I've noticed lately that the dar-bar has been acting funny. Sometimes it won't show a con is in the sector even though they are well above the 200 foot NOE limit. It doesn't show a dar-bar for my plane (if memory serves it never did anyway), but I'll have a squaddie flying right next to me and he won't have a dar-bar either.
A good example is that today I was jumped by a spixteen shortly after taking off in a 262. The spit never registered a dar-bar for the sector and never showed up on radar (not sure if it was knocked out or not).
Just something I thought might need some looking into, was never really a problem until today.
I hope it's ok to quote Skuzzy!

This may help explain about dar bar. Here's what I was told in regards to airplanes entering sectors:
"The radar bar does not update in real time. It is a timed update. It will
depend on where you are in relation to the sector line and how long you were
in the sector, as well as how long the other player was in the sector.
Clipping a corner of a sector can result in not seeing the radar bar
trigger, or it can. It would depend on the last update time.
Lot of variables involved.
'Dar' bar is supposed to be 'iffy'. Not absolute. It is designed that way
so as to allow the potential for being surprised."
"Again, bar updates are not real time. When you got within visible view
range, your computer triggered the radar bar update to everyone. All he had
to do was be in the sector longer than you and he could have gotten an
update before you."
