According to statistics, up to 66% of serious accidents occur during takeoff and landing. However, current air traffic control systems are primarily designed to track aircraft after they are on course. ALTACAS aims to fill this gap.
The complex was developed by ALTACAS Technology and complements the existing air traffic control system in order to prevent accidents on the runway. It is proposed to control everything that happens on it with the help of lasers and microprocessors.
Moreover, the planes themselves control the runway. ALTACAS prevents aircraft collisions by tracking aircraft on a collision course. When a dangerous situation arises, the system warns both the crew and the ground control point.
One of the main elements of the system is the MRAH multidirectional radar mounted on the wings or fuselage. It consists of a rotating hemispherical body containing lidars - laser rangefinders, sensors and receivers.
The second part of the system is represented by the CAPU control and data processing unit, which consists of a central processor and a control display in the cockpit. It is connected to the remote processor of the aerodrome traffic control system.
During operation, the ALTACAS system informs the pilot about the take-off weight, aircraft speed and wind speed. The system then starts scanning the strip and the area above it. When another aircraft or ground object appears in the field of view, ALTACAS analyzes the situation and, in case of danger, issues a warning.
