The CJ2+’s terrain awareness warning system (TAWS) is powered by the L-3 Communications LandMark 8000 platform. This state-of-the-art TAWS compares GPS information and altimetry data against internal, worldwide databases of navigation, terrain, and obstacles to predict aircraft position and warn of potential conflicts. It displays terrain contours using multiple color shades, graphical depictions of runways (>2,000 feet), and depictions of any obstacles. Pilots will get five basic alert modes: Forward Looking Terrain Avoidance (FLTA), Premature Descent, Excessive Descent Rate, Negative Climb Rate, and Descending to 500 Feet. Aural advisories are provided through the aircraft audio system and are visually displayed on the PFDs and the MFD. The three main databases can be updated periodically via subscription through L-3 Avionics, using a data port in the avionics bay. Key features of the system include:
• Display interfaces for MFD, radar, and EFIS
• 900-knot speed performance
• Enhanced altitude depictions with 11 color gradations for crisp, easy-to-interpret imaging
• Integrated with the CJ2+ GPS receiver
• Altitude call-out and selectable aural alert phrases
• Installer-selected panel indicator lights and switches
• Includes all FAA TAWS B–mandated alerting modes
