107 - Passing Traffic Flashcards
Glossary > 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.
Traffic Information Exceptions
If the target of an identified IFR or CVFR aircraft appears likely to come in proximity to another observed target to warrant the pilot’s attention, 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
Traffic Information > Who do we provide traffic information to?
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[6], equipment limitations[7], or higher priority duties[8] prevent you from doing so.
[6] In this context, workload means traffic volume, traffic complexity, radio frequency congestion, coordination, or other control-related duties. It does not include system limitations created by on-the-job training, staffing, employee periods of relief, or other workplace constraints.
[7] Limitations can occur when communications or ATS surveillance equipment becomes degraded or unserviceable.
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.
- A pilot requests it.
- A pilot acknowledges an avoidance instruction.
- You consider it necessary.
Traffic Information Format
When issuing traffic information to aircraft, as appropriate, include:
1. Position of aircraft
2. Direction of flight
3. Type of aircraft or relative speed
4. Altitude of aircraft
5. Reporting point and time
6. Other information
When to state “Clear of previous traffic”
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.
Traffic Passing > Holding
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).”
Control Service
Give priority to providing control service. Provide other services to the fullest possible extent.
Traffic Information
Traffic information may be based on:
* Observation of identified or unidentified targets
* Reports from pilots or other ATS facilities
