What does ATC expect when cleared for the RNAV (GPS) RWY 28 approach over APE VORTAC?

When ATC clears a pilot for the RNAV (GPS) RWY 28 approach over APE VORTAC, it indicates that the pilot is expected to navigate directly to a specific fix along the approach path, which in this case is at FAIRF. Proceeding straight in means that the aircraft will align with the runway once the necessary conditions, such as altitude and position, are met.

By instructing the pilot to descend after reaching FAIRF, ATC ensures a controlled and safe descent profile that adheres to the procedure for the RNAV approach, allowing for a stable approach to the runway. This is a standard expectation for aircraft approaching an airport when the clearance has been given, as it facilitates both the flow of air traffic and pilot compliance with the specific approach procedures.
