Airspeed restrictions.

[JVC_systems]

Hello people,
I was wondering what are the speed restrictions in other countries besides the U.S.A.? In USA you should not be going more than 250 if you are bellow 10,000feet. I was wondering what are the speed limits in other place, how about Canada for example, Australia, Europe, Asia? Do they have to use the same speed restrictions as the United States or do they use their own if they even have any? Thanks.

in Europe we also have: not over 250kts when bellow FL100

That's intersting, how about in other places? Asia, Afrika?

As far as the manual for the Tu-154 goes, it's 500 kmh below 3000 meters in russia

Ivan,
How many feet and knots is it? I think 3000metter should be around 10,000feet how about kilometers?

[Ivan]

it's some 10000ft... didn't cross-check the speed with the shift-z display, but should be somewhere between 220-280 kts

[JVC_systems]

I see, so looks like it is a standart rule for aircrafts to fly less than 250 if below 10,000feet. I was also wondering why...Is it because of the birds or is it because of the amount of noise jet engine produces?

[Ivan]

could be noise, but separation equalizing too.

when the jets just appeared (DH comet, Tu-104) there was no speed restriction... they came not that much faster though (less engine power).


Military flights are not speed restricted below 10000 ft

How about in places where they aren't that many people. Fiji islands for example or North/Soult poles? Do they have their own rules there for speed restrictions?

normally its 250kts below 10 000ft, unless ATC says "No speed restictions" then its balls to the wall  ;D which is always great fun

I think there are several reasons, but they may not be obvious to the general public.
Slower speeds reduces the workload for air traffic controllers, imaging how fast the ATC have to act when every aircraft came thundering along at some 300kts while awaiting vectoring. In busy airspace there would just be more dangerous to fly faster.

I hate to step on your toes..............but why break with tradition!  :-[  :)     It actually may be easier when aircraft are expedited away from a particular sector. Case in point: Houston Center and Approach, over the past few years have been experimenting with a "high speed" program. It IS legal to go over 300kts below 10,000' in the Houston area, with ATC's approval. In fact, most of the time I fly to the Houston area they assign high speed climbs and descents. Descending is not a problem, but during the climb, maintaining 300kts+ means that by the time I hit the lower 20's, my climb rate is Cessna-ish! Great for ATC(they get rid of one more airplane that much faster), bad for me.  ::)

OTTOL, dang you americans  ;D

I wouldn't mind higher speed limits below FL100, but many of my buddies told me the speedlimit is applied for safety reasons. I'm certainly not an ATC wiz at all, but its sounds pretty logical?

Just proves that you Yanks are crasy indeed  ;D

I think it's not a prob of ATC, it's a prob of VFR flights. I don't think to have a chance in my glider against a 350kts jet.

[Nexus]

Would you have a bigger chance against a Boeing 777 coming in at 250kts? Wake turbulence is more violent in slower speeds if I'm not mistaken. But I guess it buys  you more time to react so you have a good point.

I still beieve it's much easier for ATC to handle the trafic if they were all flying at near the same speed  :)
(Yeah, I'm boneheaded)
