MULTI-ENGINE
Incorporates two or more engines, enhancing survivability and / or performance.
PUSHER-PROP
Design incorporates rear-facing pusher-prop arrangement, a contrast to the more conventional puller-prop layout.
WINGLETS
Mainplanes capped with winglets, providing improved fuel efficiency and enhanced handling.
CANARDS
Small foreplanes ahead of the mainplanes reduce wing-loading and / or enhance maneuverability during high angle-of-attack or stall actions.
HIGH-SPEED PERFORMANCE
Can accelerate to higher speeds than average aircraft of its time.
HIGH-ALTITUDE PERFORMANCE
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.
SUPER PERFORMANCE
Design covers the three all-important performance categories of speed, altitude, and range.
MARITIME OPERATION
Ability to operate over ocean in addition to surviving the special rigors of the maritime environment.
CREWSPACE PRESSURIZATION
Supports pressurization required at higher operating altitudes for crew survival.
ENCLOSED CREWSPACE(S)
Features partially- or wholly-enclosed crew workspaces.
RETRACTABLE UNDERCARRIAGE
Features retracting / retractable undercarriage to preserve aerodynamic efficiency.
