Relevance Of "grid" on PFD

Recommended Posts

R2dL4OW.jpg

Evening gentlemen/ladies, can somebody please tell me the relevance of the white box with the text "Grid:332" , thanks in advanced.


Am I supposed to put my overly priced and powered computer specs here? Sorry, I must have no tolerance for idiots who do that.

So when's the PMDG 777x gonna' be released?

-Sincerely, Shawn O.

From what I understand its just another heading to reference if the ADIRU fails. 

 

If the ADIRU fails, SAARU (Secondary Attitude Air Data Reference Unit) would work but would need heading input every 10 minutes.

 

Not 100%, but FCOMv2 pages 11.20.5 and 11.31.8 makes me think that.  I've seen this on my 3 or 4 polar routes.

 

Maybe someone else can hit on this.

7160N is not far off Greenland's coast and in the situation of decompression its be best to know whats below when approaching the divert, IMO its best to keep it on.  Haven't seen a cockpit flow that says turn it off after climb or over water.  Also why would Boeing add the option to show large bodies of water if it wasn't meant to be kept on over water? 

 

Also I doubt Google will yet anything more then FCOM on GRID headings.

 

Also the terrain feature is not a radar but rather a database of terrain.  If it was a radar if would not know the terrain behind say, a mountain as the 'radar' would be blocked.  As well wouldn't be able to show terrain that's beside the plane (90 degrees left/right).
