Sea dye works best when the sea is reasonably calm. If the sea is rough
it is difficult to sea because it gets broken up by wave action and also
there is less colour contrast.

Having been involved in many over water searches for downed aircraft I
have
found that civilian pilots are not properly equipped as a general rule.
If
it is not on your person when you go down you may be "SOL". Having
found a
UH-1H that went down, the one thing that remained in the area and was
the
easiest to spot from 500AGL was sea dye. It was amazing how easy it was
to
find the military survivors when they used dye. It was a green dye and
spread out and covered an area almost the size of a football (US) field
in a
matter of 20 minutes after they went down. Once I found the dye it then
still took a minute or so to locate the crew in their 10 man raft. Much
easier to see the dye than the raft, but the dye is what lead me to
them.
BTW Sun N Fun was great

Thats why I raised the point about using smoke or sea dye. I know
nothing
whatsoever about ELT technology but I figured it would only give a
general
location as to where the ELT is located - ie it isnt direction
sensitive. My
guess an ELT will only guide the search helicopter or vessel to within a
mile or two of the target and then its down to the Mk1 eyeball.
Assuming there is time to make a mayday call that alone should be
sufficient
to guide search and rescue to within a couple of miles but there is no
guarantee you could make that call in an emergency or accurately give
your
location - I must see if there is a button on my Garmin which will
display
the GPS coordinates.
Smoke or dye makes it much quicker to locate a downed craft as there may
well be other small vessels in the search area and the SAR would need to
elimnate these as possible targets.
As to immersion suits I am not sure these are any lighter than carrying
a
raft (Transair sells a raft which is 12kg) - maybe someone makes a
lightweight version. I personally feel that a bulky survival suit would
be
somewhat impractical for flying. Purely from a weight point of view a
diving
wet suit would afford a considerable improvement in survivability.
