A cursory analysis of VTOL carrier operations and aircraft characteristics was accomplished to provide a first-order indication of some of the requirements for successful sea-based VTOL aircraft operations. Day VFR carrier takeoffs and landing procedures need not differ significantly from current operations. Night and adverse weather capabilities of VTOL aircraft will be as good as, or better than those of conventional jet aircraft. Carrier deck motions in sea state 6 and aerodynamic wakes in a 20-knot wind over the deck do not appear to present significant problems. Further investigation of a wider spectrum of conditions, including a flight simulator program, is recommended. Aircraft controls are expected to have a critical maneuver range at about half the aerodynamic stall speed. Carrier operations may well take place in this critical speed regime due to a combination of carrier speed and ambient wind velocities. Pilot training requirements depend on the particular airplane configuration. Current jet VTOL aircraft have not presented training problems. The hover control power requirements are believed to be inversely proportional to the square root of the gross weight, which results in a constant control thrust/airplane weight ratio over a large range of airplane weights. Automatic attitude stabilization materially improves landing accuracy and reduces approach time. (Author)
