Special Conditions: Dassault Aviation Model Falcon 6X Airplane; Hydrophobic Windshield Coatings in Lieu of Windshield Wipers

When an aircraft design includes a novel feature not addressed by the existing 14 CFR airworthiness standards, the FAA imposes Special Conditions — additional requirements specific to that design. They're project-specific, not type-applicable.
