Separation Standards Flashcards
According to MATS 1, what are the circumstances when separation may be deemed to exist between aircraft under Radar Control and unidentified known traffic?
Separation may be deemed to exist between aircraft under Radar Control and unidentified known traffic in the following circumstances:
1) When authorised procedures are in operation whereby the known traffic is under the control of another controller, who is utilising an ATS surveillance system, and separation can be maintained by direct co-ordination, or
2) When authorised procedures are in operation whereby track or vertical separation is deemed to exist
According to MATS Pt 1, between which flights shall standard separation (vertical or horizontal) be provided? Include arrangements for aircraft in classes F&G.
Standard vertical or horizontal separation shall be provided between:
1) All flights in Class A airspace
2) IFR flights in Class C, D and E airspace
3) IFR flights and VFR flights in Class C airspace
4) IFR and SVFR flights
5) SVFR flights, except where a reduction is authorised by the CAA.
Standard separation shall be provided, in so far as possible, between flights that have flight planned to operate on Class F ADR airspace.
In Class G airspace, separation between aircraft is ultimately the responsibility of the pilot. However, in providing a Deconfliction Service or Procedural Service, controllers will provide advice aimed at achieving a defined deconfliction minima.

According to MATS Pt 1, what is a loss of separation and what are a controllers actions when faced with the situation?
If, for any reason, a controller is faced with a situation in which two or more aircraft are separated by less than the prescribed minima, e.g. ATC errors or differences in the pilots estimated and actual times over reporting points, he is to:
1) Use every means at his disposal to obtain the required minimum with the least possible delay and,
2) When considered practicable, pass traffic information if an ATS surveillance service is being provided, otherwise, pass Essential Traffic Information.
What are the vertical separation minima, as described in MATS Pt 1?
Vertical separation exists when the vertical distance between aircraft is never less than the prescribed minimum. Th vertical separation minima are:
1) Between aircraft flying subsonic:
a) Up to FL290 apply 1000ft
b) Above FL290 apply 2000ft, except that between FL290 and FL410 inclusive, 1000ft may be applied between RVSM approved aircraft operating in airspace designated as being notified for the application of this separation standard.
2) Between aircraft flying supersonic and between aircraft flying supersonic and aircraft flying subsonic:
a) Up to FL450 apply 2000ft
b) Above FL450 apply 4000ft
Define the term ‘exact reporting point’, according to MATS Part 1
An ‘exact reporting point’ is a position established by a navigational facility which is:
1) overhead a VOR
2) overhead an NDB
3) a position notified as a reporting point and which is established by the intersection of VOR radials, or of a VOR radial and a bearing from an NDB
4) a position established by a VOR radial combined with a range from a co-located or associated DME.
According to MATS Pt 1, how is lateral separation applied and how is it achieved?
Lateral separation shall be applied so that the distance between aircraft is never less than a specified amount. It is achieved by requiring aircraft to fly on different tracks or in different geographical locations as determined by visual observations or by use of navigational aids.
According to MATS Pt 1, how is longitudinal separation applied and how is it achieved?
Longitudinal separation based on either time or distance shall be applied so that the spacing between the estimated positions of the aircraft being separated is never less than a prescribed minima. It is achieved by requiring aircraft to:
1) Depart at a specified time
2) Lose or gain time to arrive at a geographical location at a specified time or
3) Hold over a geographical location until a specified time
