4.2. OPERATIONAL RECOMMENDATIONS FOR TAWS
4.2.1. FOR THE AIRLINE
. Operate your aircraft with the latest terrain database provided by the TAWS manufacturer. Refer to SIL 34-080 (See AIRBUS References) for more information on terrain database update. Terrain database can be downloaded at:
-EGPWS: http://www.honeywell.com/sites/aero/Egpws-Home.htm.
-T2CAS: http://www.acsscustomerservices.com/CustomerServices/.
Note: States that are ICAO members provide the TAWS manufacturers with the terrain database contents. Each State is responsible for the definition of the terrain database content. The operator is responsible for verifying the correctness of the terrain database contents with the appropriate State in which the operator operates. The operator shall report errors in the terrain database to the appropriate State and its TAWS manufacturer. AIRBUS SAS does not accept any liability for the contents, acquisition, use or update of the terrain database.
.
Report any repetitive difficulties with a given airport to AIRBUS via your Customer Service Director (CSD).
.
Train your flight crews to use TAWS and to respond to TAWS alert safely and efficiently.
.
Take cognizance of the Flight Safety Foundation (FSF) Approach-and-Landing Accident Reduction (ALAR) tool kit (available at http://www.flightsafety.org/ecommerce/) and spread out its contents inside the company as necessary.
4.2.2. FOR THE FLIGHT CREW
.
Stick to the procedures. Refer to your FCOM for the appropriate procedures. Refer to FOBN “Operating Environment – Enhancing Terrain Awareness” (See AIRBUS References) for a comprehensive set of recommendations.
.
Know where you are, Know where you should be, and Know where the terrain and obstacles are.
.
Check the altimeter settings (reference – standard, QNH, QFE – and units – hPa, inHg, meters, feet). Refer to FOBN “Supplementary Techniques – Use of Radio Altimeter” (See AIRBUS References).
.
Know how your TAWS operates.
