i was wondering if the dev's are able to make an odometer readout in the speed gauge, thats readable,
and can be used for manual navigation. sh1 had one, sh2 sh3 sh4 does not. there are only two ways to navigate, by celestrial navigation and dead reckoning. overcast skies limits the use of celestrial navigation, but dead reckoning can be used anytime, in fact thats what the way point tool does really, its DR, but the calculations are done automatically for us, i would like to do the calculations myself, by drawing true courses on the map, without the waypoint tool. Dead Reckoning Dead reckoning is the process of navigation by advancing a known position using course, speed, time and distance to be traveled. In other words, figuring out where you will be at a certain time if you hold the speed, time and course you plan to travel. Prior to the development of celestial navigation, sailors navigated by deduced (or dead) reckoning. Columbus and most other sailors of his era used this method. In dead reckoning, the navigator finds his position by estimating the course and distance he has sailed from some known point. Starting from a known point, such as a port, the navigator measures out his course and distance from that point on a chart, *****ing the chart with a pin to mark the new position.
