CAT II/III OPERATIONS AT AERODROMES
PROCEDURES FOR CONTROL OF TRAFFIC WHEN ILS CATEGORY II APPROACH IS IN USE AT KIA
During periods of reduced visibility, it is necessary to introduce procedures to ensure that high levels of safety are maintained in the aircraft movement and that runway operations are properly safeguarded.
Meteorological Office is responsible of determining whether there is low visibility at Kigali international Airport. RVR is used to determine both horizontal and vertical visibility of the runway.
After determining that there is a low visibility, the MET Officer on duty will immediately notify aerodrome controller at KIA.
Upon receiving such information, the aerodrome control tower will inform the area control unit when procedures for ILS CAT II and low visibility operations will be applied and also when such procedures are no longer in force.
In addition to the actions above by ATC after he/she is informed of low visibility by Met office, the aerodrome Controller on duty shall also inform the following of the activation of LVPs;
-
Airside Coordinator / Operations Officer on duty;
-
The Marshaller on duty and;
-
RFFS shift leader on duty.
ILS category II will be in use when RVR is below 800m but not less than 300m, decision height lower than 60m (200ft), but not lower than 30m (100ft).
RVR value for takeoff will be 500m
Aerodrome controller will switch on CAT II aeronautical ground lights and ensure continuous monitoring of air field ground lights display;
Aerodrome controller will report any relevant equipment failure and degradation, without delay, to the flight crew concerned, the area control unit, and aerodrome operator.
Procedures for the control of traffic on the manoeuvring area;
The runway-holding positions to be used;
|
A, B and C |
The minimum distance between an arriving and a departing aircraft to ensure protection of the sensitive and critical areas;
|
Only one aircraft movement at time during departure or arrival will be allowed. |
Ensuring that aircraft and vehicles have vacated the runway
|
Aircraft and vehicles will maintain two-way communication with aerodrome controller and report vacating the runway. |
Separation of aircraft and vehicles;
|
Withdraw all vehicles and personnel involved in construction, maintenance and other non-essential activities. |
Spacing between successive approaching aircraft;
|
One aircraft will be cleared for approach and the rest will be holding in their respective holding patterns. |
Action(s) to be taken in the event low visibility operations need to be discontinued, e.g. due to equipment failures; and
|
ILS CAT II will be suspended and revert to ILS CAT I |
