b) a manoeuvre restriction intended to maintain existing separation. Resolution advisory complement (RAC). Information provided by one ACAS to another via a Mode S interrogation in order to ensure complementary manoeuvres by restricting the choice of manoeuvres available to the ACAS receiving the RAC. Resolution advisory complements record (RAC record). A composite of all currently active vertical RACs (VRCs) and horizontal RACs (HRCs) that have been received by ACAS. This information is provided by one ACAS to another ACAS or to a Mode S ground station via a Mode S reply. Resolution advisory strength. The magnitude of the manoeuvre indicated by the RA. An RA may take on several successive strengths before being cancelled. Once a new RA strength is issued, the previous one automatically becomes void. Resolution message. The message containing the resolution advisory complement (RAC). Reversed sense RA. A resolution advisory that has had its sense reversed. Chapter 4 Annex 10 — Aeronautical Telecommunications 4-3 22/11/07 Sensitivity level (S). An integer defining a set of parameters used by the traffic advisory (TA) and collision avoidance algorithms to control the warning time provided by the potential threat and threat detection logic, as well as the values of parameters relevant to the RA selection logic. Threat. An intruder deserving special attention either because of its close proximity to own aircraft or because successive range and altitude measurements indicate that it could be on a collision or near-collision course with own aircraft. The warning time provided against a threat is sufficiently small that an RA is justified. Track. A sequence of at least three measurements representing positions that could reasonably have been occupied by an aircraft. Traffic advisory (TA). An indication given to the flight crew that a certain intruder is a potential threat. Vertical speed limit (VSL) RA. A resolution advisory advising the pilot to avoid a given range of altitude rates. A VSL RA can be either corrective or preventive. Warning time. The time interval between potential threat or threat detection and closest approach when neither aircraft accelerates. 4.2 ACAS I GENERAL PROVISIONS AND CHARACTERISTICS 4.2.1 Functional requirements. ACAS I shall perform the following functions:
