Definition
The airspace directly above and around a designated parachute landing area, extending from the surface up to the altitude from which parachutists exit the aircraft. It is the volume of sky used by jumpers from exit point to ground.
Plain English
The block of air above a parachute landing site that skydivers fall through after they leave the aircraft.
Context Anchor
Seen on charts, in notices, and in air traffic communications when parachute operations are active or expected.
Derivation
Jump comes from the ordinary idea of leaping or dropping. Zone comes from a Greek word meaning a belt or marked-off area. Together, the words point to a marked area used for parachute jumps.
Why Pilots Care
Avoiding or coordinating with jump zones prevents traffic conflicts with descending parachutists and ensures safe separation during flight planning and en route operations.
Intuition Check
Do not think of a jump zone as only a small landing spot on the ground. In aviation use, it also means the surrounding area where parachutists may be descending through the air.
Example Sentence 1
ATC advised the pilot to remain clear of the jump zone over the airport while parachute operations were in progress.
Example Sentence 2
ATC issued a traffic advisory noting parachute operations in the jump zone located five miles north of the airport.
