  • Can someone explain all differences between these two?
  • EGWPS has 7 modes… 6 modes are same as GPWS… 7th mode is WIND SHEAR WARNING…In mode 6 additional mode called as 6B which is bank angle alert…
  • Gpws is real … As in the ground under you … It warns you of actual terrain while EGPWS works of a database based on your navigation system is give you a predictive warning based on your lateral position given by your nav FMS. And its own database. This warning doesnt necessarily mean there is actual ground under you … It means that based on your path speed and cross checking with its terrain database a potential impact is imminent .
