COMMANDANT INSTRUCTION 3710.5A
Subj: AIRCRAFT EMPLOYMENT STANDARDS FOR DAYS DEPLOYED ABOARD
SHIP (DDAS) AND DAYS AWAY FROM HOME STATION (DAHS)
Ref: (a) Aeronautical Engineering Maintenance Management Manual, COMDTINST
M13020.1(series)
1. PURPOSE
. To provide guidelines for aircraft employment to operational commanders and
planning staffs. Enclosure (1) provides a derivation of the standards and definitions of the
terms used. Enclosure (2) lists the standards as they are applied to each Air Station. Enclosure
(3) gives examples of how the standards are applied to various situations.
2. ACTION
. Area, district, and unit commanders shall be guided by this Instruction in all matters
relating to aircraft facilities including planning, management, and evaluation. Nonetheless,
commanders responsible for aircraft schedules and deployments may authorize deviations from
Aircraft Employment Standards as required by specific operational necessities. In these cases,
consideration must be given to maintaining unit mission capability and identifying funding
sources to defray increased deployment costs.
3. DIRECTIVES AFFECTED.
Aircraft Employment Standards, COMDTINST 3710.5 is
cancelled.
4. DISCUSSION.
a This revised Instruction promulgates employment standards that more accurately reflect unit
capability based on current resource levels. Establishing a standard for employment of
aviation assets enables those who manage aircraft to maximize use of this resource, within
the applicable guidelines, while relieving small units from excessive days deployed and
associated increased costs. It is important to note that when meeting this standard, training
and pre-deployment work-ups away from home station count equally against the standard
(DDAS or DAHS, according to the definitions in enclosure (1)).
