Circling Approaches

Question 1

What are the rules for CIRCLING APPROACHES and descent below MDA?

Terminal AU-24 (4.14)

Answer 1

1 The aircraft remains WITHIN the
CIRCLING AREA and

2 Maintains a VISIBILITY along the
intended flight path, NOT LESS
THAN the minimum specified for
circling

3 Maintains VISUAL CONTACT with
the landing runway environment, and
either

4    In DAYLIGHT only, maintains visual 
      contact with obstacles along the 
      flight path and a OBSTACLE 
      CLEARANCE not less than the 
      minimum for the aircraft category
      (CAT A/B 300ft) until the aircraft is 
      aligned with the landing runway

5    By DAY or NIGHT, at not less than 
       the MDA, intercepts a position on
      the DOWNWIND, BASE, or FINAL leg
      of the landing pattern, and can 
      make a descent and landing 
      within the normal rates of the 
      aircraft, and maintaining obstacle
      clearance along the flight path
      not less than the minimum for the
      aircraft performance category
      until the aircraft is aligned with 
      the centreline.
