Taxiing phase reworked to take into account rejected takeoff periods.
Takeoff acceleration threshold increased to 0.15g to avoid enthusiastic taxiing being identified as a takeoff start.
"Takeoff Roll Or Rejected Takeoff" phase introduced to cover KPVs that relate to unsafe acceleration towards a takeoff.
Takeoff Acceleration Start KTI amended to use the offset removed acceleration signal. Minor improvement.
