14 CFR. See Title 14 of the Code of Federal Regulations.

3P. An acronym that represents the three components of the risk management cycle: Perceive, Process, Perform.

Acceptable risk. That part of identified risk that is allowed to persist without further engineering or management action. Making this decision is a difficult yet necessary responsibility for managing activity. This decision is made with full knowledge that it is the user who is exposed to this risk.

Aeronautical decision-making (ADM). A systematic approach to the mental process used by aircraft pilots to consistently determine the best course of action in response to a given set of circumstances.

Automatic decision-making. Quick decision-making based on experience and the expectation of a good outcome.

CARE. An acronym that represents the four risk assessment and mitigation elements: Consequences, Alternatives, Reality, and External pressures.

CAST/ICAO Common Taxonomy Team (CICTT). A group that developed common classifications and definitions for aviation accident and incident reporting.

Checklist. A tool that is used as a human factors aid in aviation safety. It is a systematic and sequential list of all operations that must be performed to accomplish a task properly.

Commercial Aviation Safety Team (CAST). Organization founded in 1997 to bring together various segments of the aviation community with the goal to reduce accidents through a data-driven approach.

Controlled flight into terrain (CFIT). An accident whereby an airworthy aircraft, under pilot control, inadvertently flies into terrain, an obstacle, or water.

CFR. See Title 14 of the Code of Federal Regulations.

Crew resource management (CRM). The application of team management concepts in the flight deck environment. CRM programs evolved to include cabin crews, maintenance personnel, and others. Pilots of small aircraft, as well as crews of larger aircraft, should make effective use of all available resources; human resources, hardware, and information. A current definition includes all groups routinely working with the flight deck crew who are involved in decisions required to operate a flight safely. These groups include, but are not limited to: pilots, dispatchers, cabin crewmembers, maintenance personnel, and air traffic controllers. CRM is one way of addressing the challenge of optimizing the human/machine interface and accompanying interpersonal activities.

Currency. Meeting all established requirements.

Electronic flight bag (EFB). A portable or integrated device that allows the pilot to carry all necessary aeronautical and performance data, weight and balance, and aircraft checklists in digital form and may allow remote manipulation of the avionics through wireless radio connections.

Emergency. An urgent condition or distress that requires immediate attention.

Error. Deviations from intended or expected actions that are caused by the flight crew that cause confusion, increase workload, absorb attention, reduce safety margins, increase risk, and may lead to undesired aircraft states.
