Narrative:

Aircraft requesting a user drawn 'NDB' type approach cause frequency congestion and a near midair collision hazard within the air traffic area at prescott, az. Contributing factors: the users have drawn the approach to a minimum altitude 500' below the pattern altitude. This necessitates the controllers to take valuable frequency time to instruct almost every aircraft to maintain at or above some altitude. Corrective actions: redraw the user provided approach to provide a missed approach altitude well above the pattern altitude at love field, prescott, az. This will eliminate a lot of frequency congestion. And greatly decrease controller workload.

Title: CTLR REPORTER PROTESTS INDIVIDUALLY DRAWN TRAFFIC ENTRY PATTERNS THAT CONFLICT WITH PRC ARPT TRAFFIC PATTERN.

Narrative: ACFT REQUESTING A USER DRAWN 'NDB' TYPE APCH CAUSE FREQ CONGESTION AND A NEAR MIDAIR COLLISION HAZARD WITHIN THE ATA AT PRESCOTT, AZ. CONTRIBUTING FACTORS: THE USERS HAVE DRAWN THE APCH TO A MINIMUM ALT 500' BELOW THE PATTERN ALT. THIS NECESSITATES THE CTLRS TO TAKE VALUABLE FREQ TIME TO INSTRUCT ALMOST EVERY ACFT TO MAINTAIN AT OR ABOVE SOME ALT. CORRECTIVE ACTIONS: REDRAW THE USER PROVIDED APCH TO PROVIDE A MISSED APCH ALT WELL ABOVE THE PATTERN ALT AT LOVE FIELD, PRESCOTT, AZ. THIS WILL ELIMINATE A LOT OF FREQ CONGESTION. AND GREATLY DECREASE CTLR WORKLOAD.
