Question
ADVANCED CLASS 2025
- Are there restrictions on position of the rotors during conventional takeoff?
Answer
Advanced Class Conventional Takeoff shall employ aerodynamic lift generation from fixed wing surfaces during horizontal ground roll. Ground roll distance will be an outcome of the design but should be nonzero. Vertical takeoff from the runway is not 'conventional'. A hybrid approach with a propulsion device generating predominately vertical thrust (lift) shall not be considered Conventional Takeoff. Given various propulsion solutions, a thrust line of up to 10 degrees from horizontal (runway/earth axis) is considered acceptable during conventional takeoff for Advanced Class. Any propulsion device oriented greater than 10 degrees from horizontal shall not be active during Conventional Takeoff through liftoff. Similarly, during Return to Base (Conventional Landing), Advanced Class aircraft shall not utilize propulsion systems generating vertical thrust (propulsion devices with thrust lines greater than 10 degrees from horizontal/runway axis).

VTOL capability for payload delivery/capture at the DLZ is not prohibited. Aircraft must not touchdown outside designated landing zone (payload DLZ) and main runway.
