Aviator's ValuPac 1.0(1)

the author of this app says:

Aviator's ValuPac contains two stand-alone applications for aviators.

Range & Bearing permits you to quickly compute the distance and relative directions between any two points on the earth, given their respective latitudes and longitudes.

The Aviator's Navigation Calculator operates in two modes. In Flight Planning Mode, it quickly computes true and magnetic headings, track speed, time en route and time of arrival for a flight leg.

In Enroute Mode, it allows you to update the true or magnetic heading required to maintain your track and uses this information to calculate the actual winds and the impact they are having on your ground speed and time en route.
