Human Factors; Procedure
A C650 was cleared for a visual approach to Runway 18R and instructed to intercept final on a 150 heading due to traffic going to the parallel. A BE1900 was cleared visual approach to 18L and instructed to intercept final on a 210 heading due to traffic going to the parallel. The C650 flew through his own final and directly in front of the BE1900. The C650 did not follow instructions and caused an unsafe situation to occur with another aircraft. The FAA implemented the 30 degree intercept rule for aircraft on a visual approach to parallel runways to prevent aircraft from overshooting their final and possibly hitting another aircraft. The problem is that the pilots that I talked with had no idea what to do when given the instruction. They had not been briefed on the new approach clearance phraseology and were therefore caught by surprise. My advise is to brief the pilots to such a change.
TUL Controller described an unsafe event during side visual approaches to parallel runways when traffic failed to follow the thirty degree intercept instruction; causing a conflict.
