ATC 용어집 (t)

1. (Taxi into) Position and Hold

2. THAT IS CORRECT- The understanding you have is right

활용) Your read back is correct,처럼 That 자리에 잘나오는 것이 Read back

3. TRAFFIC ADVISORIES- Advisories issued to alert pilots to other known or observed air traffic which may be in such proximity to the position or intended route of flight of their aircraft to warrant their attention. Such advisories may be based on:

a. Visual observation.

b. Observation of radar identified and nonidentified aircraft targets on an ATC radar display, or

c. Verbal reports from pilots or other facilities.

Note 1: 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."

Note 2: 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/her 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/she should not assume that all traffic will be issued.

활용) 특히 radar traffic에 대한 조언, 진행방향, 고도, 방위, 추가 정보(항공기 기종등)

4. TRAFFIC IN SIGHT- Used by pilots to inform a controller that previously issued traffic is in sight.

활용) Traffic insight 의 경우 주로 VFR에서 사용, Radar 있는 항공기에서는 contact 이라는 말을 주로 사용한다

5. TRAFFIC NO FACTOR- Indicates that the traffic described in a previously issued traffic advisory is no factor. - Traffic No (Longer A) Factor = Clear of traffic

활용) 잠재적인 충돌 요인들이 더 이상 없을 때, 즉 ATC에서 Traffic advisory를 주었는데 조종사가 traffic을 보지 못했을 때 (Negative contact, Not in sight, Looking) 허나 이 상황이 모두 지나가서 안전한 상황이 되었을 때 ATC가 Pilot에게 이제는 안전 하다는 정보 제공하기 위해서

6. TRAFFIC NO LONGER OBSERVED- Indicates that the traffic described in a previously issued traffic advisory is no longer depicted on radar, but may still be a factor.

활용) 관제사의 Radar coverage를 벗어났을 때 Radar contact lost의 의미

7. TRANSITION-

a. The general term that describes the change from one phase of flight or flight condition to another; e.g., transition from en route flight to the approach or transition from instrument flight to visual flight.

b. A published procedure (DP Transition) used to connect the basic DP to one of several en route airways/jet routes, or a published procedure (STAR Transition) used to connect one of several en route airways/jet routes to the basic STAR.

활용)

1) Definition으로 비행 방식을 VFR→IFR, IFR→VFR을 바꿀 때

2) ATC에서는 DP(Departure procedure)에서 Transition route(항로까지 이어주는 것)으로 이어주는 것

3) Flight level transition altitude

4) 항공기가 어떤 Airspace Volume을 지나갈 때

8. Type and Altitude Unknown

활용) Traffic advisory를 줄 때 altitude와 추가 정보를 주는데 관제사가 정보를 알지 못할 때, 대게 이런 종류의 항공기들은 저고도, 회전익 비행기들로 차폐되는 비행을 자주하여 radar에 잘 잡히지 않기도 함

9. TRACK- The actual flight path of an aircraft over the surface of the earth.
