Narrative:
While the E145 was on a 5 mi final to runway 15 at bdl; the B757 was cleared for takeoff on runway 24. The B757 was a bit slow taking the runway and was prompted to begin takeoff roll while the E145 was on a 2 mi final. While working this runway confign there have been several false asde-X safety logic alerts to send the runway 15 arrival around after the departure had cleared the runway intersection. When the E145 was on a 1 1/2 mi final the 'helicopter' patch was used to avoid the asde-X from alarming. The B757 rotated beyond the runway intersection while the E145 was less than a 1 mi final. No separation was lost. The event was reported via a quality assurance review (qar) and via controller statement. The cause of the situation was the slow departure roll of the B757 and poor judgement was used by using the helicopter patch. The operation; while separation existed; was felt to be made unsafe if the E145 would have been sent around.

Title: BDL CONTROLLER DESCRIBED NEAR CONFLICT BETWEEN ARRIVAL ON RUNWAY 15 AND A DEPARTURE FROM RUNWAY 24; ALLEGING AN ISSUED GO AROUND WOULD HAVE COMPRISED SAFETY.
Narrative: WHILE THE E145 WAS ON A 5 MI FINAL TO RWY 15 AT BDL; THE B757 WAS CLRED FOR TKOF ON RWY 24. THE B757 WAS A BIT SLOW TAKING THE RWY AND WAS PROMPTED TO BEGIN TKOF ROLL WHILE THE E145 WAS ON A 2 MI FINAL. WHILE WORKING THIS RWY CONFIGN THERE HAVE BEEN SEVERAL FALSE ASDE-X SAFETY LOGIC ALERTS TO SEND THE RWY 15 ARR AROUND AFTER THE DEP HAD CLRED THE RWY INTXN. WHEN THE E145 WAS ON A 1 1/2 MI FINAL THE 'HELI' PATCH WAS USED TO AVOID THE ASDE-X FROM ALARMING. THE B757 ROTATED BEYOND THE RWY INTXN WHILE THE E145 WAS LESS THAN A 1 MI FINAL. NO SEPARATION WAS LOST. THE EVENT WAS RPTED VIA A QUALITY ASSURANCE REVIEW (QAR) AND VIA CTLR STATEMENT. THE CAUSE OF THE SITUATION WAS THE SLOW DEP ROLL OF THE B757 AND POOR JUDGEMENT WAS USED BY USING THE HELI PATCH. THE OP; WHILE SEPARATION EXISTED; WAS FELT TO BE MADE UNSAFE IF THE E145 WOULD HAVE BEEN SENT AROUND.
