Near-misses at Washington airport worried pilots well before fatal crash

U.S. commercial pilot Rick Redfern was preparing to land at Reagan Washington National Airport about a years back when he found a bright red Coast Guard helicopter hovering about 50 feet (15 m) above the Potomac River. Air traffic control service without delay cautioned the helicopter pilot to remain clear, and Redfern said he utilized evasive maneuvers to avoid it and avert a prospective disaster and that was in daytime, when visibility was clearer. During the night the light can disorient you as to what you might believe you are seeing as to what you in fact are seeing, Redfern stated. A collision on Wednesday night in between a Black Hawk military helicopter and an American Airlines subsidiary's CRJ700 regional jet, which eliminated 67 people, has stirred haunting memories for Redfern and other pilots who have faced obstacles landing at the Washington airport. Aircrafts approaching the airport should browse an accurate and narrow flight course to avoid restricted airspace around the close by White Home and Pentagon. That turn from the eastern side along the river to turn into runway 33 is extremely, very tight, said Redfern, describing the very same airstrip the American Airlines jet was heading towards before colliding with the U.S. military helicopter. It is uncertain what caused the crash, which is now under investigation by the U.S. National Transportation Security Board and the U.S. Army. Air crashes usually arise from several aspects. 7 U.S. pilots informed Reuters the landing at Reagan airport is distinct due to overloaded space, along with an inability to interact directly with military airplane, which run on various radio frequencies. The airport also has much shorter runways, consisting of runway 33, which is usually reserved for smaller airplane, among the 7 aviators said. For pilots, it means passing through narrow airspace, since planes can not cross the eastern shoreline of the Potomac River when approaching the airport that is also used frequently by the military for training, the aviators said. The U.S. Army Black Hawk helicopter involved in the crash was on a training flight and flying at an altitude of about 300 feet at the time of the crash, according to FlightRadar24 information. To avoid crashes with other aircraft, pilots count on the Traffic Alert and Accident Avoidance System, much better referred to as TCAS. When TCAS detects a dangerously close aircraft, it gives instructions to the pilots to prevent a collision, such as pull up or descend, turn left or turn right. However, when a plane is below about 1,100 feet, TCAS stops offering instructions to pilots. There just isn't enough space below that to steer, stated air travel safety specialist and previous airline company pilot John Nance. NEAR MISSES OUT ON

A Reuters review of events at Reagan airport including helicopters exposes pilots had actually been raising alarm about near-misses back to the 1980s. You certainly are bringing your A-game when you fly in and out of Reagan, stated former long-time commercial airline pilot Kathleen Bangs. Out of 46 incidents flagged anonymously by pilots in the Aviation Safety Reporting System database, 26 cases involved near-misses or recklessly close contact. In a report about an occurrence in September 1989, one pilot grumbled that military helicopters and business airplane are on different radio frequencies, can not hear each other and rely on extremely busy traffic controllers to prevent mishaps. The pilot grumbled it was his seventh near-miss with a. helicopter in 4-1/2 years flying into the airport. Is DCA (Reagan) an overloaded airspace? Yes, by far no doubt. about it, said Dennis Tajer, a representative for the Allied. Pilots Association that represents American Airlines. mainline pilots.

It remains in a really tight airspace because there are limited. locations all around the airport.

While constrained airspace makes the method more. challenging, air travel security experts have not raised extensive. concerns about the area constraints.

We have industrial flights and military flights and all. types of flights operating out of Reagan National every day,. said air travel safety and crash investigation professional Anthony. Brickhouse.

A PREVENTABLE DISASTER? In the moments before the crash, an air traffic controller can. be heard on recordings asking the Army helicopter to pass behind. the local jet.

They'll be studying what the helicopter pilots and. industrial pilots might have seen and any interaction in between. the two airplane, Brickhouse stated.

Business aircraft use Very High Frequency (VHF) radios to. communicate, while military airplane operate on Ultra High. Frequency (UHF) channels, making direct communication in between. them tough. However, the control tower can interact with. both frequencies. There are recognized procedures to different industrial and. military helicopter traffic, said the general aviation group. Aircraft Owners and Pilots Association (AOPA). Nonetheless, the accident might result in modifications. Army Secretary nominee Daniel Driscoll stated throughout a Senate. hearing on Thursday that the crash might prompt the military to. reevaluate conducting training operations near the busy. Washington, D.C., airspace.

This seems to be preventable, Driscoll said. I believe we. might need to look at where is a proper time to take. training risk, and it may not be near an airport like Reagan.
