SPH-4 

 

Standard configured SPH-4, the first specifically dedicated helicopter helmet of the Swiss AF. If required it could also be used on propeller aircraft like the Pilatus PC-6 and PC-7.

A small number of SPH-4 are still in the Swiss AF inventory as loaner helmets, issued temporarily to pilot school candidates during the first screening/selection phase. 

 

During its SAF service life the SPH-4 was fitted with (ANVIS), i.e. AN/AVS-6 and  AN/AVS-9.
