CM-0811 — Enhanced STCA for TMA specific operations

STCA enhancements aim at reducing nuisance alert rate while maintaining or increasing the genuine alert rate and increasing alert warning times.
STCAs enhancement will be based on advanced algorithms as enablers for greater warning times, lower false and nuisance alert rates for steady and manoeuvring aircraft, either horizontally or vertically by the implementation and the use of curved or multi-hypothesis predictions (i.e. computed extrapolations).
For example, depending on parameter setting:
1 -The main hypothesis : the trajectory expected to be followed which can be a straight line, or curved taking into account things like: Cleared Flight Level (CFL), Standard Arrival Routes (STAR), Holding pattern etc.
2 -The backup hypothesis: a straight line extrapolation (computed only if the main hypothesis is not a straight line

Rationale
Safety Nets are not yet implemented or not operationally useable in some specific ATC control operations e.g. dense TMA operations as well as complex relief or hazard configurations, because of poor alerting performance. Because the nuisance alert rate is too high; there is a real risk that controllers do not trust Safety Nets and therefore do not use those functions.
