Hi all,

 

After a feast of uneventfull flights, I decided to turn south in a mega ETOPS flight. Yesterday I started in Copenhagen heading for Rio de Janeiro. The Boeing 777 is a real work horse.

 

I am now heading from SBGL to YSSY. A 9000nm flight. A true test of range and ETOPS.

 

 

 

Here we are, a little over 6 hours into the flight and a mystical magenta path in on the TERR display. This is very near to the Date line.

 

Has anyone else noticed this problem.

 

...And in 12 hours time I shall fly straight back to Copenhagen from Sydney, thus circumventing the globe with only 2 fuel stops

 

I pushed a YSSY - KLAX out the other day (Delta Airlines DAL16) and didn't find any oddities crossing the date line (I had Apia, Samoa NSFA as an enroute alternate for ETOPS, which isn't far from the date line).

 

That said I havn't flown it that far south yet (Down into the S60's like you might ex SAEZ for instance).

That's interesting. I am now 2 hours further into the flight and the magenta "field" stopped at about 115w. The furthest south I am going is 72S

 

rgds,

Did you by any chance enter your arrival / approach before you were seeing the odd "magenta line". I discovered, coming into Boston, having installed an arrival with a vector segment, that I could see the magenta "vector-line" hundreds of miles from the airport, because it was pointing in my direction at such an angle that it was drawn on the map.

Hei Morten,

 

This is not a Vector-line, but more a huge area that has gone magenta. It's been like this for the last 3 hours. Now approaching 72S130W

 

If you leave SCCI heading for NZAA you'll see it about 90W

Ah, ok, got it, I'll check it out tomorrow.

The magenta areas are where the terrain database has no data.

 

If you're trying to look at terrain over the Pacific Ocean, you can safely say it's at 0' and turn TERR off until you're closer to land  :wink:

Would be better if that wasn't necessary. :huh:

 

If there is no data (and PMDG must know which areas are not covered) then assume it to be water at zero feet and display that instead of magenta?

 

Best regards,

Robin.

You're assuming. 

 

From the manufacturer:

 

If terrain data is unavailable for a particular area (within the 

region for a regional database), then Terrain and Obstacle 

alerting is not available for that area and the affected display 

area is colored MAGENTA

Makes sense, much better to know that there is no data = magenta, than not knowing if it is 0' or no data

down that far south you may be running into bits of Antarctica. Antarctica is ice covered land. Some of it quite high.
