MATS 107 and 108 - SOURCE Flashcards
TRAFFIC INFORMATION
Information issued by ATS to pilots regarding other known or observed traffic that may be in such proximity to their position or intended route as to warrant their attention.
This card states when we MUST pass traffic
If the targets of identified IFR or CVFR aircraft ____________________, provide ATS surveillance traffic information, unless one of the following applies:
If the targets of identified IFR or CVFR aircraft
appear likely to merge with another observed target,
provide ATS surveillance traffic information, unless one of the following applies:
- The aircraft are known to be separated by more than the appropriate vertical separation minimum.
- The aircraft are established in a holding pattern.
Coles notes: Traffic must be passed to all identified IFR or CVFR aircraft if their targets will likely merge with any other ATS surveillance target, whether that target is known or not.
Unless they are separated by more than the minimum vertical separation, inform….
Unless they are separated by more than the minimum vertical separation, inform holding aircraft of other aircraft holding at the same fix.
TRAFFIC ( aircraft type ) HOLDING AT ( fix ) MAINTAINING ( altitude )
Coles notes: Although we are not required to pass traffic to aircraft in a holding pattern, we are required to inform aircraft that there are others in the holding pattern, unless they are separated by more than the minimum vertical separation.
Traffic information service is also provided to VFR aircraft under certain conditions:
Provide traffic information to pilots of aircraft in Class C and Class D airspace.
Provide traffic information to pilots of aircraft in Class E airspace, unless workload, equipment limitations, or higher priority duties prevent you from doing so.
This card seems to add some more conditions where you must pass traffic
Provide traffic information to all concerned aircraft if any of the following apply:
- You clear an aircraft to maintain at least 1000 feet on top.
- You clear an IFR aircraft to fly in accordance with VFR.
- Multiple aircraft are holding at the same fix and are separated by the vertical separation minimum.
TRAFFIC ( aircraft type ) HOLDING AT ( fix ) MAINTAINING ( altitude ) - A pilot requests it.
- A pilot acknowledges an avoidance instruction.
- You consider it necessary.
Traffic information falls under the broader category of flight information service, Traffic information is mandatory, with some exceptions listed below
Provide flight information service to all known aircraft operating within a flight information region, unless any of the following apply:
- The aircraft operator provides flight information service [1] [2]
- An operational factor such as workload[3] or equipment limitations[4] prevents you from providing the service.
In this context, workload means traffic volume, traffic complexity, radio frequency congestion, coordination, or other control-related duties.
Flight information service can be provided before departure or during any phase of flight, whether aircraft are operating within or outside controlled airspace.
You may use ATS surveillance equipment to provide flight information services within….
You may use ATS surveillance equipment to provide flight information services within any airspace that is within ATS surveillance coverage provided you are satisfied that the displayed ATS surveillance information is adequate.
It is not necessary to inform a pilot of your reason for not providing or for discontinuing flight information service.
Traffic information may be based on:
- Observation of identified or unidentified targets
- Reports from pilots or other ATS facilities
When issuing traffic information to aircraft, as appropriate, include:
- Position of aircraft
- Direction of flight
- Type of aircraft or relative speed
- Altitude of aircraft
- Reporting point and time
- Other information
Passing Traffic
Position
{ number } O’CLOCK ( number ) MILES
For identified aircraft, position may be described in terms of the 12 hour clock in relation to the aircraft distance
For unidentified aircraft, issue distance and direction in relation to a fix
Passing Traffic
Direction
{direction of flight} (more information)
EXAMPLES
Northbound, Eastbound, Westbound, Southbound, Inbound, Opposite Direction, From left to right
Passing Traffic
Type
{aircraft type / relative speed)
examples
- HELICOPTER
- TYPE UNKNOWN
- SLOW MOVING
- BOEING SEVEN THREE SEVEN
Passing Traffic
Altitude
{Altitude}
You may use altitude readouts to provide altitude information
UNVERIFIED - Only if you have not verified the readout
CLIMBING / DESCENDING - Only if altitude is changing
If you are not providing ATS surveillance separation, and the pilot of an identified aircraft states that they do not see the traffic that was issued….
If you are not providing ATS surveillance separation, and the pilot of an identified aircraft states that they do not see the traffic that was issued, inform the pilot when they are clear of traffic.
CLEAR OF PREVIOUS TRAFFIC [ traffic position ]
When relieving a controller from an operating position:[4]
- If the position is equipped with an electronic log-on system that records time preparing to accept responsibility for the control position, and time on duty in the position, log on according to unit directives. A trainee is expected to log on with the OJI and to log off when leaving the position.
- Observe operational situations and equipment.
- Listen to communications.
- Observe current and pending traffic.
- Verify the position transfer checklist.
- Correlate information.
- Inform the controller being relieved that the position has been reviewed and request a verbal briefing.
- Exchange all pertinent data and ask questions, as appropriate, to ensure understanding.
- After the verbal briefing, state, or otherwise indicate clearly to the controller being relieved, that position responsibility has been transferred.
