I am not as proficient in FSX/B52Driver as y'all, but I do have a comment. Back before many of y'all were born I was flying B52s and the only nav we had was TACAN (useless outside CONUS), radar, and celestial (Overwater).

So, perhaps  the perceived shortcomings on B52 Driver navaids are actually realistic. Of course, if CS would add a periscopic sextant to the package, realism would be enhanced!
