737 NG - Position trend vector vs. GPWS Switch
During a visual apch into a very tight valley somewhere, two of my colleagues turned off the GPWS Terr Inhibit toggle switch on the FO side in order to avoid too many inputs. Apparently, this inhibited the Position Trend Vector on the ND as well - a feature which is nice to have in tight spots.
I canīt find any reference to this in any manuals - can anybody confirm the relationship between these two, and explain the background for it?
