250 knot speed limit

Why is everyone saying that 250 below 10,000 knots is a real life limit. I’ve seen multiple planes on FlightRadar24 not following it

Maybe because tower authorized them to fly over 250kts under 10000ft.

I always see a lot doing it though

Here´s a better explanation.

I’d also like if this rule we moved up to maybe 300 knots. Especially with larger a380s, it’s hard to takeoff and not hit that limit. Or have a button tower can press to authorize someone to go faster than the limit

Departure can cancel speed restrictions on ascent

Flight aware only records ground speed. It has no way of recording airspeed. The speed limit of 250 knots below 10,000 feet is your indicated air speed, not ground speed. If I’m flying my airplane at 5,000 feet at 250 knots, and I have a 50 knot tail wind, my ground speed is 300 knots. If I’m flying at 5,000 feet and I am indicating 200 knots with a 25 knot head wind, my ground speed is 175 knots.

Oh and Flight Radar 24 does the same thing as Flight Aware.

Some people listen to this man so I can stop seeing people post about this on the forum?!

No problem man, this was a really good question to get answered!

Nah, it’s more likely Approach.

@Riley_Dunshea Remember that Flightradar24 displays the Ground Speed.

In case you guys want some gee-wiz information, here are excerpts from the FAA7110.65 regarding speed. As an Air Traffic Controller, this is our operations manual.

Lastly, we can approve aircraft to exceed the speed limit and many carriers have waivers that allow them to exceed. Military aircraft are a great example!

That’s interesting Tyler. Does that mean that approach controllers should not request speed less than 210 for in bound planes when they are more than 20nm out.

Yes. I’ll post this in the controllers group. It’d be great to stick to this and allows us to expedite an aircraft’s arrival.

300 knots on the 380 is way too fast… Bear in mind the 380 flies pretty slowly on take-off and on approach.

I´ve never dealt with approach. Nor I remebered something like an Approach controler existed.

@Tyler_Shelton… MaxSez: Excellant post Tyler eventually our community will open the FAR, AIM or ICAO.

Since we have some no-US airspace in the reginal inventory here an excerpt that hi lights the International Speed Limit rules.
The origin of the 250 knots IAS limitation below 10000ft can be found in the ICAO airspace classes definitions. The ICAO airspace definitions include a 250 knots IAS limitation below 10000ft / FL100 in:
Class C: VFR
Class D, E, F and G: both VFR and IFR
That means that in class A and B there is no speed limitation below 10000ft / FL100. In class C, IFR has no speed limitation, but VFR has. In Europe you will find a lot of class A, B and C airspace below 10000ft. In the US, there is no class A airspace below 18000’ feet. There is class B and C airspace below 10000ft, but the FAA basically put a blanket speed limitation of 250knots below 10000ft, even inside class B and C airspace.
Also note that ICAO airspace classes are recommendations, countries have the authority to deviate from the ICAO recommendations as long as they publish these deviations. (Multiple Official Sources)

(Question; KNUC (San Clemente) a restricted government facility & falls outside the ADIZ/12 miles Conus speed restriction Zone! Why is there a 250 speed limit there? No such restriction is written in the Stations posted data or a speed restriction NOTAM on file) Anybody have an ansewer?

Great information, per usual! For KNUC, are you referring to in IF or Real World? In IF, I believe it was just an oversight. However, I’ve worked KNUC many times and I could only imagine the struggles we would face if users where allowed to enter the airspace at 250+kts.

If Infinite Flight ever reaches a point of going Global, I’d love to see the world diversified by their rules, rather than a “one size fits all”. It could make for an extremely unique experience!

MaxSez; Wise council as usual Mr. Shelton, I look forward to global flight. Your “Commanders Concept” of Future ATC goals would be useful. It would cool the jets of a few chromogen like me. Warm Regards
