The U.S. Air Force's F-16D Ground Collision Avoidance Technology (GCAT) aircraft. An airborne collision avoidance system (ACAS, usually pronounced as ay-kas) operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collision.
In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. [3]
In the US 49/563.5 regulatory framework, Event data recorder is defined as a . a device or function in a vehicle that records the vehicle's dynamic time-series data during the time period just prior to a crash event (e.g., vehicle speed vs. time) or during a crash event (e.g., delta-V vs. time), intended for retrieval after the crash event.
Modern weather systems also include wind shear and turbulence detection and terrain and traffic warning systems. [12] In‑plane weather avionics are especially popular in Africa, India, and other countries where air-travel is a growing market, but ground support is not as well developed. [13]
A police van and an ambulance in Thuringia, Germany in 2013. An emergency vehicle is a vehicle used by emergency services.Emergency vehicles typically have specialized emergency lighting and vehicle equipment that allow emergency services to reach calls for service in a timely manner, transport equipment and resources, or perform their tasks efficiently.
A fire truck uses an air horn to alert cars of its presence. Air horn - These devices force compressed air from the vehicle's air brake system against a diaphragm, creating a loud noise. Air horns used on emergency vehicles usually have a distinctive tone so they can easily be distinguished from other large vehicles, commanding urgency.
Newer devices can also act as authorized flight recorders by producing files in the IGC format defined by the FAI Gliding Commission. All FLARM devices can be connected to FLARM displays or compatible avionics (EFIS, moving map, etc.) to give visual and audio warnings and also to show the intruder's position on the map.
Examples include a digital electronic sign, a loud speaker that is part of a PA system, or a large flat panel display on a wall. A private communication device is a device that is designed to deliver a communication to one person at a time through a single process. Typically, a single person is in control of such a device which is usually not ...
