OK so it does take "some" runway data base info but...
How come if you program runway 24L and at the last minute they change you to runway 24R more than 1/2 mile away you don't get a warning?
Also if you do a "circle to land" procedure you would have programmed the initial runway for the approach and then have to manoeuvre to the other runway perhaps more than 2 miles away at low altitude how come there is no warning then?
Could it be because the aircraft is "configured to land"?
The only time one of our crews got a warning was going into the new Athens airport many years ago. Obviously it was not in the EGWPS’ data base ad had to be turned off for the landing.
In this incident if there is no runway info in the data base of the EGWPS and the aircraft is fully configured to land, how would it know the pilots are landing on the wrong runway?
