4. Background
a. Development of effective new air weapon systems in the past has been highly sensitive to
human engineering factors. The unique demands of naval aviation and the multiplicity of
aviation programs have required the support of a limited officer inventory skilled concurrently in
the professional qualifications of a naval aviator and of a flight surgeon. To meet that
requirement, selected individuals trained as medical officers have been cross-trained as naval
aviators. Their assignments were selectively made to meet the identified requirements of billets
or projects and programs requiring the skills of both disciplines in a single individual. The
billets predominated in, but were not limited to, Navy research and development (R&D)
activities. The number and complexity of emerging weapons systems have required dual
designation of a naval aviator and flight surgeon Medical Corps in the past. An improved
understanding of the roles and capabilities of dually-designated, aero-medically trained officers
has now led to the more precise codification of the dual designator program, with the inclusion
of naval flight officers (NFO), as well as aerospace physiologists, aerospace experimental
psychologists, aerospace physician assistants, and aerospace optometrists.
