of the Swiss AF inventory and "slow movers" like helicopters and Pilatus

helmet, in the quest of standardization and in order to reduce spare parts storage.

A peculiar feature of the "Swiss 316", compared to the "standard -316", was the different configuration of chin and nape strap, dark visor shade, communication cables, oxygen mask bayonet receivers and, as visible here, featuring upward pointing headset straps as on the

-317.

In accordance with BAMF T.O. (Technical Orders issued by the Federal Office for Military Aerodromes), a boom mike bracket has been fitted.
