I do not have the charts at hand, but I flew there a few weeks ago and have flown there several times in the past months, and I think that at least in some SIDīs there are restrictions of speed up to FL 150 as you said (for sure there is one in the SID from LPA northbound, but they usually clear us to fly runway heading 3000ī and later higher level and no speed restriction, that is almost every time I have been there, so we end up not adhering to the published speed restriction to FL150).
the restrictions appear also in the FMS data, we use Jepessen charts and the FMS is a rockwell collins.
