Definition
A small auxiliary parachute used to pull a larger main parachute out of its pack and into the airstream. The pilot chute deploys first, catches the air, and uses the resulting drag to extract and open the main canopy.
Plain English
A little parachute whose only job is to pull the big parachute out so it can open.
Context Anchor
Seen in discussions of emergency parachutes, skydiving parachute systems, and parachute packing or inspection.
Derivation
Called a 'pilot' chute because it pilots — that is, leads or guides — the main parachute out of its container, the same way a pilot boat leads a larger ship into harbour.
Why Pilots Care
Reliable pilot-chute deployment is essential for successful emergency parachute opening in bailout or aircraft recovery situations.
Grounding Statement
Picture a small parachute popping into the airflow first and using that pull to drag the larger parachute out behind it.
Intuition Check
Do not read “pilot chute” as a chute for the aircraft pilot. Here, “pilot” means the chute that goes first and starts the parachute-opening sequence.
Example Sentence 1
When the ripcord was pulled, the pilot chute popped clear of the pack and dragged the main canopy into the airstream.
Example Sentence 2
In the Cirrus ballistic system, the pilot chute inflates first to begin the recovery sequence.
