54 Section 2 TAWS Operation Terrain/Obstacle Database Areas of Coverage The following describes the area of coverage available in each database. Regional definitions may change without notice. Worldwide (WW): Latitudes: S60 to N75 Longitudes: W180 to E180 Americas (AME): Latitudes: S60 to N75 Longitudes: W180 to W30 Atlantic (ATL): Latitudes: S60 to N75 Longitudes: W30 to E90 NOTE: Obstacles 200’ and higher are included in the Obstacle Database. It is very important to note that not all obstacles are necessarily charted and therefore may not be contained in the Obstacle Database. Navigation Database Pacific (PAC): Latitudes: S60 to N75 Longitudes: E60 to E180 United States (US): Limited to the United States plus some areas of Canada, Mexico, Caribbean, and the Pacific. As explained in the “Premature Descent Alerting (PDA)” section (page 59), <strong>Garmin</strong> TAWS Premature Descent Alerting (PDA) algorithms utilize data contained in the navigation database. It is therefore important to also have the latest navigation database installed to ensure correct TAWS alerting.
TAWS Phase of Flight The TAWS Phase of Flight definitions are listed below. •Enroute Phase - Defined as when the aircraft is more than 15 NM from the destination airport, or when the conditions for Ternimal, Approach, and Departure Phases are not met. •Terminal Phase - Defined as when all three of the following conditions are met: (1) The aircraft is 15 NM or less from the destination runway. (2) The distance to the destination runway threshold is decreasing. (3) The aircraft is at or below (lower than) a straight line drawn between the two points specified in Table 2-2 (relative to the destination runway). Distance-to-Runway Height-above-Runway 15 NM 3<strong>500</strong> Feet 5 NM 1900 Feet Table 2-2: Terminal Phase Distance-to-Runway versus Height-Above-Runway •Approach Phase – Defined as when all three of the following conditions are met: (1) The distance to destination runway threshold is equal to or less than 5 NM. (2) The height above the destination runway threshold elevation is equal to or less than 1900 feet. (3) The distance to the destination runway threshold is decreasing. •Departure Phase – Defined as when all five of the following conditions are met: (1) It has been determined that the aircraft was previously “on-ground”. (2) The aircraft has a vertical velocity greater than zero. (3) The aircraft has a groundspeed greater than 35 knots. Section 2 TAWS Operation 55
