What is the lookahead time of 4CAS?
Research shows that 3 minutes is typically sufficient to execute most avoidance maneuvers. And setting the lookahead too high typically leads only to frequent false alarms and added pilot confusion. So we currently have the lookahead set at 6 minutes. However, all it takes is changing a single number in the code and recompiling the program to set lookahead at any value.
