At least they are accurate enough for the customer acceptance tests. Coriolis force was just a parenthetical addition, but I remember a project where the customer paid extra to remove the Coriolis correction but later paid even more to get it back in.

As a retired Software Engineer I would like to add my 2c. Long ago I was writing computer programs to aim big guns on warships to targets some 30 km away.
Of course all calculations are in a orthogonal frame of reference.
We did have to correct for the earth curvature and also for refraction. (BTW, also for the Coriolis force)
