Narrative:
While working local control 2 (east; runway 35R) with heavy traffic and numerous departures; our radar failed. This has been a constant problem now at gfk. Targets will disappear from the scope for 2-3 sweeps; during moderate to heavy traffic the radar system cannot distinguish targets and a '?' will appear for each target; and the user interface is very frustrating (ie; entering flight plans; and other basic radar functions). With gfk averaging 1200-1600+ operations a day now; and numerous foreign student pilots flying around; having a radar we can rely on is essential for the safe and efficient movement of traffic here. With the talk of another 30-40 aircraft arriving soon to accommodate the increased foreign student pilots and another 5-10 helicopters; we need a reliable radar as soon as possible.
Original NASA ASRS Text
Title: GFK TWR CTLR EXPRESSED CONCERN REGARDING CONTINUED INCREASED TFC AND CONSTANT RADAR FAILURES.
Narrative: WHILE WORKING LCL CTL 2 (E; RWY 35R) WITH HVY TFC AND NUMEROUS DEPS; OUR RADAR FAILED. THIS HAS BEEN A CONSTANT PROB NOW AT GFK. TARGETS WILL DISAPPEAR FROM THE SCOPE FOR 2-3 SWEEPS; DURING MODERATE TO HVY TFC THE RADAR SYS CANNOT DISTINGUISH TARGETS AND A '?' WILL APPEAR FOR EACH TARGET; AND THE USER INTERFACE IS VERY FRUSTRATING (IE; ENTERING FLT PLANS; AND OTHER BASIC RADAR FUNCTIONS). WITH GFK AVERAGING 1200-1600+ OPS A DAY NOW; AND NUMEROUS FOREIGN STUDENT PLTS FLYING AROUND; HAVING A RADAR WE CAN RELY ON IS ESSENTIAL FOR THE SAFE AND EFFICIENT MOVEMENT OF TFC HERE. WITH THE TALK OF ANOTHER 30-40 ACFT ARRIVING SOON TO ACCOMMODATE THE INCREASED FOREIGN STUDENT PLTS AND ANOTHER 5-10 HELIS; WE NEED A RELIABLE RADAR ASAP.
