Serious Runway Incursions Down at U.S. Airports

According to Federal Aviation Administration (FAA) statistics, the number of serious runway invasions at the US airport has sharply declined in the past 20 years, but it continues to increase since 2013.

According to the US Federal Aviation Administration and International Civil Aviation Organization, regardless of whether or not you are on another aircraft with entrance into the runway, takeoff, or the right to board a taxi, the invasion into the runway will be on the runway It means unauthorized existence. Potential conflict

There are 4 kinds of invasions, of which A and B are the most serious. The US Federal Aviation Administration defines class A intrusion as a serious accident where collisions are greatly avoided. Class B is defined as an accident with reduced separation and a high probability of collision, which can result in a time critical correction / avoidance response to avoid collisions.

In FY 2000, there were 67 invasions of Class A and Class B as of September 30, 2000, 43 of which were commercial aircraft. In fiscal 2010, the number of intrusions of Class A and Class B decreased to 6, three of which were related to commercial aircraft. Since that time, the number of invasions of A and B in 1 year has increased from 11 in 2013 to 19 in fiscal 2016, which has increased over the previous three years in the past three years. As of August 7, there were six invasions of A and B in FY 2017, two of which were due to commercial aircraft. The US Federal Aviation Administration stated that most of the intrusions belong to Class C and Class D and there is no danger of conflict.

Reducing the safety risk of the runway is a top priority for the FAA and one way the organization is studying this problem is designed to improve awareness of the crew and the driver of the airport It is the development of the runway condition light (RWSL) technology. . As an additional layer of security. RWSL currently operates in 11 major US airports, including Los Angeles International Airport, Washington Dulles Airport, George Bush Intercontinental Airport (Houston Airport), Orlando International Airport. The Federal Aviation Administration of the United States has received nine airports from the Chicago O'Hare International Airport, Dallas / Fort Worth International Airport, and JFK International Airport in New York at the various stages of local acceptance testing, construction or implementation, and until the end of the year We should arrive at. Start driving. September 30, 2017

According to the US Federal Aviation Administration, the RWSL system acquires traffic information from the ground and entry monitoring system and lights the red paved airport light to indicate a potentially dangerous situation. The entrance light of the runway is located at the intersection of the guideway and the runway and lights up when entry or crossing into the runway is not safe. If the aircraft is in takeoff position and the runway is occupied by other aircraft or vehicles and takeoff is dangerous, the takeoff light will turn red.

The US Federal Aviation Administration publishes an annual report on runway safety issues on FAA's website. A new system designed to improve the safety of the runway like the Airport Sports Area Security System (AMASS) and Runway Consciousness Advisory System (RAAS) is described in the report. When the runway of San Francisco International Airport was invaded in 2007, AMASS hardly prevented conflict.

Today, the US Federal Aviation Administration is working on reducing runway penetration by tracking and identifying aircraft and other vehicles passing through the airport. The US Federal Aviation Administration is working hard on the implementation of the Airport Sports Area Security System (AMASS) software. Due to the frequency of software errors and alarms, it is several years behind. For this reason, FAA wishes to use GPS navigation technology to create a surface display technology that provides portable map display and electronic mobile head-up display. This technology is developed by NASA's Langley Research Center in Hampton, Virginia. Steve Zaidman, who is responsible for research and development at the Federal Aviation Administration, says: "They reminded air traffic controllers of the possibility of collision and gave reaction time of about 20 seconds" (Trimble, p. 13)
