Computes the equal-time-point (ETP), also called the critical point (CP).
This is the point along a route where it takes the same time to continue to
the destination as it does to return to the departure point.
Two separate ground speed parameters allow the consumer to account for wind:
the ground speed continuing to the destination may differ from the return
ground speed.
Parameters
totalDistanceNm: number
Total route distance in nautical miles.
groundSpeedOutKt: number
Ground speed continuing toward the destination in knots.
groundSpeedBackKt: number
