![]() ![]() ![]() Honeywell is investigating options for improving the reliability as well as customer experience of downloading and writing EGPWS TDB files to PCMCIA Cards. Some have also indicated that the use of PCMCIA cards and related Ground Support Equipment (GSE) tools yield inconsistent results in the field. Operators whose EGPWS uses Linear Personal Computer Memory Card International Association (PCMCIA) Cards to update the TDB have expressed concerns that the older technology cards are becoming harder to acquire. In order to maximize EGPWS efficiencies, Terrain Database (TDB) Updates are routinely required. The purpose of the EGPWS is to help prevent accidents caused by Controlled Flight into Terrain (CFIT) or severe wind shear. Honeywell's Enhanced Ground Proximity Warning System (EGPWS) serves as an independent monitor using the aircraft’s position, altitude, air speed and glide slope, combined with internal terrain and airport databases to predict a potential conflict between the aircraft's path and an obstacle or terrain. Pilot situational awareness during operation and while taxiing is a critical component in ensuring safety. ![]()
