Landmark TAWS - Terrain Awareness Warning System
 
Landmark TAWS 8000

The LandMark™ model 8000 is one of the most cost effective ways to add TAWS to existing EFIS, MFD, or Radar Indicators. Designed with late model or upgraded cockpits in mind, the LandMark™ 8000 utilizes compatible ADC and GPS inputs to provide accurate terrain data on your aircraft's existing display. As one of the most affordable Class B TAWS, the LandMark™ 8000 economically satisfies the FAA mandate for turbine-powered aircraft. Both LandMark™ 8000 and 8100 models have been tested to 900 kts, assuring reliable performance in any class B jet or turbo-prop.

With four times the resolution of other Class B TAWS, both the LandMark™ 8000 and 8100 models provide an accurate lay of the land with crisper imaging, distinct runway & obstacle depictions and enhanced alerting capabilities. Improving upon earlier Ground Proximity Warning Systems (GPWS) technologies, the LandMark™ systems add features such as look-ahead capabilities, longer warning times, landing configuration operability, and greater situational awareness via an optional terrain display.

The LandMark Class B Terrain Awareness and Warning System incorporates five basic types of alerting modes to provide critical information in a timely manner. They include Forward Looking Terrain Avoidance (FLTA), Premature Descent, and GPWS Modes 1, 3 and 6. Although separate in their functionality, together these alert modes provide you with comprehensive and accurate situational awareness to guide you safely to your destination.

Forward Looking Terrain Avoidance (FLTA) FLTA includes warnings for Reduced Required Terrain Clearance and Imminent Terrain Impact (ITI) which occur when the aircraft is above (or below for ITI) the altitude of the upcoming terrain along the projected flight path, but the projected terrain clearance is less than the required terrain clearance.

The Premature Descent alert occurs when the aircraft is significantly below the normal final approach flight path to the nearest runway.

GPWS Alert Modes:

Excessive Descent Rate alert condition occurs when the aircraft is descending too fast for the current height above terrain.

Descending To 500 Feet call-out occurs when descending within 500 ft of the terrain during enroute mode or when descending within 500 ft of the nearest runway threshold elevation during terminal or approach mode (not pictured).

Negative Climb Rate (or Altitude Loss After Takeoff) alert occurs after takeoff or missed approach after the aircraft reaches 50 ft above the runway, but before reaching 700 ft above the runway.
