Did the FAA get rid of airborne VOR checkpoints in the 2026 Chart Supplements?

The 2026 Chart Supplements no longer display the Gnd/AB-ALT columns that previously identified airborne VOR checkpoints, with all currently listed checkpoints appearing to be ground-based facilities. The current AIM still references airborne checkpoints, specifies ±6° tolerances, and states their locations are published in the Chart Supplement, creating a discrepancy between the guidance and available publications. This raises uncertainty about whether the FAA discontinued airborne VOR checkpoints without updating corresponding regulations.
