ok, new question, what is the ratio to work out how fast it's allowed to go?

Must be <250 knots IAS at all times when under 10,000 ft.
Must be <200 knots IAS when in Class B airspace.

There is no speed limit above 10,000 ft.
Hope that answers your question.

Apart from the limit on over-land supersonic speeds the maximum speed of any plane is limited by its design. All aircraft have a minimum flight speed at which they are about to stall, and a VNE (velocity never exceed) at which there are control problems imminent or bits start to drop off. Yes I know Concord dropped lots of bits in service but that's french engineering. For most airliners the stall is around 120-150 mph and the VNE is 600-700 mph. Light aircraft much slower. Helicopters have a zero minimum speed, but the maximum is limited by the rotor blades; as it goes faster the blade on the side thats swinging backwards loses air speed, eventually giving control difficulties. Max speed is around 160 mph. The "Airwolf" supersonic helicopter was a scriptwriter's special!
Of course there are also speeds imposed by Air Traffic control, but these can be ignored by the pilot at his discretion, though he may well have to justify himself later

When you are referring to the speed of an aircraft you have to specify if you are talking about
"Ground Speed" Which is no use at all to an aircraft flying.
"True Air Speed" Which is the speed the aircraft moves in the Air.
"Indicated Air Speed" Which is the speed that keeps the aircraft in the air.
Is this last one which is limited by the design of the aircraft and the altitude it flies.
Too fast and the aircraft might exceed the limits of air pressure and could brake down or it could try to reach the speed of sound and might brake because of the vibrations.(The Concorde was designed to do it).
If the IAS is too low the aircraft simply stalls and falls off the sky.
Now you know a bit more about speed.

Pilots are expected to fly at a speed which is reasonable considering the type of aircraft they're flying and the conditions they're flying in. Other than that the only 'speed limit' that the FAA enforces is that civilian aircraft are restricted from flying supersonic (not a big problem since there are very few mach-1 capable aircraft in civilian hands) in U.S. airspace, and military aircraft can only exceed mach 1 in a genuine emergency.

And no fair sneaking in a second question!

There are laws established by the FAA about maximum speeds. The maximum speed depends on altitude. There is an exception if the plane cannot be operated safely below a speed faster than the maximum. If this is the case, you cannot operate faster than the minimum speed recommended in the Aircraft flying manual.

Yes it all depends on the what the design characteristics of the airframe are, bear in mind though that if the airframe is stressed beyond this it can start to collapse (overspeeding)

Have a look at any site to do with aircraft production i.e EADS or airbus and download the reference material as the theory is very complex but easy to understand.

Good Luck

No speed limits in the air!

To avoid nuisance from sonic booms, supersonic flights must be conducted at least 10NM from any coastline (on the sea side!), and on a course that diverges away from the mean angle of the coast by at least 10 degrees.

Of course, any aircraft type will have its own particular speed limit depending on its own performance!

All flight autos use the comparable aerodynamics. There are 2 person-friendly recommendations. the 1st and best is the regulation that states that when a medium alongside with water or air strikes it creates suction and pulls issues in direction of it perpindically. you could exhibit this concept via keeping a peice of paper on your decrease lip and blow, the paper will upward thrust in view that a vacuum is being created. the splendid of the wings are bowed and it creates swifter moving air then the backside this is flat. the different concept is which way the wing is slanted. This creates short-term carry. while a airplane takes to the air the wings are slanted and it creates carry via pushing the air down, this pushes the airplane up no longer pulls it up. This concept applies extra to helicoptors. yet at cruising altitude they change from pushing the airplane as much as permitting the aerodynamics to improve the undemanding or helicoptor.

there are speed limits in the air
1) above 10,000 MSL= no limit
2)below 10,000 MSL = 250 knots
3)There is NO published speed limit in class B airspace exept the rule2 still applies
4) there is however 200knot speed limit BELOW the class B airspace
5) When at or below 2500 ft. AGL and within 4 NM of the primary airport of Class C or Class D airspace,. the speed limit is 200 kt


MSL= measured sea level
AGL= above ground level

I believe I'm right in saying that over land and territorial waters, airspeed must be sub-sonic, I do however, stand to be corrected!


Concorde was only allowed to go supersonic when out over the sea.

Mach at sea level.
