Narrative:
It was a busy sunday afternoon, excellent WX resulting in lots of traffic and, no doubt, a high controller workload. ATIS specified winds from the northeast, departing runway 6, but several planes were requesting runway 15 and being approved. Small aircraft X was cleared for departure on runway 6. As I rolled onto the runway and began to accelerate, another aircraft was cleared to depart on runway 15, an intersecting runway. I called the tower to confirm that I had been cleared to takeoff and the controller said yes, that separation was fine. I could see the other plane, an small transport Y, crossing the intersection and lifting off to the southeast. I took off on runway 6 and climbed to 1000 ft. I saw small transport Y turning to the north. It proceeded to fly at 1000 ft on a collision course with me. I dove to avoid and notified the tower of what I considered to be a near miss. The frequency was congested, and it was several mins before I could get an acknowledgement. The controller answered, 'it's a VFR environment out there,' and suggested that I call the tower later.
Original NASA ASRS Text
Title: MULTIPLE RWY OP INTERSECTING RWYS SMA X HAD LTSS FROM SMT Y. SYS ERROR. SMA X HAD NMAC WITH SMT Y AFTER DEP. EVASIVE ACTION TAKEN. SEE AND AVOID CONCEPT.
Narrative: IT WAS A BUSY SUNDAY AFTERNOON, EXCELLENT WX RESULTING IN LOTS OF TFC AND, NO DOUBT, A HIGH CTLR WORKLOAD. ATIS SPECIFIED WINDS FROM THE NE, DEPARTING RWY 6, BUT SEVERAL PLANES WERE REQUESTING RWY 15 AND BEING APPROVED. SMA X WAS CLRED FOR DEP ON RWY 6. AS I ROLLED ONTO THE RWY AND BEGAN TO ACCELERATE, ANOTHER ACFT WAS CLRED TO DEPART ON RWY 15, AN INTERSECTING RWY. I CALLED THE TWR TO CONFIRM THAT I HAD BEEN CLRED TO TKOF AND THE CTLR SAID YES, THAT SEPARATION WAS FINE. I COULD SEE THE OTHER PLANE, AN SMT Y, XING THE INTXN AND LIFTING OFF TO THE SE. I TOOK OFF ON RWY 6 AND CLBED TO 1000 FT. I SAW SMT Y TURNING TO THE N. IT PROCEEDED TO FLY AT 1000 FT ON A COLLISION COURSE WITH ME. I DOVE TO AVOID AND NOTIFIED THE TWR OF WHAT I CONSIDERED TO BE A NEAR MISS. THE FREQ WAS CONGESTED, AND IT WAS SEVERAL MINS BEFORE I COULD GET AN ACKNOWLEDGEMENT. THE CTLR ANSWERED, 'IT'S A VFR ENVIRONMENT OUT THERE,' AND SUGGESTED THAT I CALL THE TWR LATER.
