(1) Visual observation, (2) Observation of radar identified and non identified aircraft targets on an Air Traffic Control radar display, or, (3) Verbal reports from pilots or other facilities. The word "traffic" followed by additional information, if known, is used to provide such advisories; e.g., "Traffic, 2 o'clock, one zero miles, Southbound, eight thousand." Traffic advisory service will be provided to the extent possible depending on higher priority duties of the controller or other limitations, e.g., radar limitations, volume of traffic, frequency congestion or controller workload. Radar/nonradar traffic advisories do not relieve the pilot of his responsibility to see and avoid other aircraft. Pilots are cautioned that there are many times when the controller is not able to give traffic advisories concerning all traffic in the aircraft's proximity; in other words, when a pilot requests or is receiving traffic advisories, he should not assume that all traffic will be issued. "(Identification), traffic alert, advise you turn left/right (specific heading if appropriate), and/or climb/descend (specific altitude if appropriate) immediately." (See Safety Alert) TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM/TCAS - An airborne collision avoidance system based on radar beacon signals which operates independently of ground based equipment. TCAS-I generates traffic advisories only. TCAS-II generates traffic advisories, and resolution (collision avoidance) advisories in the vertical plane. TRAFFIC INFORMATION (P/CG) - (See Traffic Advisories) TRAFFIC INFORMATION (RADAR) (JCS) - Information issued to alert an aircraft to any radar targets observed on the radar display which may be in such proximity to its position or intended route of flight to warrant its attention. TRAFFIC IN SIGHT - Used by pilots to inform a controller that previously issued traffic is in sight. (See Negative Contact, Traffic Advisories) TRAFFIC MANAGEMENT PROGRAM ALERT/TMPA - A term used in a Notice to Airmen (NOTAM) issued in conjunction with a special traffic management program to alert pilots to the existence of the program and to refer them to either the Notices to Airman publication or a special traffic management program advisory message for program details. The contraction TMPA is used in NOTAM text. TRAFFIC NO FACTOR - Indicates that the traffic described in a previously issued traffic advisory is no factor. TRAFFIC PATTERN - The traffic flow that is prescribed for aircraft landing at, taxiing on, or taking off from an airport. The components of a typical traffic pattern are upwind leg, crosswind leg, downwind leg, base leg and final approach. (1) UPWIND LEG - A flight path parallel to the landing runway in the direction of landing. (2) (3) |
