ASTM WK30921

    Revision of F2245 - 10 Standard Specification for Design and Performance of a Light Sport Airplane

    (What is a Work Item?)

    Active Standard: F2245 - 16c

    Developed by Subcommittee: F37.20 | Committee F37 | Contact Staff Manager


    1. Rationale

    The current standard shows some impracticalities in the definition of the design speeds. This gets directly apparent for aircraft when floats are added, as design speeds increase while the aircraft speed capabilities factually decrease. The reason for this is the specific selection of factors in the formula defining the design speeds. With this starting point, within this WK the design speed definitions shall be reviewed and refined for better suitability.
