| Aircrew | Controller | |||||
|---|---|---|---|---|---|---|
| Traffic advisory (TA) | ||||||
| Shall not manoeuver their aircraft in response to traffic advisories (TAs) only | Remains responsible for ATC separation | |||||
| Should prepare for appropriate action if an RA occurs; but as far as practicable, pilots should not request traffic information | If requested by the aircrew, shall give traffic information | |||||
| Resolution advisory (RA) | ||||||
| Shall respond immediately and manoeuver as indicated, unless doing so would jeopardize the safety of the airplane | Shall not attempt to modify the flight path of an aircraft responding to an RA | |||||
| Shall follow the RA even if there is a conflict between the RA and an Air Traffic Control (ATC) instruction to manoeuver | Shall not issue any clearance or instruction to the aircraft involved until the pilot reports returning to the terms of the assigned ATC clearance or instruction | |||||
| Shall never manoeuver in the opposite sense to an RA, nor maintain a vertical rate in the opposite sense to an RA | Shall acknowledge the report by using the phrase "ROGER" | |||||
When deviating from an air traffic control instruction or clearance in response to any RA, shall:
|
If requested by the aircrew, shall give traffic information | |||||
| Shall promptly comply with any subsequent RAs issued by TCAS | Ceases to be responsible for providing separation between that aircraft and any other aircraft affected as a direct consequence of the manoeuver induced by the RA, as long as the pilot reported the TCAS RA. | |||||
| Shall limit the alterations of the flight path to the minimum extent necessary to comply with the resolution advisories | ||||||
| Clear of conflict (CC) | ||||||
| Shall promptly return to the terms of the ATC instruction or clearance when the conflict is resolved | Shall resume responsibility for providing separation for all the affected aircraft when he acknowledges:
|
|||||
| Shall notify ATC after initiating a return to or resuming the current clearance | ||||||

Famous quotes containing the words pilot, interaction and/or event:
“Whenever the weather licks the pilot instead of him lickin’ the weather, he’s finished. The first time makes the second time easier. And the first thing he knows, he’s in trouble when the weather is perfect.”
—Frank W. Wead (1895?–1947)
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“... every event has had its cause, and nothing, not the least wind that blows, is accident or causeless. To understand what happens now one must find the cause, which may be very long ago in its beginning, but is surely there, and therefore a knowledge of history as detailed as possible is essential if we are to comprehend the past and be prepared for the future.”
—Pearl S. Buck (1892–1973)
