Timed approaches using either nonradar procedures or radar vectors to the final approach course may be used at airports served by a tower if the following conditions are met:
- These procedures require NAVAIDs and standard/special instrument approach procedures or adequate radar coverage which permit an aircraft to:
- 1. Hold at a fix located on the approach course or to be radar vectored to the final approach course for a straight-in approach in accordance with the minima specified in para 6-7-5, Interval Minima.
- 2. Proceed in the direction of the airport along the approach course crossing the holding/approach fix at a specified altitude if required.
- 3. Continue descent for an approach to destination airport.
- Direct communication is maintained with the aircraft until the pilot is instructed to contact the tower.
- If more than one missed approach procedure is available, none require course reversal.
- If only one missed approach procedure is available, the following conditions are met:
- Course reversal is not required.
- Reported ceiling and visibility are equal to or greater than the highest prescribed circling mini- mums for the instrument approach procedure in use.
NOTE: Determination of whether or not an existing ceiling meets minima is accomplished by comparing MDA (MSL) with ceiling (AGL) plus the airport elevation.
