2   Arriving flights

2.1  IFR flights entering and landing within a terminal control area will be cleared to a specified holding point and instructed to contact a designated Approach Control at a specified time, level or/and position. The terms of those clearance shall be adhered to until further instructions are received from the Approach Control. If the flights reach at the clearance limit before further instructions received, holding procedure shall be carried out at the level last authorized.
2.2  Due to the limited airspace available, it is important that the approaches to the patterns and the holding procedures be carried out as precisely as possible. Pilots are strongly requested to inform ATC if for any reason the approach and/or holding cannot be performed as required.
2.3  Manoeuvering(Circling) Areas are listed in Diagram 1 and Tables 1 and 2-1, 2-2 as follows:

2.3.1  The approaches using expanded circling approach areas can be identified by the presence of the

symbol on the circling line of minima.
2.4  Circling minima

In some busy terminal areas, ATC may not allow circling and circling minimums will not be published. Published circling minimums provide obstacle clearance when pilots remain within the appropriate area of protection. Pilots should remain at or above the circling altitude until the aircraft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal maneuvers. Circling may require maneuvers at low altitude, at low airspeed, and in marginal weather conditions. Pilots must use sound judgment, have an indepth knowledge of their capabilities, and fully understand the aircraft performance to determine the exact circling maneuver since weather, unique airport design, and the aircraft position, altitude, and airspeed must all be considered. The following basic rules apply:

2.4.1  Maneuver the shortest path to the base or downwind leg, as appropriate, considering existing weather conditions. There is no restriction from passing over the airport or other runways.
2.4.2  It should be recognized that circling maneuvers may be made while VFR or other flying is in progress at the airport. Standard left turns or specific instruction from the controller for maneuvering must be considered when circling to land.

3   Departing flights

3.1  IFR flights departing from controlled aerodromes will receive initial ATC clearances from the local aerodrome control tower. The clearance limits will normally be the aerodrome of destination.
3.2  Detailed instructions with regard to routes, turns, etc. will be issued before or after take-off.

4   Other relevant information and procedures

4.1  Minimums are specified for various aircraft approach categories based upon a value 1.3 times the stalling speed of the aircraft in the landing configuration at maximum certified gross landing weight. Aircraft Approach Categories are listed in Table 3 as follows:

<Table 3> Aircraft Approach Category

Aircraft Approach Category

Speed(IAS)

A

Speed less than 91knots

B

Speed 91 knots or more but less then 121 knots

C

Speed 121 knots or more but less then 141 knots

D

Speed 141 knots or more but less then 166 knots

E

Speed 166 knots or more

4.2  An aircraft shall fit in only one aircraft approach category. If it is necessary to maneuver at speeds in excess of the upper limit of a speed range for a category, the minimums for the next higher category should be used. If it is necessary, while circling-to-land, to maneuver at speeds in excess of the upper limit of the speed range for each category, due to the possibility of extending the circling maneuver beyond the area for which obstruction clearance is provided, the circling minimum for the next higher approach category should be used. For example, an aircraft which falls in Category C, but is circling to land at a speed of 141 knots or higher should use the approach category "D" minimum when circling to land.
