Oh dear Dancing Bear*, I fear you had better stick to being an "Aviation Instructor", whatever that is! You are way off beam on this one since the original reference was to naval officers in Nelson's time.
To save you doing any research, in the spirit of my suggestion to Silsoe Sid, Nelson died on 21 October 1805, Queen Victoria acceded to the throne on 20 June 1837 and, quite separately, the present arrangements for the wearing of swords were approved in 1856. And oh, I have checked both my No 5 (Old number)/No 1 (New number) uniform jacket and my greatcoat, and both have provision for hooking up one's sword, and have been used accordingly many times.
If that's not good enough for you, have a look at the Cenotaph ceremony on 11 November and you should clearly see that those members of the Royal Family, their naval equerries, and other naval officers present, wear their swords accordingly, thus indicating that there is absolutely no such bar, especially not for the reason you so fancifully and inaccurately suggest.
With renewed apologies to Marcus that his splendidly positive thread should have degenerated into such petty strife, but I do feel it right to set the record straight.
