Separation Flashcards
According to MATS Part 1, when shall standard separation be increased?
Standard separation shall be increased when:
a) Requested by the pilot
b) A controller considers it necessary
c) When directed by the CAA
When may standard separation be reduced? (Ignore in the vicinity of aerodromes)
Standard separation may be reduced when:
a) Authorised by the CAA and published in MATS Part 2
b) Standard separation may be reduced when a SAR aircraft is escorting an aircraft in emergency. A minimum is not laid down in UK FIR’s and separation may be reduced to that which can be maintained visually or with an airborne radar
c) Reduced separation may be applied during surveillance system failure
In the context of applying longitudinal separation, define the following terms as per MATS Part 1
Same track
Reciprocal track
Crossing tracks
Same track: When the track of one aircraft is separated from the track of another aircraft by less than 45 degrees
Reciprocal track: When the track of one aircraft is separated from the reciprocal track of another aircraft by less than 45 degrees.
Crossing tracks: Intersecting tracks which are not classed as “same” or “reciprocal”.
State the minimum time separations (as specified in MATS Part 1) that may be used between aircraft at the same cruising level and on the same track, and detail any associated provisions.
2 minutes - Provided the 2 minute departure separation has been applied
3 minutes - When specifically authorised by the CAA, provided both aircraft are equipped with functioning transponders, are continuously monitored by radar and the actual distance between them is never less than 20 miles.
5 minutes - When specifically authorised by the CAA, provided both aircraft are equipped with functioning transponders, are continuously monitored by radar, the actual distance between them is never less than 30 miles and provided the preceding aircraft has filed an airspeed of 20 knots or greater than the following aircraft.
Otherwise 10 minutes
