Application of hours flown. Hours flown in any
month apply to the extent of hours available.
(a)
First, to meet flight requirements for that month.
Any flight time remaining after this is considered
excess flight time. Excess flight hours may only be
used to make up flight deficiencies under the same
flight orders during which the excess flight hours were
accumulated. Excess flight hours are lost when the
flight orders under which they were earned are terminated.
(b)
Next, if the member has entered a "grace" period for
meeting flight requirements, to the prior month or
months within the "grace" period, as applicable (does
not apply to members issued periodic flight orders).
(c)
Next, in order, to the first, second, third, fourth,
and fifth succeeding months, but only to the extent
that the member fails, during each such month, to fly
the required four hours (does not apply to members
issued periodic flight orders).
(5)
Military operations or unavailability of aircraft.
This paragraph only applies to Coast Guard aviation units
that normally have a requirement for assigned members to
participate in frequent and regular aerial flight (does not
apply to members issued periodic flight orders).
(a)
Commanding officers of such aviation units are
authorized to certify that a member is unable to
meet normal flight requirements because military
operations (combat or otherwise) or the unavailability
of aircraft prevents the completion of such requirements.
Unavailability of aircraft is defined as a highly
unusual event that renders it virtually impossible for
a member to earn HDIP or monthly ACIP, such as a
shipboard deployment of at least 90 days with a non-
operational aircraft, or a 50% or greater reduction to
a unit's aircraft inventory without a reduction in the
number of assigned crewmembers for a temporary period
of at least 90 days. The commanding officer must certify
that only the conditions under this paragraph prevent
completion of normal flight requirements. This authority
may not be delegated.
(b)
In such circumstances, the member may comply with
minimum flight requirements by performing 24 hours
of aerial flight over a period of six calendar months.
The 24-hour flight requirement may be met at any time
during the six-calendar-month period and in any combination
of flights.
(c)
If a member is in a "grace" period when military operations
or unavailability of aircraft prevents fulfillment of
flight requirements, the six-calendar-month period for
meeting the 24-hour flight requirement under paragraph
9.a. (5) (b) above begins on the first day of the "grace"
period.
(d)
If a member is not in a "grace" period, the first
month in which military operations or unavailability of
aircraft prevents fulfillment of flight requirements is
the beginning of the
