Why do you think nautical miles is regression?
They are super convenient for air travel as it automatically takes into account how high up you are. If you have traveled 10 nautical miles at sea level and 10 nautical miles at 10km altitude both planes have covered the same ground distance. If you travel 10km at sea level you cover exactly that distance compared to the ground, a plane that travels 10km at 10km altitude will differ in ground covered by about 15m. Which doesn’t sound much but very much adds up when traveling the globe.
Because they didn’t travel at a height that mattered enough in distance traveled compared to ground level, they also didn’t travel far enough for that to matter.
for me the solution should be to able to change them to whatever we want even if its unrealistic. Don’t force people that only know Metric system use Imperial one and vice versa
At the end of the day what measurements you or your countries use’s is not relevant to this topic so use whatever you want to use and leave it at that.
I just realised the A7D is at the same BR as the Jaguar GR1A in GRB while having better A2G then the Tornado GR1 at 12.0 bruh how the hell did the Buc S2B go to 11.7 but the A7D is 11.0
