Definition
The title of an instrument approach procedure chart indicating that the approach to Runway 15 may be flown using either VOR (VHF Omnidirectional Range) ground-based navigation or GPS (Global Positioning System) satellite-based navigation as the primary means of lateral guidance. A single chart serves both navigation methods, and the pilot selects which equipment to use based on what is installed, operational, and authorized in the aircraft.
Plain English
This is the name of an approach chart for landing on Runway 15. The pilot can fly the approach using either a VOR receiver or a GPS receiver — whichever the aircraft is equipped with and approved to use.
Context Anchor
Seen at the top of an instrument approach chart, where the procedure name tells the pilot what navigation equipment the approach uses and which runway it serves.
Derivation
VOR comes from “VHF Omnidirectional Range,” a radio navigation system. GPS comes from “Global Positioning System,” a satellite navigation system. RWY is the chart abbreviation for “runway.” The number 15 means the runway is aligned roughly toward 150 degrees magnetic.
Why Pilots Care
It confirms which navigation equipment the pilot is allowed to use for that specific runway, directly affecting flight planning and approach clearance acceptance.
Intuition Check
“Or” matters here: it means the procedure may be flown by either authorized navigation method. It does not mean the pilot must use both at the same time.
Example Sentence 1
Before starting the descent, the pilot briefed the VOR or GPS RWY 15 approach and selected GPS as the primary navigation source.
Example Sentence 2
After reviewing the VOR or GPS RWY 15 plate, the crew noted the minimum descent altitude and the missed approach instructions.
