What is the correct statement regarding PAR approaches?

The statement regarding PAR (Precision Approach Radar) approaches that is correct is that a missed approach is initiated at Decision Height (DH) without visual reference. This is an important aspect of precision approaches, as it underscores the requirement for pilots to follow specific protocols when they do not have visual contact with the runway at the designated decision point.

In a PAR approach, the Decision Height is a critical altitude where the pilot must make a decision to land or execute a missed approach, based on visual reference. If the pilot does not have sufficient visual reference at or before reaching this altitude, they are required to initiate a missed approach procedure. This ensures safety and compliance with air traffic control directives.

In contrast, the other statements do not accurately reflect standard procedures associated with PAR approaches. First visual contact allowing descent to land pertains more to other types of approaches and does not apply under the strict criteria for a PAR. Continuous descent at Minimum Descent Altitude (MDA) is not permitted for precision approaches, where the focus is on maintaining specific altitude restrictions until adequate visual reference is achieved. Lastly, not all passed fixes are cleared to descend; rather, clearances for descent are typically based on specific approach procedures and cannot be generalized in this manner.
