Section 1: Introduction Overview PART FOUR TAWS INTERFACE Garmin’s Terrain Awareness Warning System (TAWS) is an optional feature for the GPS 500 and GNS 530/530A to increase situational awareness and aid in reducing controlled flight into terrain (CFIT) (Figure 1-1). Garmin TAWS satisfies TSO-C151b Class B requirements for certification. Class B TAWS is required for all Part 91 aircraft operations with 6 or more passenger seats and for Part 135 turbine aircraft operations with 6 to 9 passenger seats (FAR Parts 91.223, 135.154). Operating Criteria Garmin TAWS requires the following to operate properly: • The system must have a valid 3D GPS position solution • The system must have a valid terrain/obstacle database GPS Position and GPS-MSL Altitude Garmin TAWS uses information provided from the 500 Series GPS receiver to provide a horizontal position and altitude. GPS altitude is derived from satellite measurements. GPS altitude is converted to a Mean Sea Level (MSL)-based altitude (GPS-MSL Altitude) and is used to determine TAWS alerts. GPS- MSL Altitude accuracy is affected by factors such as satellite geometry, but is not subject to variations in pressure and temperature that normally affect pressure altitude devices. GPS-MSL Altitude does not require local altimeter settings to determine MSL Altitude. Therefore GPS altitude provides a highly accurate and reliable MSL altitude source to calculate terrain and obstacle alerts.
