Honeywell EGPWS 69000940-101/ 69000941-101/ 69000942-151

The Honeywell EGPWS (Enhanced Ground Proximity Warning System) is a critical aviation safety system designed to prevent controlled flight into terrain (CFIT). It provides pilots with timely alerts and warnings about potential ground collisions, enhancing situational awareness and safety during flight.

• Terrain Awareness: Uses a global terrain database to provide real-time terrain mapping and alerts.
• Obstacle Database: Includes a comprehensive database of man-made obstacles (e.g., towers, buildings).
• Forward-Looking Terrain Avoidance (FLTA): Predicts potential terrain conflicts based on the aircraft's flight path.
• Excessive Descent Rate Alert: Warns pilots if the aircraft is descending too quickly.
• Altitude Callouts: Provides automated altitude callouts during approach and landing.
• Wind Shear Detection: Alerts pilots to dangerous wind shear conditions.
• Customizable Alerts: Configurable alerting modes for different phases of flight (e.g., takeoff, cruise, landing).
• Integration: Compatible with other avionics systems, such as flight management systems (FMS) and navigation displays.

The EGPWS combines GPS data, aircraft performance parameters (e.g., altitude, speed, heading), and a terrain/obstacle database to assess the aircraft's position relative to the ground. It provides visual and auditory warnings to the flight crew, such as:

• "Terrain Ahead, Pull Up"
• "Obstacle Ahead, Avoid"
• "Sink Rate"
• "Too Low, Terrain"

Enhanced Safety: Reduces the risk of CFIT, which is a leading cause of aviation accidents.

• Proactive Alerts: Provides early warnings, giving pilots time to take corrective action.
• Global Coverage: Works worldwide, thanks to its extensive terrain and obstacle databases.
• Regulatory Compliance: Meets international aviation safety standards (e.g., FAA, EASA).

Honeywell offers several EGPWS models, including:

• Mark V/VII: Advanced systems with improved processing power and expanded databases.
• Mark XXI: Designed for regional and business jets, offering lightweight and cost-effective solutions.
• Mark XXII: Enhanced features for helicopters, including hover and low-altitude flight support.
