Human Systems Integration Capstone. / Unlimited distribution. / Expeditionary Helicopter Sea Combat Squadrons (HSC) operate on Navy amphibious assault ships to provide search
and rescue (SAR), logistics and combat support. When embarked, the detachments are the primary SAR asset and
have requirements levied upon them by NAVAIR 00-80T-106 to maintain aircraft SAR readiness postures in support of
ship and embarked Marine Corps aircraft operations.
The goal of this study was to identify what impacts would occur to flight support personnel effectiveness if OPNAV
3710.7U sleep requirements were deviated from in order to meet minimum personnel requirements. The conclusion
reached was that safety concerns are present when OPNAV 3710.7U sleep requirements for flight support personnel
are violated to maintain NAVAIR 00-80T-106 operational requirements. The study found that worker effectiveness
varies systematically with the duration of sleep interruption encountered. Minimum predicted effectiveness comes at
three hours with the predicted values at two, three and four hours being essentially equal. When sleep interruptions
exceed 1.55 hours, effectiveness levels drop below 70%, equivalent to experiencing a .08 BAC. A model for
subsequent interruptions over the preceding days found that worker effectiveness varies systematically with the
number of days between interruptions. The effect of sleep interruptions of multiple nights was greatest two days
between interruptions. A minimum of four to five days between sleep interruptions is required for interruption effects to
not be cumulative.
