c) when the intruder is equipped and responds 0.04. 4.4.4 Compatibility with air traffic management (ATM) 4.4.4.1 NUISANCE ALERT RATE 4.4.4.1.1 Under the conditions of 4.4.2, the collision avoidance logic shall be such that the proportion of RAs which are a “nuisance” (4.4.4.1.2) shall not exceed: .06 when own aircraft’s vertical rate at the time the RA is first issued is less than 400 ft/min; or .08 when own aircraft’s vertical rate at the time the RA is first issued exceeds 400 ft/min. Annex 10 — Aeronautical Telecommunications Volume IV 22/11/07 4-44 Note.— This requirement is not qualified by the ACAS equipage of the intruder (4.4.2.7) since it has negligible effect on the occurrence and frequency of nuisance RAs. 4.4.4.1.2 An RA shall be considered a “nuisance” for the purposes of 4.4.4.1.1 unless, at some point in the encounter in the absence of ACAS, the horizontal separation and the vertical separation are simultaneously less than the following values: horizontal separation vertical separation above FL100 2.0 NM 750 ft below FL100 1.2 NM 750 ft 4.4.4.2 COMPATIBLE SENSE SELECTION Under the conditions of 4.4.2, the collision avoidance logic shall be such that the proportion of encounters in which following the RA results in an altitude separation at closest approach with the opposite sign to that occurring in the absence of ACAS shall not exceed the following values:
