2-4. HELMET FITTING AND OPERATION
Following is the procedure for donning and fitting the helmet, operating the helmet components,
and removing the helmet.
Tools and Materials Required
•
Needle and thread
•
Small cross-tip screwdriver
NOTES:
•
Ensure that the correct helmet size has been selected as described in Paragraph 2-2
(Page 5).
•
If night vision goggles are to be used, check helmet fit with the goggles attached.

In preparation for the fitting procedure, females with long hair should arrange their hair so
that it is completely covered by the helmet and/or the flight suit. The hair must be worn the
same way thereafter.
Procedure
1. Before having the wearer
don the helmet, verify that:
•
the TPL or SCL seats down
against, and is aligned
with, the front edge of the
energy-absorbing liner, and
that the TPL or SCL is
centered in the helmet.
•
the holes in the front of the
TPL or SCL align with the
holes in the energy-absorbing
liner as shown in
Figure 2-42
.

Proper fitting is essential to the functioning of the helmet, all of its components,
and, consequently, the safety of the wearer. Take as much time as necessary to fit
the helmet precisely. Use extreme care in taking measurements and checking fit.
