P is the FAP (published glide slope intercept), IF the intermedieate fix. D is calculated by the charting provider as a convenient position to start final descent.
In this case, it actually helps and is relevant to the published Airbus guidance.
Which is (for decelerated approach)
- Intercept G/S at S speed and CONF 1, at 2000' AAL set FLAP 2, then gear down then the rest successively. Stable at 1000.
- If the intermediate altitude is at 2000' AAL or lower[*], set flaps 2 at G/S one dot below, and gear down with G/S intercept.
[* = but not below 1500 ft AAL].
StrIA's picture has one solution: intercept final at 5.1 WGD, be fully stabilized at that point already, it is close and low.
Mine offers a different technique: to keep 600 meters from the IF, flying level with S speed and CONF 1, and use the second / short version of Airbus OEM decelerated approach described above - using the "D" position. Of course, you do not really need a chart to do it this way, but it is more comfortable and reassuring with it to crosscheck and more importantly, plan ahead.
