Hello everyone.When I press the Terrain button on the EFIS panel I see the word "TERR" displayed on the ND. Just under this there are two 3 digit numbers, these numbers change quite often and are yellow on the ground,green in the air,and sometimes one will be red depending on the range selected. Can anyone tell me what these numbers are telling me? I have searched the manual for this info but I am just not finding itThanks.Dennis

the bottom number is the altitude of the lowest terrain within the selected range, and the top number is the altitude of the highest terrain within the selected range

1. Highest terrain altitude in your route (inside Cyan marks)2. Highest terrain altitude in ND screen for selected range

1. Highest terrain altitude in your route (inside Cyan marks)

Bryan had it right.The cyan, dashed lines show the sample space for terrain on the VSD. The terrain numbers and cyan lines have no direct correlation.

The cyan lines are the "enroute swath" and are the area on the ground that the VSD is depicting when you have it enabled.

Thanks for the response guys.Could you clarify what the numbers mean for me. Let's say I am at the gate at Nurnberg (I just was) and I press the Terrain button,and on the display I have two 3 digit numbers...020 / 014. What are these numbers referring to exactly? Is it a measure of something in feet / meters? If I increase the range to 80 miles the top number changes to red and is now 047. What am I being told here?Thank you so much for the help everyone.Dennis.

It refers to the altitude of the terrain in hundreds of feet, also known as "flight levels." While FL isn't the correct term, they follow the same practice. So 020 is 2000 feet, 014 is 1400. So the lowest terrain on your display is 1400 feet, and the highest is 2000.When any number is in red, or if the terrain is red, it means it is at or above your current altitude. (PS, It may also include terrain 500 feet below you and up or something like that, but I don't know the specifics.)

Eric.Thanks so much,that is just what I needed.All the best.Dennis

Since we talking about this :) why can't I see the terrain on the first officer ND? Only on the captain ND even though I press on both. Second question; could the ngx ever alert me on windshear?ThanksWilson

As for your first question. It´s only modeled on Capt display. It would taketo much resources with both. That wat PMDG said (Similar anyway)/ Leffe
