b) confidence in the tracked rate is declared “low” when altitude reports are missing for two or more successive cycles. 4.2 Traffic advisories (TAs) 4.2.1 TA GENERATION 4.2.1.1 A TA is generated for an intruder reporting Mode C altitude when the application of both a range test (4.2.3) and an altitude test (4.2.4) gives a positive result for each in the same cycle of operation. 4.2.1.2 A TA is generated for an intruder equipped with a non-altitude-reporting transponder when the result of applying a range test (4.2.3) is positive. 4.2.2 TA WARNING TIME For intruders reporting altitude, the range test for TAs gives a nominal warning time as follows: S TA warning time T+10 T+10 T+10 T+15 T+15 T+13 where S = sensitivity level 4.2.2.1 The values for T for sensitivity levels 3 to 7 are those given in 4.3.3.3.1. The value for T for sensitivity level 2 is 10 s. 4.2.3 TA RANGE TEST The range test for TAs has the same form as that used for threat detection (4.3.3). The values used for Dm for sensitivity levels 3 to 7 are those given in 4.3.3.1.1 incremented by g(Tw – T)2/6 where Tw is the desired TA warning time. The base value for Dm for sensitivity level 2 is 0.19 km (0.10 NM). 4.2.4 TA ALTITUDE TEST The altitude test gives a positive result if one of the following sets of conditions is satisfied:
