Definition
A pressurized, twin-engine, six-seat piston airplane manufactured by Beechcraft as part of the Baron family of light general aviation aircraft. The 58P variant features a pressurized cabin, retractable landing gear, and two turbocharged piston engines, allowing operation at higher altitudes than unpressurized piston twins.
Plain English
A small twin-engine private airplane built by Beechcraft, with a sealed cabin that lets it fly comfortably at high altitudes where the outside air is too thin to breathe normally.
Context Anchor
Seen in FAA training material when an example refers to a particular aircraft type, often to give context for performance, pilot workload, or decision-making.
Derivation
Beech refers to Beech Aircraft Corporation (founded 1932 by Walter Beech). The 58 is the model number in the Baron series. The P stands for Pressurized. Baron is the family name Beechcraft chose for this line of twin-engine aircraft, following their tradition of naming models after titles of nobility (Bonanza, Baron, Duke, King Air).
Why Pilots Care
The 58P is often referenced when discussing aeronautical decision-making because it is a fast, complex, pressurized twin that exceeds the capability of many low-time pilots. Matching pilot skill to aircraft capability is a core safety concept.
Grounding Statement
Picture a small business-style propeller airplane with an engine on each wing and a cabin built for higher-altitude trips.
Intuition Check
Do not read “Baron” as a title or general description here. “Beech 58P Baron” names one specific aircraft model.
Example Sentence 1
The accident report noted that the pilot, with limited multi-engine experience, was flying a Beech 58P Baron in conditions that demanded a higher level of proficiency.
Example Sentence 2
Transition training covers the systems unique to the Beech 58P Baron.
