"Why are there five-letter codes on the sectional under some VFR checkpoints?" — Andrew S.
“These are five letter GPS identifiers of VFR checkpoints. This allows a pilot to enter the checkpoint in the GPS for navigation and awareness.
By entering the checkpoint in the GPS, it may assist a pilot in identifying VFR checkpoints or visual reporting points where the associated landmark is difficult to pick up visually.
They can be used for avoidance of specific airspace; e.g., Class B, SUA, etc. It is important to remember though that the charted waypoints do not define the airspace boundaries. They may also be used to support VFR flyway routes with entry and exit points, and, when necessary, intermediate waypoints.
The five-letter identifiers are not designed to be pronounceable or used in ATC communications. A pilot should refer to the name of the geographical point instead.”
Have you ever used VFR checkpoint identifiers in your GPS?
