About Nautical Calculator Pro
Nautical Calculator Pro is the most complete application that solves the navigation calculations
The main features are :
- Calculate Route (solves 2nd navigation problem)
- Calculate point on Rhumb Line (solves 1st navigation problem)
- Calculate point on Great Circle (solves 1st navigation problem)
- Calculate point on WGS84 (solves 1st navigation problem)
- Calculate Average speed
- E.T.A. calculation
- Route plan, for manual waypoints planning
- Waypoint route
- Compisite sailing with parallel limit
- Rhumb Line Parallel/Meridian intersection
- Follow on same Rhumb Line route
- Opposite course rendez vous
- Route correction
- Calculate Amplitude at sunset and sunrise and magnetic compass deviation
- Compass detections
- Solves Drift problem
- Solves Tides problem
- Solves Tidal current problem
- Wind calculation with Beaufort classification
- ABC Tables (azimuth, initial course, right ascension with unknow star)
- Nautical almanac
- Celestial Navigation with position line
- Meridian transit
- Celestial observation
- Coastal navigation
- Wheel Over
- Draft survey
- Converter
- Anchorage
- Interpolation
In routes feature there is a world map: it isn't a nautical chart and is not for use as a saling chart, but as a simple general means of showing the courses through the water on earth, this map isn't for navigational purposes.
No need connection for show the map; the map will be downloaded only one time.
The map, for size limit, will be show for scale over 60-70 Nm.
