Narrative:

TCASII RA conflict is an almost foregone conclusion when departing phx on the eagul 3 SID off runway 8L/right using normal noise abatement procedures -- if there are any VFR aircraft just east of the class B airspace at 3000 ft as was our case. VFR aircraft was under ATC radar flight following at 3000 ft approximately 6 mi east of pxr VOR. The eagul 3 SID restricts you to 'at or below 3000 ft' crossing VOR. You continue climbing east (075 degree radial) to the 4 DME then turn north (020 degrees). Typical departure -- hot, heavy and using noise abatement procedure thrust settings -- you barely meet minimum climb gradient (350 ft per NM). If VFR aircraft is just outside class B as you start your turn at 4 DME you are sure to get a TCASII RA. Either change the airspace, change the SID, or forget noise abatement climb.

Title: RPTR STATED FLT GOT A TCASII RA WITH VFR TFC OPERATING OUTSIDE THE CLASS B WHILE CLBING ON THE SID.

Narrative: TCASII RA CONFLICT IS AN ALMOST FOREGONE CONCLUSION WHEN DEPARTING PHX ON THE EAGUL 3 SID OFF RWY 8L/R USING NORMAL NOISE ABATEMENT PROCS -- IF THERE ARE ANY VFR ACFT JUST E OF THE CLASS B AIRSPACE AT 3000 FT AS WAS OUR CASE. VFR ACFT WAS UNDER ATC RADAR FLT FOLLOWING AT 3000 FT APPROX 6 MI E OF PXR VOR. THE EAGUL 3 SID RESTRICTS YOU TO 'AT OR BELOW 3000 FT' XING VOR. YOU CONTINUE CLBING E (075 DEG RADIAL) TO THE 4 DME THEN TURN N (020 DEGS). TYPICAL DEP -- HOT, HVY AND USING NOISE ABATEMENT PROC THRUST SETTINGS -- YOU BARELY MEET MINIMUM CLB GRADIENT (350 FT PER NM). IF VFR ACFT IS JUST OUTSIDE CLASS B AS YOU START YOUR TURN AT 4 DME YOU ARE SURE TO GET A TCASII RA. EITHER CHANGE THE AIRSPACE, CHANGE THE SID, OR FORGET NOISE ABATEMENT CLB.
