F.1.b.  Signal Flags
 Signal flags are another effective method of signaling to an assisting aircraft.  (see Figure 6-3)

F.2.  Signal Fires or Smoke
 Signal fires or smoke coming from a surface vessel may be from burning oil or oily rags in a can and can be detected from a considerable distance.  (see Figure 6-4)

F.3.  Pyrotechnic Signals
 Pyrotechnics include flares and meteors from the surface as well as smoke.  (see Figure 6-5)  Pyrotechnic signals are used as both day and night visual aids along with handheld or floating smoke signals, used in daytime.  These emit a large volume of bright orange smoke that remains visible for several minutes.  Under high wind conditions, the smoke will dissipate rapidly making the signal less effective.  Handheld flares, although better at night, may also be used as daytime signals.  Coast Guard- or SOLAS-approved marine-type flares are much brighter than the old fuse type and are therefore much more visible from an aircraft.

F.4.  Dye Markers
 Dye markers appear on the water and may be any color.  (see Figure 6-6)

F.5.  Air-to-Surface Signals
 Another need for visual communication may arise when the aircraft has the need to direct a surface vessel.  This may occur when the aircraft is attempting to guide a surface vessel away from danger or towards another vessel to assist.  The Coast Guard and the Coast Guard Auxiliary have been providing copies of Coast Guard Form CG-3488 to boat operators for many years.  Thus, Auxiliarists can be expected to understand the maneuvers, and many members of the boating public will recognize them.  In any event, they will probably be understood even if the surface vessel crew has not been exposed to this form although repetition may be necessary.  (see Appendix A)
