Survivability enhanced by armor allocated to protect pilot / crewspaces and / or critical operating systems.
Incorporates two or more engines, enhancing survivability and / or performance.
Utilizes two or more types of propulsion systems to achieve desired performance / flight actions.
Mainplanes, or leading edges, features swept-back lines for enhanced high-speed performance and handling.
Inherent ability of airframe to take considerable damage.
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.
PILOT / CREW EJECTION SYSTEM
Assisted process of allowing its pilot and / or crew to eject in the event of an airborne emergency.
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.
