PROCEDURES FOR RADAR APPROACHES

(a)During the period that an air traffic controller is engaged in giving surveillance radar approaches, he or she should not be responsible for any duties other than those directly connected with such approaches.

(b)Air traffic controllers conducting radar approaches should be provided with information regarding the OCAs/OCHs established for the types of approach to be conducted.

(c)Prior to commencement of a radar approach, the air traffic controller should inform the aircraft of the:

(1)runway to be used;

(2)applicable OCA/OCH;

(3)angle of the nominal glide path and the approximate rate of descent to be maintained; and

(4)procedure to be followed in the event of radio communication failure unless the procedure has been published in AIPs.

(d)When a radar approach cannot be continued due to any circumstance, the aircraft should be immediately informed that a radar approach or continuation thereof is not possible. The approach should be continued if this is possible using non-radar facilities or if the pilot reports that the approach can be completed visually; otherwise, an alternative clearance should be given.

(e)Aircraft making a radar approach should be reminded, when on final approach, to check that the wheels are down and locked.

(f)Unless otherwise prescribed by the air traffic services provider, the air traffic controller conducting the approach should notify the aerodrome air traffic controller or, when applicable, the procedural air traffic controller when an aircraft making a radar approach is approximately 15 km (8 NM) from touchdown. If landing clearance is not received at this time, a subsequent notification should be made at approximately 8 km (4 NM) from touchdown and landing clearance requested.

(g)Clearance to land or any alternative clearance received from the aerodrome air traffic controller or, when applicable, the procedural air traffic controller should normally be passed on to the aircraft before it reaches a distance of 4 km (2 NM) from touchdown.

(h)An aircraft making a radar approach should:

(1)be directed to execute a missed approach in the following circumstances:

(i)when the aircraft appears to be dangerously positioned on final approach; or

(ii)for reasons involving traffic conflictions; or

(iii)if no clearance to land has been received from the procedural air traffic controller by the time the aircraft reaches a distance of 4 km (2 NM) from touchdown or such other distance as has been agreed with the aerodrome control tower; or

(iv)on instructions by the aerodrome air traffic controller; or

(2)be advised to consider executing a missed approach in the following circumstances:

(i)when the aircraft reaches a position from which it appears that a successful approach cannot be completed; or

(ii)if the aircraft is not visible on the situation display for any significant interval during the last 4 km (2 NM) of the approach; or

(iii)if the position or identification of the aircraft is in doubt during any portion of the final approach. In all such cases, the reason for the instruction or the advice should be given to the pilot.

(i)Unless otherwise required by exceptional circumstances, radar instructions concerning a missed approach should be in accordance with the prescribed missed approach procedure and should include the level to which the aircraft is to climb and heading instructions to keep the aircraft within the missed approach area during the missed approach procedure.
