Definition
A standard instrument approach procedure designed exclusively for helicopters that uses GPS as the primary navigation source. These procedures are titled with the prefix 'COPTER' and are restricted to helicopter use only, taking advantage of the helicopter's ability to fly slower approach speeds and steeper descent angles than fixed-wing aircraft.
Plain English
A GPS-based instrument approach made just for helicopters. Airplanes are not allowed to use it. Because helicopters can fly slower and descend more steeply, these approaches can be built tighter and closer to obstacles than airplane approaches.
Context Anchor
Seen on helicopter instrument approach charts and in discussions of helicopter-only approaches to an airport or heliport.
Derivation
“GPS” means Global Positioning System. “Copter” is a shortened form of “helicopter”; on an approach title, it signals that the procedure is built for helicopter operations, not that the word is being used casually.
Why Pilots Care
Enables safe, lower-minimum GPS approaches tailored to helicopter capabilities where standard fixed-wing procedures would be unsuitable.
Intuition Check
Do not read “GPS Copter Procedure” as “any GPS approach a helicopter can fly.” It means a published procedure specifically designed and identified for helicopter use.
Example Sentence 1
The crew briefed the COPTER GPS approach into the hospital's airport, noting the lower minimums available to them as a helicopter.
Example Sentence 2
GPS Copter Procedures allow helicopters to reach the runway with vertical guidance matched to their descent performance.
