A few years ago, Cox said he was off at Boeing 737 at Orlando International Airport when his system warned him and his co -pilot. The pilot looked for another aircraft, but did not see anything. Later, TCA provided an emergency instruction “Mountain climbing”. Cox said they did and later saw a small aircraft under them. He said the collision would have been devastating.
After a series of collisions, the parliament demanded the TCA on all large commercial aircraft on all large commercial aircraft from all large commercial aircraft in 1986 in a passenger car near CRASH and small aircraft CRASH. I instructed me. However, it is an option on military aircraft, and it is not clear that the Army helicopter involved in the crash drop on Wednesday is equipped.
However, although the crash occurred at a relatively low altitude, Cox and other safety experts said that TCAS's most important collision avoidance instructions were restricted by design. As the jet approaches the airport, they may approach each other than higher altitude. As a result, the system restricts problems to cause confusion and avoid safety.
Automatic dependency monitoring broadcast
In recent years, the FAA has demanded all passenger airlines and many other aircraft to use another system called Automatic Survival Broadcast. This technology broadcasts the location, altitude, speed, and other data installed every second. These broadcasts can be picked up by other aircraft and equipment on the ground.
Air Controls and many passenger aircraft pilots depend on the information received from the ADS-B system using devices that provide detailed maps of local aircraft. That information helps to visualize what is happening in the air, but the system does not usually issue alerts performed by TCAS. Still, ADS-B is useful for pilots. In particular, if you are flying under poor weather conditions, or when you have low visibility, Dr. Hassan Shahidi, president of non -profit Flight Safety Foundation.
