NOTES
DDAS* This figure indicates the number of days helicopters are capable of deploying
aboard ships per the DDAS definition. (If DAHS limit has been reached, DDAS can be
converted to DAHS. Such transfers are permitted as long as the total annual deployed days
does not exceed the above combined DDAS/DAHS total. DAHS should not be converted
to DDAS due to increased maintenance costs associated with DDAS.)
(1) DAHS to accommodate special operations consisting of a 365 day deployment
requirement. The number of 365-day requirements will drive the number of scheduled
mission aircraft required for support.
(2) These standards (number of days deployed/away) can only be accurately calculated to a
point. However, when calculating air stations with large numbers of scheduled mission
aircraft (i.e., more than two), the cumulative affect of aircraft transiting to and from the
OPAREA, and the increased down time competing for maintenance/parts will reduce the total
number of DDAS/DAHS.
(3) Actual DAHS will vary based on Air Eye tasking. If DAHS exceed 30, unit SAR readiness
may be negatively impacted due to decreased aircraft availability.
(4) Air Station Traverse City operates AIRFAC for only 6 months, which enables 50
additional DDAS.
(5) Air Station Atlantic City supports AIRFAC Gabreski with a dual crew from 15 April to 15
October and maintains a second B-0 at the parent command. Supporting the AIRFAC with a
dual crew reduces their DDAS standard requirement by 180 days.
(6) Air Station Kodiak supports AIRFAC Cordova from 15 April to 15 October. Days
supporting AIRFACs do not count towards the DAHS total.
