests (not including wind shear and envelope protection tests) • Of these, modifications are proposed for 48tests • The number of tests in this category would increase to 69 (mostly because existing tests would be divided into two or more separate tests)

11. Example of Proposed Revised Test

12. Summary of Proposal (cont’d) • Other proposed changes to the Manual include: • Revised wording in Appendix A to consolidate requirements for the aerodynamic model • Revised sequence of paragraphs in Appendix A • Revised Section 3.2, Appendix B, “Ground Effects” • Numerous minor improvements to text and format

13. Conclusion • Boeing is pleased to once again contribute to upgrading the International Standards for flight simulator data • We believe that these proposals will substantially improve the standards for qualification of flight simulators - for the benefit of the industry - without incurring additional cost • Thanks for listening!
