Descent Below MDA

Question 1

Descent below the straight-in MDA or continuation of the approach below the DA during APVs, may only occur when?

Answer 1

1. Visual reference can be maintained;
2. All elements of meteorological minima are equal to or greater than those published for the aircraft performance category
3. The aircraft is continuously in a position in which a descent to a landing on the intended runway can be made at a normal rate of descent using normal flight manoeuvres that will allow touch down to occur within the touchdown zone of the runway intended for landing

Question 2

During visual circling, descent below the circling MDA May only occur when the pilot:

Answer 2

1. Maintains the aircraft within the prescribed circling area
2. Maintains a visibility along the intended flight path not less than the minimum prescribed on the chart; and
3. Maintains visual contact with the landing runway environment (threshold/approach lighting/other markings idintifiable with the runway)

• BY DAY: descend in any position below MDA to an altitude that maintains obstacle clearance for performance category (400ft)
• BY NIGHT: from a position on the downwind / base or final leg complete a continuous descent from MDA to the THRESHOLD using rates of descent and manoeuvres normal to the aircraft type
