Near collision of 2 planes in Hawaii investigated

By Star-Advertiser staff

LAST UPDATED: 11:50 a.m. HST, May 16, 2014

Federal Aviation Administration and National Transportation Safety Board personnel arrived in Honolulu on Thursday to investigate a near midair collision involving two commercial jetliners.

On April 25 an eastbound United Airlines Boeing 757 received an automated alert to avoid a westbound US Airways Boeing 757 about 200 miles northeast of Kona, the FAA said.

The planes were separated by eight miles laterally when the United crew responded to the Traffic Alert and Collision Avoidance System. On the next radar update 12 seconds later, the planes were separated by 5.3 miles laterally and 800 feet vertically, which was as close as they got to each other, according to preliminary radar data.

The required separation in that airspace is either five miles laterally or 1,000 feet vertically, according to the FAA.

Interesting story. The author seem to be a of a drama queen in his writing.

I found it hard to believe that the flight crew would be so forthcoming with all the stuff he said they told him.

"The required separation in that airspace is either five miles laterally or 1,000 feet vertically." And, the closest approach was 5.3 miles laterally--more than required--so why is this a news story?

Probably because if both aircraft continued on their vectors, the next 12 sec. radar sweep would show that the aircraft would be in violation of the lateral separation (e.g. first radar sweep: 8 mi. lateral separation, second radar sweep (12 sec. later): 5.3 mi. lateral separation, third radar sweep (another 12 sec. later): lateral separation violation -- 2.6 mi. lateral separation, potentially).
