I think itīs good to emphasize which signaling techniques you would use. If you list what you are carrying SAR people can figure something out but I still think itīs a good idea to write it out separately. For example:
"SIGNALING
acoustical signals:
whistle with high frequency tone (3x)
visual signals:
daytime:
3 smoke pillars
orange tarp
signal mirror flashes (3x)
big "V" or "SOS" on the ground built from available material
night time:
3 fires forming a triangle
flashlight flashes (3x, white color)"
etc.
