Description
Superior, automatic, clutter-free weather detection and analysis out to 320 nm.
Collins Aerospace MultiScan ThreatTrack™ weather radar offers an innovative approach to detecting and analyzing weather phenomena and displaying adverse weather threats, enabling safer, smoother and more efficient flights.
Global flight tests of the system have validated the performance of the threat detection concept and ensure that the radar makes optimum adjustments to maximize the "probability of detecting" thunderstorms during all phases of flight.
Crews will benefit from additional innovative technologies that go beyond today's most advanced radar systems by adding predictive weather analysis and new threat detection features.
MultiScan ThreatTrack™ features
- Patented track-while-scan technology prioritizes weather threats out to 320 nm by performing dedicated horizontal and vertical scans on developed or fast-growing convective cells that pose an actual threat.
- Core threat assessment examines thunderstorm cells and increases the displayed colors to better represent the actual thunderstorm threat.
- Associated threat assessment infers lightning, hail and convective threat potential within and external to a thunderstorm core.
- Predictive OverFlight™ protection tracks thunderstorm cells ahead and below the aircraft, measures growth rate, predicts bow-wave turbulence and indicates potential threats in the aircraft's flight path.
- Two-level enhanced turbulence detection detects severe and ride-quality turbulence up to 40 nm ahead of the aircraft.
- Predictive wind shear detection with wind shear event data recording and retrieval.
- Geographic weather correlation uses a database of geographic and seasonal weather variations that enhance MultiScan ThreatTrack's algorithms to provide accurate worldwide hazard information.
- Advanced ground clutter suppression eliminates ground clutter on the weather display at all ranges, allowing pilots to concentrate exclusively on true weather threats.
- Track-while-scan thunderstorm assessment out to 320 nm
- Core threat assessment increases display colors based on potential threat
- Associated threat assessment with inferred hail and lightning threats outside of the cell
- Predictive OverFlight protection tracks and alerts on rapidly building cells in the flight path
- Two-level enhanced turbulence detection - certified turbulence plus ride-quality turbulence displays
