Yikes, 3000 m doesn't give you much time! How good are you at estimating AOB by eye? If you can get adept at doing that, which doesn't take long, you can still use the Auswanderungsverfahren and time his bearing change over one minute as in the tutorial. Just remember that the larger the AOB, the less prone to error the Auswanderungsverfahren is. So my suggestion would be to maneuver in from the side so that the target is approaching you at what appears to be a relatively large (Say 60-70°) AOB and begin your timing from there, maybe from a range of 1500 m or so so that AOB is easily estimable.
As far as estimating AOB from long distances in your case, the only thing I can think of is that the 3-bearing AOB Finder wheel (not to be confused with the RAOBF) made by Pisces I believe, which is included in the MAGUI GUI. With this, you take three bearings to the target at equal time intervals while stopped at long-distance and with this wheel you can derive target AOB from the last bearing you took (I think that's how it works).
Hopefully this helps!
