(SPD) (LIM) Pseudo-Waypoint - Question not necessarily a bug

Featured Replies

Let me frame this one by saying that I am much more familiar with the Honeywell FMGC from my flying days, so I am not definitely saying this is a bug.

However...

Here the (SPD) (LIM) pseudo-waypoint is shown despite there being a restriction of 250kts on the STAR before the aircraft would normally decelerate to meet the 250kts @ 10,000ft restriction. In this case, the aircraft will never decelerate to met the 250@10000 restriction as it will already have decelerated to slow for the restriction at D356T at FL139.

Therefore, I would not expect the (SPD) (LIM) pseudo-waypoint to be shown on the F-PLN page, nor a magenta change of speed dot to be shown on the ND. I would expect it only to be shown if the aircraft was ever going to have to decelerate to obey this restriction.

The SPD LIM would be there, but it is drawn at the wrong place.

It has to be in between D356T and CDP in this case.

The speed change dot on ND would be somewhere prior D356T when the AC starts decelerating.
