28. A) Procedure of controller’s actions when directing aircraft to the alternate aerodrome.
If the aerodrome cannot receive the aircraft due:
blocked runway,
bad runway conditions ( water – 10mm or more, slash – 12mm or more, snow – over 50mm, braking coefficient – less than 0,3, braking action poor),
weather below minima,
low RVR or cloud base,
landing system failure
and the flight crew has made decision to fly to the alternative aerodrome, the controller shall inform the supervisor about diverting the aircraft to an alternative.
The aircraft is cleared to proceed to the alternative if the length and the operational conditions on the alternative aerodrome are applicable for the aircraft and it handles international flights (for the aircraft carrying out an international flight).
If airspace conditions allow to follow direct to the alternative aerodrome, the aircraft shall be cleared to fly to new destination via the shortest route. If airspace conditions do not allow to follow direct to the alternative the aircraft shall be cleared to fly to a new destination and the controller shall instruct the pilot to fly via the cleared route.
Directing the aircraft to the alternative aerodrome the controller shall:
specify the operational conditions, actual and forecast weather conditions at the alternative aerodrome and advise this information to the pilot before the aircraft leaves the zone of responsibility,
inform the anti-aircraft defense forces unit about the flight directed to the aerodrome of changed destination,
inform the adjacent ATC unit about diverting the aircraft to the alternative aerodrome (if the aerodrome is located within its FIR) or inform the aerodrome ATC unit about diverting the aircraft to the alternative aerodrome,
make relevant changes to the flight plan,
transfer the control under the aircraft to the adjacent ATC unit,
obtain the information concerning the aircraft landing on the alternative aerodrome.
b) TCAS. What is it?
A traffic collision avoidance system or traffic alert and collision avoidance system (both abbreviated as TCAS) is an aircraft collision avoidance system designed to reduce the incidence of mid-air collisions between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air traffic control, and warns pilots of the presence of other transponder-equipped aircraft which may present a threat of mid-air collision (MAC). It is a type of airborne collision avoidance system mandated by the International Civil Aviation Organization to be fitted to all aircraft with a maximum take-off mass (MTOM) of over 5700 kg (12,586 lbs) or authorized to carry more than 19 passengers.
Official definition from PANS-ATM (Nov 2007): ACAS / TCAS is an aircraft system based on secondary surveillance radar (SSR) transponder signals which operates independently of ground-based equipment to provide advice to the pilot on potential conflicting aircraft that are equipped with SSR transponders.
In modern glass cockpit aircraft, the TCAS display may be integrated in the Navigation Display (ND); in older glass cockpit aircraft and those with mechanical instrumentation, such an integrated TCAS display may replace the mechanical Vertical Speed Indicator (which indicates the rate with which the aircraft is descending or climbing).
