Narrative:

Eug is a complex level ii tower/TRACON (approaching level III traffic count). The tower controller has a BRITE scope. We have a diverse mix of traffic: acrs, atx, corp twins and jets, military and GA--including a community college flight school. We provide stage ii service, which is used by maybe 30-40% of our VFR departures. A frequency problem is VFR departures, particularly those who do not request stage ii, which: 1) fly out the departure course (IFR departures, many of them faster, are assigned runway heading), or worse, 2) fly out the arrival course--even at corresponding INS approach or visibility glide path altitudes. This creates unsafe conditions, and a significant workload drawing the time and attention from the tower controller who is already responsible for traffic pattern sequencing, runway sep (including crossing runways), IFR arrival and departure sep within 6-10 mi of the airport, and coordination--verbal, interphone and data block. Hourly airport operations counts commonly range from 40-80, and occasionally more. The latest occurrence for me was with runway 34 in use. A VFR small aircraft, negative stage ii, requested and was approved for a left downwind departure, during a period of moderate to heavy itinerant and local traffic (69 airport operations that hour). A short time later, an medium large transport X followed by an medium large transport Y, came on my frequency from approach control--both about 7 mi southeast on right base for a visibility approach. I observed a s-bnd 'V-tag' (1200 code) with unverified mode C readout indicating 3000', about 3-4 mi south of the airport on the final approach course. I issued traffic alert instructions 'advise you expedite descent through 2500'' to the medium large transport X, and in turn to the medium large transport Y, and also issued traffic, and instructions to alter course away from the final approach course to the small aircraft. Solutions are pilot education, and an arsa for eug.

Title: CTLR NOT SATISFIED WITH CURRENT ATC SERVICES AT HIS ARPT.

Narrative: EUG IS A COMPLEX LEVEL II TWR/TRACON (APCHING LEVEL III TFC COUNT). THE TWR CTLR HAS A BRITE SCOPE. WE HAVE A DIVERSE MIX OF TFC: ACRS, ATX, CORP TWINS AND JETS, MIL AND GA--INCLUDING A COMMUNITY COLLEGE FLT SCHOOL. WE PROVIDE STAGE II SVC, WHICH IS USED BY MAYBE 30-40% OF OUR VFR DEPS. A FREQ PROB IS VFR DEPS, PARTICULARLY THOSE WHO DO NOT REQUEST STAGE II, WHICH: 1) FLY OUT THE DEP COURSE (IFR DEPS, MANY OF THEM FASTER, ARE ASSIGNED RWY HDG), OR WORSE, 2) FLY OUT THE ARR COURSE--EVEN AT CORRESPONDING INS APCH OR VIS GLIDE PATH ALTS. THIS CREATES UNSAFE CONDITIONS, AND A SIGNIFICANT WORKLOAD DRAWING THE TIME AND ATTN FROM THE TWR CTLR WHO IS ALREADY RESPONSIBLE FOR TFC PATTERN SEQUENCING, RWY SEP (INCLUDING XING RWYS), IFR ARR AND DEP SEP WITHIN 6-10 MI OF THE ARPT, AND COORD--VERBAL, INTERPHONE AND DATA BLOCK. HOURLY ARPT OPS COUNTS COMMONLY RANGE FROM 40-80, AND OCCASIONALLY MORE. THE LATEST OCCURRENCE FOR ME WAS WITH RWY 34 IN USE. A VFR SMA, NEGATIVE STAGE II, REQUESTED AND WAS APPROVED FOR A LEFT DOWNWIND DEP, DURING A PERIOD OF MODERATE TO HVY ITINERANT AND LCL TFC (69 ARPT OPS THAT HR). A SHORT TIME LATER, AN MLG X FOLLOWED BY AN MLG Y, CAME ON MY FREQ FROM APCH CTL--BOTH ABOUT 7 MI SE ON RIGHT BASE FOR A VIS APCH. I OBSERVED A S-BND 'V-TAG' (1200 CODE) WITH UNVERIFIED MODE C READOUT INDICATING 3000', ABOUT 3-4 MI S OF THE ARPT ON THE FINAL APCH COURSE. I ISSUED TFC ALERT INSTRUCTIONS 'ADVISE YOU EXPEDITE DSNT THROUGH 2500'' TO THE MLG X, AND IN TURN TO THE MLG Y, AND ALSO ISSUED TFC, AND INSTRUCTIONS TO ALTER COURSE AWAY FROM THE FINAL APCH COURSE TO THE SMA. SOLUTIONS ARE PLT EDUCATION, AND AN ARSA FOR EUG.
