G'day List, Thought I would send another, Just a small one, but I have never seen it used by anyone but me. Helo sonobouy patrols within the formation. This probably comes under the heading of "Personal taste" but here goes. I will set Helo 1 to a zone about 1/2 mile wide and from the 28 mile ring out to the 33 mile ring. This lays bouys along the PIM. I will set Helo's 2 and 3, left and right of this one. Their zones are set along the 32 mile range ring, and also 1/2 a mile wide. These zones begin about 2-3 mile from H1's line and stretch 2-4 mile in a concentric circle arc. This forms a "T" shape. I will then set helo's 4 and 5 at 45 degrees left and right of the PIM, and set a zone for these similar to Helo 1, a 5 mile long, 1/2 mile wide stretching from 28 mile to 33 again. This will cause the helos to lay a "Chevron" pattern. I will repeat this pattern all round the fleet. LR ASW assets (Vikings, ..etc) out to cz2 If I have em, using similar patterns. This seems to give good coverage, But I will listen to anything better. :) God invented alcohol so that the Australians would not rule the world. Best Regards Michael C. Deegan FOUR_KIDS@bigpond.com
