Hi, well the quick answer is there is none. EGPWS does not use the WX radar. Let me explain: GPWS has 5 basic modes and use; Pressure Altitude, Radio Altimeter, Temperature and Baro reference. The Enhanced version, EGPWS uses an additional database to provide ND images and warnings for upcoming terrain. The WX radar can be used independently in 'mapping mode', also giving the pilots a picture on terrain ahead of the aircraft. However, the Enhanced function on the GPWS is now standard in modern commercial jet aircrafts and is much more reliable and accurate. I hope this helps
