Definition
The categories of airworthiness standards under which an airplane is certified by the FAA, defining the design, performance, and operational requirements the airplane must meet. For multiengine airplanes, the relevant categories typically include normal, utility, acrobatic, commuter, and transport, each with its own structural, performance, and equipment standards under Title 14 of the Code of Federal Regulations.
Plain English
The category an airplane was built and approved to meet. Different categories have different rules for how the airplane must be designed, how strong it must be, and what it is allowed to do.
Context Anchor
Seen in multiengine airplane performance discussions, especially when comparing what different airplanes are required to demonstrate during certification.
Derivation
From 'certify,' from Latin certus ('sure, settled') plus facere ('to make') — literally 'to make sure of.' A certification level is the standard the FAA has 'made sure of' for that airplane's design and use.
Why Pilots Care
Determines whether the airplane can safely perform certain maneuvers or carry specific loads during training and normal operations.
Intuition Check
Do not read certification levels as pilot certificate levels, such as private or commercial. Here it means the approval standards for the airplane design, not the pilot’s qualifications.
Example Sentence 1
Before training in a new multiengine airplane, the instructor reviewed its certification level so the student understood which maneuvers were approved.
Example Sentence 2
The multiengine airplane's certification level limited it to normal category operations, so spins were not permitted.
