Definition
A regulatory phrase used in aircraft certification referring to the specific design and performance qualities of an aircraft related to how it produces thrust, how it behaves in the air, and how it touches down. These characteristics — such as engine type, stall behavior, control response, and landing gear configuration — are evaluated to determine whether the aircraft meets airworthiness standards and can be safely operated within its intended category.
Plain English
The qualities of an aircraft that describe how it makes power, how it flies, and how it lands. Regulators look at all three when deciding if the aircraft is safe and what category it fits into.
Context Anchor
Seen in aircraft category, class, certification, and pilot qualification discussions.
Derivation
Characteristic comes from a Greek word meaning a distinguishing mark. That fits this aviation use because these are the marks or features that distinguish one kind of aircraft from another.
Why Pilots Care
These characteristics determine the aircraft's certification category, which sets the limits a pilot must operate within — including allowable maneuvers, weight limits, and approved operations.
Intuition Check
Do not read characteristics here as vague traits or preferences. In this context, it means specific aircraft features that determine how the aircraft is grouped and operated.
Example Sentence 1
The aircraft's certification depended on its characteristics of propulsion, flight, or landing meeting the standards for the utility category.
Example Sentence 2
Changes to the wing design altered the characteristics of propulsion, flight, or landing enough to require new performance charts.
