Incorporates two or more engines, enhancing survivability and / or performance.
Design incorporates rear-facing pusher-prop arrangement, a contrast to the more conventional puller-prop layout.
Mainplanes capped with winglets, providing improved fuel efficiency and enhanced handling.
Small foreplanes ahead of the mainplanes reduce wing-loading and / or enhance maneuverability during high angle-of-attack or stall actions.
Can accelerate to higher speeds than average aircraft of its time.
Can reach and operate at higher altitudes than average aircraft of its time.
EXTENDED RANGE PERFORMANCE
Capability to travel considerable distances through onboard fuel stores.
Design covers the three all-important performance categories of speed, altitude, and range.
Ability to operate over ocean in addition to surviving the special rigors of the maritime environment.
Supports pressurization required at higher operating altitudes for crew survival.
Features partially- or wholly-enclosed crew workspaces.
Features retracting / retractable undercarriage to preserve aerodynamic efficiency.
