Note: The filament may be fully closed in plan, or may embrace an arc of less than 360 degrees.

In the latter case, the French term is Grille Tronconique Incomplete or Filament Tronconique Incomplet and the English term is"Bunch filament" (2-3-220).




Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
