What is the max airspeed in Class B airspace?

The maximum airspeed below the Class B airspace area is 200 knots and the max speed inside the Class B airspace is 250 knots even though the maximum speed below 2,500 feet above the sur- face and within 4 nautical miles of a Class C or D airport is 200 knots.

Yes, there are lots! Below 10,000 feet above sea level (ASL), all aircraft are restricted to 250 knots (nautical miles per hour). A limit of 200 knots is required when aircraft are within 10 nautical miles of the airport and when they are less than 3,000 feet above the ground.

What is the speed limit in Class C or D airspace?

230 mph
Speed Restrictions In Class C/D Airspace No person may operate an aircraft at an indicated airspeed of more than 200 knots (230 mph) at or below 2,500 feet above the surface, within 4 nautical miles of the primary Class C or Class D airport.

What is the difference between Class C and Class D airspace?

Class C airspace is used around airports with a moderate traffic level. Class D is used for smaller airports that have a control tower. The U.S. uses a modified version of the ICAO class C and D airspace, where only radio contact with ATC rather than an ATC clearance is required for VFR operations.

Can you fly over C airspace?

While you don’t need an operable transponder to fly below a Class C shelf, you will need one to fly above Class C airspace. As you approach a Class C airport, you’ll contact that airspace’s approach control.

What is required for Class C airspace?

Class C service requires pilots to establish two‐way radio communications before entering Class C airspace. If the controller responds to a radio call with, “(a/c call sign) standby,” radio communications have been established and the pilot can enter Class C airspace.

Can a student pilot enter Class C airspace?

Is radar service mandatory in Class C airspace?
