Where 7600 fits
Why 7600 is special
It tells air traffic control that the aircraft is airworthy but cannot hear or answer, at which point controllers clear airspace around it and expect it to follow its filed flight plan. Procedures exist for this precisely because it is not rare.

7 × 1,000 + 6 × 100 = 7,600. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

A general emergency and a radio failure. Flight-tracking sites display both automatically, which is why an in-flight emergency is often public before any airline statement.

7600 tells controllers the aircraft is flying normally but cannot transmit or receive. They then clear airspace and expect it to follow its filed plan, and the fact that detailed procedures exist reflects how routine radio failure is.
