BFO 2 Reference: In all areas of empirical inquiry we encounter general terms of two sorts. First are general terms which refer to universals or types:animaltuberculosissurgical procedurediseaseSecond, are general terms used to refer to groups of entities which instantiate a given universal but do not correspond to the extension of any subuniversal of that universal because there is nothing intrinsic to the entities in question by virtue of which they – and only they – are counted as belonging to the given group. Examples are: animal purchased by the Emperortuberculosis diagnosed on a Wednesdaysurgical procedure performed on a patient from Stockholmperson identified as candidate for clinical trial #2056-555person who is signatory of Form 656-PPVpainting by Leonardo da VinciSuch terms, which represent what are called ‘specializations’ in [81
Entity doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example Werner Ceusters 'portions of reality' include 4 sorts, entities (as BFO construes them), universals, configurations, and relations. It is an open question as to whether entities as construed in BFO will at some point also include these other portions of reality. See, for example, 'How to track absolutely everything' at http://www.referent-tracking.com/_RTU/papers/CeustersICbookRevised.pdf
An entity is anything that exists or has existed or will exist. (axiom label in BFO2 Reference: [001-001])
entity
is utilized to identify, analyze, and troubleshoot issues in aircraft systems, such as oscilloscopes and thermography cameras, which assists pinpointing the root causes of failure and facilitating timely and accurate maintenance; also refers to maintenance tools for verifying the performance and integrity of aircraft components, such as Pitot-Static testers and fuel quantity testers
includes tools like pliers, screwdrivers, wrenches, and hammers, which are versatile and used for most maintenance activities
is used to support the aircraft on the ground, which include the tools used to move the aircraft, like tugs and tow bars, and servicing tools for refueling
activity that supports aircraft maintenance processes
aircraft component that requires maintenance activities
material that should be consumed during aircraft maintenance
maintenance work links covering activities, personnel, technical data, equipments, facilities and other elements involved in aircraft maintenance tasks
refers to electric or pneumatic tools that provide auxiliary power to perform maintenance activities efficiently, such as drills, impact wrenches, grinders, and saws
person who is qualified to perform a specified maintenance process
includes a series of tools for cleaning parts and surfaces, as well as applying corrosion-inhibiting substances
refers to specific tools designed for performing specialized work, which is designed to meet the unique requirements of aircraft maintenance. Some examples include safety devices (used to protect maintenance personnel from potential hazards) and lifting & rigging tools (used to lift, move or position heavy equipment safely)
is used to perform tasks in a manner that ensures the safety of the technician and the aircraft, which involves tools designed to prevent foreign object damage, such as personal protective equipment for the technician
part and component that are operated on during aircraft maintenance
is used to inspect settings and components in the activity of ‘Inspection’, such as flashlights, inspection mirrors, and borescopes. It also refers to maintenance tools used to ensure the accuracy and reliability of measurement devices, such as torque wrenches, pressure gauges, multimeters, and temperature probes
includes tools used to apply sealants to prevent leaks, as well as the equipment used for painting and coating the aircraft to protect it from the elements
