VOLUME I Multinational Maritime Tactical Instructions and Procedures

6515 NOT RELEASABLE
6516 MANEUVERING FOR LOW VISIBILITY RECOVERY OPERATIONS
If, while aircraft are airborne, it appears likely that the task force will encounter fog, snow, or other
conditions of low visibility, the OTC may order the task groups to separate and proceed independently in
the direction of the best predicted or known clear weather. Airborne aircraft are to be advised of this action,
and they are to advise the OTC of any clear areas known to them.
6517 COURSE AND RELATIVE WIND
Normally, the course for launching and recovering fixed-wing aircraft will be such that the ship
concerned has the relative wind down the angled deck.
6518 OPERATIONS AT NIGHT
a. Lighting Measures. The OTC will order the degree of lighting to be used for night flying
operations. When lighting measures are ordered, ships shall automatically be darkened (except for the
lights prescribed by the lighting measure) without further signal unless otherwise ordered by the OTC.
Lighting measures are given in detail in Table 6-10. Lighting measure green is the minimum for all normal
night operations, even for specially trained pilots, and compelling reasons should exist for selecting a
lesser amount of lighting.
b. Flashing Light Communications. Except for signals concerning immediate flight
operations or emergency signals, unshielded or omnidirectional flashing light communications shall cease
15 minutes prior to scheduled night air operations and shall not be resumed until ships have signalled
completion of flight operations. Infrared light may be used for intership communications.
6519 OPERATIONS IN LOW VISIBILITY
The tactical situation may require shipborne aircraft to be launched and landed under low visibility
conditions. Governing considerations are the extent and severity of the weather conditions, the ability and
qualifications of the pilots, and the equipment to be used. Adequate preparations can be made when it has
been determined in advance that aircraft are to be launched and landed under known low visibility
conditions. It is also necessary that standard procedures be established for use when aircraft must operate
unexpectedly in unfavorable weather. When low visibility conditions are encountered or appear imminent,
an early decision must be reached as to how airborne aircraft are to be handled. One or more of the
following procedures may be used depending on existing conditions.
a. Aircraft orbit as directed until own ship has steamed into an area where visually controlled
landings can be made.
b. Aircraft land ashore in friendly territory if conditions permit.
c. Aircraft land on other appropriate ships which are operating in an area where visually controlled
landing can be made.
