MATS 1 Definitions Flashcards
When is Transfer of Control achieved?
when a flight which is operating in accordance with the co-ordination, has reached the position or level agreed between the transferring and accepting units.
Where does Transfer of Control take place?
1) at an agreed reporting point
2) on an estimate for a FIR boundary
3) At or passing an agreed level; or
4) while the aircraft is climbing or descending to a previously agreed level, provided that the transferring controller has ensured that standard separation will exist between the transferred aircraft and all others for the remainder of the climb or descent.
What phrase should not be used in response to an initial call from an aircraft?
The phrase ‘continue as cleared’ is not to be used in response to an initial call from an aircraft.
Transfer of Communications
Transfer of control must not be confused with transfer of communication.
Transfer of communication is permitted so that instructions, which become effective later, can be issued. It is emphasised that an accepting ATC unit which is in communication with an aircraft not having yet reached the stage of transfer of control shall not alter the clearance without approval of the transferring unit.
what is an Expected Approach Time?
the time at which ATC expects that an arriving aircraft, following a delay, will leave the holding fix to complete its approach for landing. The actual time of leaving the holding fix will depend upon the approach time.
what are EATs based on?
the landing rate, and calculated according to the traffic situation. They are expressed as actual times (not as time intervals)
what are EATs based on?
the landing rate, and calculated according to the traffic situation. They are expressed as actual times (not as time intervals) and revised if the situation changes.
when are EATs passed
they are to be passed to aircraft well in advance, and revised until the aircraft has left the holding facility.
when will the expression ‘delay not determined’ be used?
if for reasons other than weather the extent of the delay is not known. as soon as it is possible for aircraft to recommence approach procedures, EATs are to be issued.
when should ‘delay not determined’ not be used?
when changing runways
if aircraft elect to hold for weather improvement, what should a controller do?
the controller shall inform the first aircraft entering the hold ‘no traffic delay expected’
subsequent aircraft are to be passed ‘delay not determined (number) aircraft holding for weather improvement’
