Profile

Mr. Thomas has over 38 years of technical expertise in air vehicle flight mechanics, with extensive specialization in stability and control (S&C), flying qualities (FQ), and flight controls, with significant experience in internal aerodynamics, external aerodynamics, and flight performance. He was intimately involved in every release of MIL-STD-1797, Flying Qualities of Piloted Aircraft, as well as writing the flying qualities specifications for multiple United States Air Force (USAF) aircraft (F-22, B-21, F-15SA, B-52J). He excels at uncovering technical problems and shortcomings and formulating highly innovative, workable solutions. Mr. Thomas received the “Civilian of the Year” award at every stage of career.

Significant Career Accomplishments

  • Tri-Service lead for MIL-HDBK-516D Section 6 (Flight Technology) update/rewrite.

  • Tri-Service lead for MIL-STD-1797C, Flying Qualities of Piloted Aircraft update.

  • Orchestrated MIL-HDBK-516, Airworthiness Certification Criteria, Flight Technology (Section 6) airworthiness assessments on hundreds of air vehicle modifications and dozens of new-build air vehicles.

  • Wrote the Flying Qualities Specifications for multiple USAF aircraft (e.g., F-22, B-21, F-15SA, B-52J)

  • Provided technical accident investigation support to F-22, A-29, U-2, RC-16, C-17 Safety Investigation Boards (SIB). Identified causal factors and recommendations, all of which were approved.

  • Played critical roles in major programs such as F-15SA, F-16 Automatic Ground Collision Avoidance System (AGCAS), Hypersonic Air-Breathing Weapon Concept (HAWC), KC-X, B-1B, AC-130J, C-5M, and many others, uncovering flight systems deficiencies, finding solutions resulting in redesigns, and      driving policy and technical consensus across government and industry stakeholders.

  • Led flight mechanics technical review, uncovering safety-critical deficiencies leading to cancellation of B-1B conversion of analog-to-digital flight control system.

  • Made unprecedented impacts on F-35 Joint Strike Fighter (JSF) program as the only ASC/EN representative championing incorporation of USAF processes on the Flight Clearance Working Group (FCWG), United States Acceptance Working Group (USAWG), International Acceptance Working Group (IAWG), and Certification Working Group (CWG).

  • USAF lead for developing and coordinating establishment of internationally accepted JSF Policy Directive 39 (PD-39), Flight Clearance Procedure, with major impact on program success.

  • Received the Engineering Directorate’s “Civilian Engineer of the Year" award at every stage of career.
