Detailed Description

This class is used to determine if one aircraft has priority over another aircraft. It is an encapsulation of the "right of way" rules.

Disclaimer: The current rules have been verified to have certain safety and liveness properties, but they have not been validated, that is, they may not behave "naturally." As we learn more about what is expected, these rules may evolve in the future.

sortValue()

double larcfm::TargetUrgency::sortValue ( double  cdist, bool  conflict, double  tin, double  tca, double  dist_tca, double  B, double  T  )

static

Return a priority ranking value far an aircraft s.t. if two ranking values are compared, the lower (possibly negative) value will represent the most urgent aircraft.

Parameters

cdist	current distance between aircraft, in meters
conflict	true if a conflict was detected
tin	time in for the conflict, in seconds (if conflict)
tca	critical time of conflict, in seconds (if conflict)
dist_tca	distance at critical time, >= 0.0 (if conflict)
B	detection start time (generally 0)
T	detection lookahead time, t <= 0 is "no data"

Returns

urgency sorting value, with positive infinity being least urgent and negative infinity being most urgent
