Narrative:

Departing stl on IFR flight plan to sgf, ZKC cleared us to climb to FL180. Shortly after that, I noticed a target on our TCASII closing on us. By the time I was able to assess, he was at FL180 or about (actually 17500 ft). He was 8 mi away. I asked ATC if they had a target at our 2 O'clock and 8 mi. They said 'yes, he is at 17500 ft.' at about this time, the target entered our 2 mi range on TCASII and we got an RA at about 17000 ft and leveled off. I saw the aircraft go by when it was at the 2:30 O'clock position. I told ATC that it was very close to us and they replied, '...17500 ft is a VFR altitude....' there were other human factors involved in this such as: training (ATC), high volume, complexity of situation (arrs to stl just were shut off) and a death in trainer's family. The management agreed with me that traffic should have been issued, but not required since other aircraft were VFR and not talking to anybody! With the increase of regional jets and other traffic, forcing executive and 'fractionals' jets to go VFR below FL180, I see a big problem arising. Something needs to be done about traffic at VFR altitudes!

Title: MD80 FLC INITIATES EVASIVE MANEUVER DUE TO TCASII RA WHEN ZKC DOES NOT ISSUE TFC ALERT.

Narrative: DEPARTING STL ON IFR FLT PLAN TO SGF, ZKC CLRED US TO CLB TO FL180. SHORTLY AFTER THAT, I NOTICED A TARGET ON OUR TCASII CLOSING ON US. BY THE TIME I WAS ABLE TO ASSESS, HE WAS AT FL180 OR ABOUT (ACTUALLY 17500 FT). HE WAS 8 MI AWAY. I ASKED ATC IF THEY HAD A TARGET AT OUR 2 O'CLOCK AND 8 MI. THEY SAID 'YES, HE IS AT 17500 FT.' AT ABOUT THIS TIME, THE TARGET ENTERED OUR 2 MI RANGE ON TCASII AND WE GOT AN RA AT ABOUT 17000 FT AND LEVELED OFF. I SAW THE ACFT GO BY WHEN IT WAS AT THE 2:30 O'CLOCK POS. I TOLD ATC THAT IT WAS VERY CLOSE TO US AND THEY REPLIED, '...17500 FT IS A VFR ALT....' THERE WERE OTHER HUMAN FACTORS INVOLVED IN THIS SUCH AS: TRAINING (ATC), HIGH VOLUME, COMPLEXITY OF SIT (ARRS TO STL JUST WERE SHUT OFF) AND A DEATH IN TRAINER'S FAMILY. THE MGMNT AGREED WITH ME THAT TFC SHOULD HAVE BEEN ISSUED, BUT NOT REQUIRED SINCE OTHER ACFT WERE VFR AND NOT TALKING TO ANYBODY! WITH THE INCREASE OF REGIONAL JETS AND OTHER TFC, FORCING EXECUTIVE AND 'FRACTIONALS' JETS TO GO VFR BELOW FL180, I SEE A BIG PROB ARISING. SOMETHING NEEDS TO BE DONE ABOUT TFC AT VFR ALTS!
