You want me to educated myself ? That is a great response for someone so well informed ! lol Please do educate me ! So again SID/STAR doesn’t have to be within 10k as you previously stated. Something is very wrong with you. My statement is quite clear: during a SID or STAR, the max speed is 250 up to 10K unless otherwise restricted. Additionally, 250 can be exceeded under certain conditions. There is no mention of the SID or STAR being limited to 10K. I'm not sure how much clarity you need. This is what I said: "mentioning about the speeds, SIDS and STARS are designed to keep the airplane within the protected airspace up to 10K at 250 KTS" "My statement was about the speed of 250 (or whatever is posted) below 10K during SID X STAR" 747 Captain for the last 39 years, and still learning.

As I mentioned before SID/STAR is designed to help ATC traffic flow. Below 10 K 250kts restriction (here in US) as per 91.117 (a) is everywhere. In other words, 10k 250 kts restriction is unrelated to SID and STAR at all. SID/STAR speed and altitude restriction in its own realm, and only fall back to 91.117 if no speed or altitude restriction specified. "Protected airspace" is another interested term. There are controlled, special use, prohibited, restricted and etc airspaces. "Protected airspace" is very vague detention. The only reference of "protected airspace" I can think of is related holds. So basically the airspace is protected for maneuvering during entry, procedure turn, inboud/outbound legs and etc Life time flight sim enthusiast, current airplane owner 172P (past C182F).

"Protected airspace" is another interested term. Ok, I'll try this. Criteria is not only to help traffic flow. It's more elaborious that that aspect, it provides transitions from/to runways, airways, protection of obstacle clearance creating a protected area, (airspace) associated with for manuvrability within certain distances or turn radius to keep the airplanes within minimum safe altitudes, minimum climb gradients, avoids conflicts, avoids restricted areas, military zones, noise sensitive areas, climb or descend constant profiles profiles to reduce fuel burn and noise, all based on FAA, ICAO, EASA, CAA etc rules. About 250 KTS below 10 K, yes, it can be exceeded under a few requirements, and a few places around the world don't have this requirement. 747 Captain for the last 39 years, and still learning.
