It depends what aircraft and what speed you are going
The official max speed of the F15 is Mach 2.5, although some publications list Mach 2.8. This is without external stores or armament.
The Cirrus SR 22 has a max speed of 183 knots. That's pretty good for a small private aircraft.
The Airbus A380 which has a Max Mach of 0.96 (96% of the speed of sound).
Mach 1.8 (1,191 knots, 2,205 kph) source Wikipedia
The A-10 pilots are proud to be "low an' slow" -or "in the mud" with their tough aircraft at a max speed of 440 mph.

160 knots or 185 miles per hour (max or "never exceed speed") this aircraft is not capable of this speed in level flight. The maximum speed in level flight is around 125 knots.
The posted speed limit is the max speed.
There really isn't a max speed of an F/A-18 landing on an aircraft carrier because: (skip to the bottom for the general and quick answer which is just a guess) 1) If the aircraft was going too fast, the tail hook would break upon hooking onto the wires 2) If the aircraft was going too fast, the wires the plane uses to stop would snap when the tail hook hooked them at a high speed 3)If the aircraft was flying over a speed of 240 knots (nautical miles per hour) the planes landing gear and flaps would automtically retract 4) The perfered speed to land (or the speed you should be traveling if you are doing everything right) should be 135 knots 5)If you were going too fast, the Landing Signal Officer (or LSO) would tell you to wave off (or abort the current landing pattern and realign for a new landing) So if there had to be a max speed to land on a carrier I'd say it would probably be about 150-160 knots
The average cruising speed of an airbus varies by the type of the aircraft, it is generally between 450-537 mph. Again the same can be said for the cruising altitude depending on aircraft and route, as a general rule it is between 36,000ft and 39,000ft (the service ceiling (ie the max cruising altitude) of some airbus aircraft is 41,000ft). Hope this helps.
The max speed of the final Spitfires was about 460 mph.
