![]() ![]() No, not my posts.. ![]() About 2 or 3 years ago somebody posted something about the SH3 (or SH4) nautical mile, which isn't the same as real life. I've done some measurments on a test mission going NWSE at 2 and 7 knots over 6 hours, in smooth and 'rough'ish' seas, and found I'm getting the same distance traveled on each speed setting. @ 7 knots for 6 hours = 75.6km (75.6/6 = 12.6 -> 12.6/7 = 1.8) @ 2 knot for 6 hours = 21.5km => 1.79 I've just re-edited so it makes better sense RL: 1 Nautical Mile = 1852 m 1 minute of Arc = 1 Nautical mile 1 degree of arc (60 minutes of Arc) = 60 Nautical miles (111 km) SH3: 1 Nautical Mile = 1800m (traveling at 1 Knot sub speed) 1 minute of Arc = 2000m 1 degree of Arc (60 minutes of Arc) = 120km Wot a mess ? As long as you keep the differences in mind you shouldn't have a navigation problem. Funny enough it still seems that the stars, sun and moon 'rotate normally' as per SH3's grid.
