Class C airspace is denoted by a heavy magenta border. Each distinct segment of class C airspace contains figures indicating the upper and lower altitude limits of that segment in units of one hundred feet, shown as a fraction, e.g., 100 over 40 indicates a ceiling of 10,000 feet (3,000 m) MSL and a floor of 4,000 feet (1,200 m) MSL.
Class A airspace exists within the entire Mauritius FIR (Flight Information Region), above FL245 ... The low-level speed limit of 250 knots (460 km/h; 290 mph) does ...
Additional speed ranges are specified for other segments of the approach. [1]: Table II-5-1-2 Table II-5-1-2 Approach plates generally include visibility requirements up to category D. [ 1 ] : II-5-1-3 While ICAO specify a top speed of 391 km/h for Category E, there exist no aircraft with an approach speed above this.
Airspace above the United States from the surface to 10,000 feet above sea level is limited to 250 knots (indicated airspeed) per the FAA's Federal Aviation Regulations. This speed limit hinders most modern-day tactical aircraft training operations, since low-level strikes are conducted almost exclusively at speeds exceeding 300 knots.
Class A airspace is generally the airspace from 18,000 feet (~3.4 miles, 5.5 km) mean sea level (MSL) up to and including flight level (FL) 600 (~11.4 miles, 18.3 km), including the airspace overlying the waters within 12 nautical miles (NM) (~13.8 miles, 22.2 km) of the coast of the 48 contiguous states and Alaska. Unless otherwise authorized ...
Los Angeles International Airport is surrounded by extensive Class B airspace, which is difficult for VFR traffic to navigate. In particular, the airport has four large runways running east/west that have airspace protection from 10,000 feet (3050 metres) down to the surface that is 25 statute miles wide (40 kilometres).
Use of instrument flight rules is also required when flying in "Class A" airspace regardless of weather conditions. Class A airspace extends from 18,000 feet above mean sea level to flight level 600 (60,000 feet pressure altitude ) above the contiguous 48 United States and overlying the waters within 12 miles thereof.

In Canada, the TCA is normally designated as class B, C or D. [5] In the U.S., the airspace of a TCA is typically designated as class B. In the U.K., the airspace of a TMA is usually designated as class A, D or E. In Australia and New Zealand, "terminal airspace" is not used both in common vernacular or publication and legislation. However, the ...
