The Alaska CTAF Frequency Grid overlay provides a statewide visual breakdown of Common Traffic Advisory Frequency (CTAF) zones, allowing pilots to instantly identify which frequency to use based on their location. This overlay clearly outlines the boundaries of each CTAF area across uncontrolled airspace, reducing frequency confusion and improving radio communication—especially in remote regions with overlapping or shared-use frequencies. Designed for both enroute and local operations, this tool supports safer self-announced traffic coordination and helps pilots stay compliant with FAA-recommended procedures throughout Alaska.
