ATC clears a pilot for 'timed approaches' to an airport without radar service, with multiple aircraft holding at the same fix awaiting sequential approach clearances. What condition must exist for ATC to authorize timed approaches?
- AThe airport must have an operating control tower with radar coverage
- BAll aircraft in the sequence must be the same approach category
- CThe reported ceiling and visibility must be at or above the highest circling minimums for the category of aircraft
- DAt least one precision approach must be available at the airport
Show answer & explanationAnswer & explanation
Correct answer: C. The reported ceiling and visibility must be at or above the highest circling minimums for the category of aircraft
Timed approaches from a holding fix require that the reported ceiling and visibility be equal to or greater than the highest circling minimums for the aircraft category in the approach sequence, ensuring aircraft can maintain appropriate spacing without radar separation.
Why the other options are wrong
- A. Timed approaches are specifically used when radar service is not available or has been discontinued
- B. Aircraft of different categories can be sequenced as long as minimums are met
- D. A precision approach is not a prerequisite for timed approaches
Timed Approaches from a Holding Fix
A non-radar procedure allowing ATC to sequence aircraft for approaches at set time intervals when ceiling and visibility meet or exceed the highest circling minimums for the aircraft category involved.
- Requires reported ceiling/visibility at or above highest circling minimums
- Used when radar is unavailable or out of service
- Aircraft depart the holding fix at specified time intervals toward the airport
Memory trick: No radar? Time it, but only if the weather's clear enough to circle.
