Design Freeze. Vehicle shall be disqualified and shall not compete in any subsequent flight attempt if it is modified in any significant way after its first successful qualifying flight attempt.
Design Freeze. Once the Owner has accepted in writing the Design Development (35%) Plans and Specifications, subject to resolution of all design review comments, the design shall be considered “frozen”, and any substantial changes requested thereafter by the Owner shall be at a charge, unless the required changes are due to unplanned A-E modifications subsequent to the 35% Design Documents. The A-E shall obtain, from the Owner, a Design Development approval letter, indicating that the Owner has approved the Design Development submission and other work on previous phases including a list of all Value Engineering Alternatives accepted by the Owner. The revised fee for any subsequent changes shall be determined pursuant to the Comprehensive Agreement.
Design Freeze. Vehicle may not be modified in any significant way after its first successful qualifying Flight Attempt at the CFTC. CAFE officials will monitor this and provide overnight security/surveillance to assure that no tampering or modifications occur. Minor repairs including failed part replacement with identical part may be allowed if pre-approved by CAFE (e.g., a flat tire). Internal or external taping over cabin door seams, vents, windows, baggage outlets, etc. is expressly forbidden. The same propeller must be used for all flight attempts including noise, takeoff distance, minimum flight speed, MPGe and mph attempts. The same fuel type/specification and/or battery pack must be used for all flight attempts including noise, takeoff distance, minimum flight speed, MPG Flight and Speed Flight attempts. No battery cell or battery pack may be replaced once the competition begins. No engine-bay changes/adjustments such as turbocharger boost, prop governor setting, valve timing or ignition timing are allowed once the competition begins.
Design Freeze. Vehicle shall be disqualified and shall not compete in any subsequent Flight Attempt if it is modified in any significant way after its first successful qualifying Flight Attempt at the CFTC. CAFE officials will monitor this and provide overnight security watch to assure that no tampering or modifications occur.
