4.4.2.6.3.3 Verticul accelerution
4.4.2.6.3.3.1 Subject to 4.4.2.6.3.2.5, for aircraft that are not level over the entire encounter window, the rate shall be
constant and equal to i, over ar least the interval [tca - 40 s, tca - 35 s] at the beginning of the encounter window, and
shall be constant and equal to iz over at least the interval [tca + 5 s, tca + 10 s] at the end of the encounter window. The
vertical acceleration shall be constant in the intervening period.
4.4.2.6.3.3.2 The vertical acceleration (i) shall be modelled as follows:
where the parameter A is case-dependent as follows:
A($-')
Case Layers 1-3 Layers 4-6
and the error E is selected randomly using the following probability density:
where p = 0.3 ft s".
N o t e . The sign of the acceleration is determined by i, and i2 . An error E that reverses this sign must be rejected
and the error reselected.
