Speed restriction, Canaries
Hello colleagues
Our FMC has a standard setting of 250 kts up to FL150 on departure from the Canary Islands.
This difference from standard speed schedule is not published on the Jeppesen plates. Not on the initial information pages for the different canary islands, not on the SID-plates and is not a TMA-restriction.
Rules and regulations within Spanish airspace also states 250 kts up to FL100 as standard.
I know there is a restriction of 250 below FL150 on arrival, but that shouldn't be an adequate description of why the same restriction is on departure even when there is nothing published.
Can it be airspace classification?
Any good answer would be of great interest
Thanks guys.

Kristian, a lot of differences between charts and FMC databases are created by having chart supplier "A" and database provider "B", a cost factor these days. I saw charts where the go around procedure was drawn the wrong way, the wording showed the correct turn, the FMS asked for no turn....
After many emails both suppliers apologized and corrected the errors.
In your case, the AIP does not ask for a departure speed limit above FL100, and this is the final document for everyone.
You may, however, consult your OM as there may be a limitation for the Canaries based on company ideas, but this is another story....

Thanks. Our OM says nothing about the subject.
It bugs me that I can't find any definitive answer about this, but I'll just have to live with it as it is.

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 SID´s 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 3000´ 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.

I may well be wrong, but......
I believe it is class D airspace below FL150, therefore the slower you go (250kts max) the more chance you have of spotting someone else.

Hello folks
The AIP specifies the speed limit of 250 kt below FL 150 for STARs RWY 03/21 for GCLP.
There is a free access to AENA AIPs.
Check. www.aena.es - NAVEGACIÓN AÉREA - AIS - AIP

I found the answer. It's a general speed reduction area in the Canaries TMA, very likely because it's D/E-class airspace.
It can be found in Spanish AIP ENR 6-6-9.
Cheers

The speed restriction is written on the Jeppesen STAR chart and airport briefing chart, as well as on the LIDO charts. On the SID chart's it is not mentioned however.
Only half a speed-brake
May I suggest it is perhaps a limitation of "modern" FMS software. If there was a 250kt/FL150 limitation for arrivals (as you'll seem to agree), the database coder has two options:
- to code it for the airport which means it will show up unnecessarily for departures, or
- not to code it which means it will not show for arrivals contrary to the AIP.
What would you do?
Either way, many call me a computer kid. Fine, as long as we agree that being a "happy magenta man" requires understanding that computers are never correct until cross-referenced otherwise.
If you don't agree with the FMS code, what stops you from flying the correct profile?
If you don't agree with the FMS code, what justification you have to follow it instead of flying the correct profile?
Sincerely,
FD (the un-real)
