@pbrowne - Indeed!
@1nutworld - Wasn't a silly question at all.
Thanks, I try where I can.
Also for reference the detection levels:
detection level: 1 - generic category aircraft\helo|fixed-structure|runway|building|mobile-vehicle|mobile personnel|Carrier|
SurfaceCombatant|submarine|biologic etc basically their db category codes. Contact is labeled generic bogey\skunk\fixed\goblin etc.
detection level: 2 - type: for ships,subs and aircraft it's their DB entry type code (fighter|bomber|AEW|etc), facilities are more murky, and it's determined by a couple of factors like if mobile and has mounts then it can depend on the mount's mobileunitcategory, otherwise it's determined by what's contained in the db entries actual name +\- some other variable like if it has weapons on it, failing all that generic category is used. Contact will change name to the generic type prefix identified SAM,Surveillance,FFG,DDG,CG,CVN,Armor,SSM,AAA,SSGN,SSM,SSK,UUV,etc
detection level: 3 - class: actual dbid of unit name, contact will change name to the generic name of the unit.
detection level: 4 - precise: you know everything, contact name changes to actual unit name on it's side.
(btw not everything can neccessarly be level 4'd in my experience. for instance most mobile units can't be id'd above 3, where as runway components get id'd to level 4 almost instantly after 1 or 2 quality radar hits.). The exception to this is "autodetectable" which is automatic level 4.
Contact always keep their detection level (unless of course the contact just ages out or is manually dropped) even if track is lost.
Things like speed\heading\alt|depth\side while like are sensor capability specific and not exactly tied to detection level, ie you can know what side something is on and it's speed heading and alt without knowing exactly what it is yet - depends on the gear involved.
Hey man, that's a great breakdown on detection levels.
