May 3, 201115 yr Hey gurus,just asked myself if the NPS indications were actually an airline selectable option, or maybe they are tied to the new Collins AFDS? Thing is, when I once flew one of the NGs with the older Honeywell MCP a couple years ago I simply cannot remember to have noted any NPS indications, nor can I find them on any picture I took. I understand they should be visible during descent only, but I just double checked and they were really not there. Just being curious if they are a complete independent option (regardless of other installed systems) or tied to some other system selection.
May 3, 201115 yr My understanding is that NPS is an option.NPS is displayed in all phases of flight (not sure if they are displayed on the ground) so that crew can monitor navigation performance.
May 3, 201115 yr Author Yeah,right now I am not quite sure as to why I thought it was only there during descent. Couldn't check atm but you might be right. Thanks for the reply. :(Oh, and I'm pretty darn sure they're not there on the ground - there isn't quite any RNP... :( Edited May 3, 201115 yr by badderjet
