The Runway Awareness and Advisory System (RAAS) is an electronic detection system that notifies aircraft flight crews on the ground of their position relative to their allocated runway. It is a type of Runway Situation Awareness Tool (RSAT).
Descent of the airplane to 500 feet above the terrain or nearest runway elevation (voice callout "Five Hundred") during a non-precision approach. Optional: Class B TAWS installation may provide a terrain awareness display that shows either the surrounding terrain or obstacles relative to the airplane, or both.
Warning time can also be short if the aircraft is flying into steep terrain since the downward-looking radio altimeter is the primary sensor used for the warning calculation. The EGPWS improves terrain awareness and warning times by introducing the Terrain Display and the Terrain Data Base Look Ahead protection. [citation needed]
Runway safety is concerned with reducing harm that could occur on an aircraft runway. Safety means avoiding incorrect presence of aircraft, inappropriate exits and use of the wrong runway due to confusion. The runway condition is a runway's current status due to meteorological conditions and air safety. [1]
Once installed, the Surface Awareness Initiative works by using aircraft-broadcasted data to display surface traffic to controllers at airports without a surface surveillance tool — like Austin ...
The Airport Movement Area Safety System (AMASS) visually and aurally prompts tower controllers to respond to situations which potentially compromise safety. AMASS is an add-on enhancement to the host Airport Surface Detection Equipment Model 3 (ASDE-3) radar that provides automated aural alerts to potential runway incursions and other hazards.
DOWNERS GROVE, lll. — Imagine being able to pull a plane out of your garage door, drive down your driveway and take off on a trip. No driving to the airport. No security lines. No waiting at all.
The view of a runway from Honeywell's SmartRunway. Honeywell's Runway Awareness and Advisory System (RAAS) was first approved by the FAA in 2004. [43] The basic RAAS system issues audible alerts based on an aircraft's position on the ground in respect to runways.
