Definition
An FAA classification term for airlines that operate large passenger aircraft and move significant volumes of passengers and cargo, typically used in traffic management and airspace planning contexts.
Plain English
Airlines that fly big aircraft carrying lots of people. The label is used by the FAA when planning and managing air traffic flow.
Context Anchor
Seen in FAA acronym and NOTAM contraction lists, and potentially in airport or airspace notices where information applies especially to large commercial operators.
Derivation
From 'high' (large in degree) and 'capacity' (the amount that can be carried). 'Carrier' in aviation refers to a commercial airline that carries passengers or freight. Together: airlines with the capacity to carry large numbers of people.
Why Pilots Care
Knowing the term helps pilots understand references to major airlines in FAA rules and operational notices.
Intuition Check
Do not read “carrier” as an aircraft carrier ship. Here it means a commercial operator that carries passengers or cargo by aircraft.
Example Sentence 1
Flow control measures during the storm gave priority sequencing to HCAP operators arriving at the hub.
Example Sentence 2
NOTAMs sometimes mention HCAP activity at busy hub airports.
