b) either: 1) the altitude separation test (4.4.2.1) gives a negative result; or 2) confidence in the tracked altitude rate of the intruder is “low” and no resolution manoeuvre would provide a predicted separation of at least At (4.4.2.2), whether the threat had an altitude rate equal to the upper altitude rate bound, to the lower altitude rate bound, or to any altitude rate between these bounds (4.1.3.3.4); or 3) there is “low” confidence in the threat’s tracked altitude rate, the current altitude separation is greater than 46 m (150 ft), and the RA that would be selected against the threat when considered separately from other possible threats would be altitude crossing. 4.4.2.1 ALTITUDE SEPARATION TEST 4.4.2.1.1 The altitude rate of own aircraft is declared “small” if ≤Ô5. 4.4.2.1.2 The value 3.0 m/s (600 ft/min) is used for Ô5. 4.4.2.1.3 The delay in threat declaration is declared “acceptable” if it is less than 3.0 s. 4.4.2.1.4 The maximum altitude separation threshold, Ac, is given a value of 260 m (850 ft), when the vertical rates of own and of the threat are in the opposite directions and neither of them is “small”, and a value of 183 m (600 ft) otherwise. 4.4.2.1.5 Altitude separation is declared “minimum” if it is equal to 100 ft. 4.4.2.1.6 An encounter is declared “slow closing” if the range rate is greater than Dm/T. 4.4.2.1.7 Test conditions. The altitude separation test gives a negative result if the threat is a new threat and the RA that would be selected against the new threat when considered separately from other possible simultaneous threats would be either:
