earing the aircrew integrated helmet system (AIHS) can be uncomfortable if
you just jam it on your noggin.
A good Ft starts with the right size helmet. Your beret size is
not
your helmet size!
Before you pick up your helmet from CI±, visit the ALSE shop to get your head
measured. Measuring instructions can be found in TM 1-1680-377-13&P on IETM
EM 0250.
After picking up your helmet, you will need to go back to the ALSE shop. Your
technician will use the information in the IETM to Ft your helmet.
Your job is to put the helmet on right!
Press the helmet down Frmly with both hands to ensure the helmet is properly
positioned on your head. Then fasten and adjust the chinstrap.
Now adjust the nape strap.
Pull the nape strap pad down and
tighten the adjustment straps. If
you don’t, the helmet’s unstable
and will put your noggin at risk
of injury.
If your helmet is too tight
or too loose, let your ALSE
Tech know so he can adjust
your helmet liner to improve
comfort.
If you have long hair, make sure it is
down and flat in the back. If you change
your hairstyle, you’ll need to recheck that
your helmet Fts properly.
If you and your ALSE Tech cannot get a
good Ft using the procedures in the IETM,
the US Army Aviation Research Lab
(USAARL) has a special Ft program. Your
ALSE tech can get you in touch with them.
Operator PMCS and cleaning procedures
can be found in the IETM too.
A good helmet Ft always includes
frequent inspections, keeping it clean and
dry and looking for parts that are worn or
frayed. Let your ALSE techs know what
needs attention.
