Organising flights in a multisquad campaign.

Other question, which mile the RAF use
1.609,3426m = 1mile?

At the moment i generate messages like
6 Enemy in Sector: A,3 heading 180
7906m 350° from Smalltown
but i will
7 miles North from Smaltown (Smalltown only a example, i added Landmarks to the script).
but i wanna know the compass terms like N, NE, E, SE, S, SW, W, NW are enough or are more needed NNW, NNE, etc? And the heading was it geografical or magnetic?

[bolox]

correct- RAF used 'English' miles upto Sept '45 when they converted to Nautical miles (knots), involving the change of every asi

AFAIK headings were usually given as 'vectors' in degrees (10 deg increments)
I THINK this was magnetic.
(there was a second format using 'bearing' and iirc this used the other North, however i may be mixing the 2 up)
need to find reference to this

Ok new version to test:
Added Landmarks to the mission, now you get messages like
27 Enemy 15 miles West from Calais at Angels 13, Heading 320
18 Enemy 13 miles South East from New Romney at Angels 8, Heading 0
in the chatbar

To do:
-Add more 'fuzzy' to the messages but at moment i don't know how exact the british radar was.
-merge the Airgroups better if they are in 'pulks'.

I've read something of a 300% inaccuracy but that sounds grossly overstated to me. I do have a suggestion, however, and that pertains to the reported number of planes. IIRC the numbers were never that accurate, mostly it was 10+ or 20+ ... so I wonder if it would be better to use this term (which also adds a bit of insecurity as 10+ can mean 10 or 19) ...

It could give heading when 2 or more plots were registered. It could easily tell who was friend or foe from the signal and FC (as part of the 4 minute delay) would be able to give an interception vector. You are correct on the aircraft numbers, and this could be implemented with a switch statement in code.

No switch statement needed a simple Math.Round will do the job too and better
So how the numbers of aircraft was given

1, 2, 5+ 10+ 15+ 20+ etc?

[5./JG27.Farber]

Bravo Kodiak! This is a real work of art!

Single or few aircraft were hard to detect I belive. Think it would be more:

5+, 10+ 20+ 30+


How did you find the location for each town? Place a static in each town and look in the .mis file?

From what I've read about the Chain Home radar, the altitude was measured comparing the strength of two receivers at different heights in the tower. Because of this, they where measuring angles.

Since the angles where not exact, the altitude error increased with the distance. I think this could be emulated with simple trigonometry using random errors for the angle.

[5./JG27.Farber]

Is this the final evolution of the script Kodiak? We are eger to implement it and iron out the wrinkles on our own maps. What about the 4 min delay?

Thanks for this,
Farber.
