This was the most common version of the H-5, used on jets, propeller aircraft and helicopters.
This version was the standard headgear of Swiss AF pilots until the mid 1980's. It features the following characteristics:
"Gull wing cut" in the area above the pilot's eyes, in order to improve visibility;
Improved Internal padding;
British Mk.-2 visor reshaped to match and not interfere with
A-13 A/ MS22001 oxygen mask and receivers;
Installation of cast oxygen mask receivers;
Single plug comm connector;
Repositioned rear comm cable exit with supplemental leather hose removed in order to avoid excessive cable tension;
Installation of boom mike "banana mount";
This specimen is shown with a MS22001 oxygen mask, the latter being modified with supplemental diluter valve and the so-called "Röhrli" (Swiss german for "thin hose") hose, suitable for FFW
C-3605, Pilatus P-2/ 05 and PC-6 Porter oxygen systems.
