b) either: 1) the altitude test gives a positive result; or 2) an altitude-crossing RAC has been received from the threat. 4.3.2.1 Established threat. The threat status of an established threat is maintained on successive cycles if, as a minimum, the range test gives a positive result. Annex 10 — Aeronautical Communications Volume IV 22/11/07 ATT-46 4.3.3 RANGE TEST 4.3.3.1 Range convergence. Aircraft are considered converging in range if the estimated range rate is less than tR . In this case the range rate estimate used in the range test is the minimum of the estimated range rate and tR − . 4.3.3.1.1 The value 3 m/s (6 kt) is used for tR . 4.3.3.2 Range divergence. Aircraft that are not considered converging in range are considered diverging in range. Range divergence is considered “slow” if the product of the estimated range multiplied by the estimated range rate is less than m P . 4.3.3.2.1 The following values are used for m P : S 4 to 6 m P km2/s ( m P NM2/s 0.0069 0.0020 0.0096 0.0028 0.0137 0.0040) 4.3.3.3 Range test criteria. The range test gives a positive result when one of the following conditions is satisfied:
