When operating on unpublished routes, issue the approach clearance only after the aircraft is

The key concept is that, with unpublished routes, there must be a defined, published path to join the approach before you issue the approach clearance. Being established on a segment of a published route or instrument approach gives the pilot a clear, navigable transition into the approach and allows ATC to ensure proper separation and coordination. If you wait until the aircraft is only on a heading that will intercept the initial segment, or on the final approach course, you’d be asking the pilot to join an approach from an undefined path or from a late stage of the procedure. An altitude assignment alone doesn’t provide a published path to the approach, so it doesn’t satisfy the requirement for a published transition. Establishment on a published segment ensures the approach can be entered safely from a known path, after which the approach clearance can be given.
