So What Charts
Mission Envelope CaptureMore %envelope expansion possible on manned systems due to age of SOA baselines compared to SOA UAVs
Solar-Regenerative for endurance above ~60 hours; but limited in Solar latitude, altitude, and seasonal operations
New UAV platforms (eg. tandem fuselage) or qualified operations (eg. mid-air refueling, rotations with data-link x-fer, etc.)
Endurance Envelope Expansion(based on modified Breguet formulation)
