Haditengerészetnél mi az a tisztelgő füttyszó?

Tengerész jelzősíppal és sorfallal köszöntik tradicionálisan a haditengerészetek a fedélzetre lépő magasrangú tiszteket és fontos személyeket. (A sípszó egyben jelzés a legénységnek is a fegyelmezett viselkedésre.)

“ A boatswain's call, pipe or bosun's whistle is a pipe or a non-diaphragm type whistle used on naval ships by a boatswain. It is pronounced, and sometimes spelled, "bosun's call".

...

Pipe aboard: Flag-rank officers or an important guest is boarding a Navy ship. This is part of a ceremony called "manning the side" which includes a party of sailors known as "side boys". It has its origins in the need to hoist visiting senior officers aboard using a bosun's chair when the weather was too rough for the use of ladders. The bosun would use his call to direct the side boys in the hoisting of the chair”
