Data button functionality survey

[Icarus747]

I noticed the other day when I press the DATA button it shut off the time AND fix constraint on the NG.  Having checked the boxes in 4 of our airplanes, the FTD, and one sim, none of them do this.  It only turns off the time.  The fix constraint is always displayed.  Of those of you who actually fly this airplane, what does your aircraft do?  I'm wondering if this is a custom function based on customer wants, or if they all work that way.

Where exactly did you look at? At the first constraint waypoint or at all waypoints?

In PSX -- NG and legacy FMC --, when the DATA mode is off, the first altitude constraint is still shown on the ND.

When you have this on the LEGS page ...

AAA ---/-----
BBB ---/12000
CCC ---/15000

... the ND will display this when the DATA mode is OFF:

AAA
  |
BBB
12000
  |
CCC
  |

... the ND will display this when the DATA mode is ON:

AAA
  |
BBB
12000
  |
CCC
15000
