Is a transponder required above Class C airspace?


Is a transponder required above Class C airspace? Specifically, a Mode C transponder is required if you wish to operate in Class A, B, or C airspace, at an altitude of over 10,000' MSL, or within a 30-nautical mile radius of the primary airport in Class B airspace.


Do you need ATC clearance for Class C airspace?

The approval needed to enter Class C airspace is like Class D in that you do not need a specific clearance, but you do need to establish two-way communication with control. To be able to enter Class C airspace, a pilot must contact ATC prior to arrival.


What are the exceptions to the Mode C veil?

Mode C Transponder and Airspace In order to travel within this airspace, you absolutely must have the proper equipment, unless you are one of the exceptions – a glider, a balloon, or an aircraft without a certified engine-driven electrical system.


Do I need a transponder if I have ADS-B?

For aircraft operating at or above FL180 (18,000 feet), you must be equipped with a Mode S-transponder-based ADS-B transmitter. For aircraft operating below 18,000 feet and within U.S. airspace, you must be equipped with either a Mode S transponder with Extended Squitter or a Universal Access Transceiver (UAT).


Can you fly VFR in Class C?

Separation is provided within the Class C airspace and the outer area after two-way radio communications and radar contact are established. VFR aircraft are separated from IFR aircraft within the Class C airspace by any of the following: Visual separation. 500 feet vertical separation.


Do you need a transponder above Class C?

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. Call ATC on the radio before you're in Class C airspace and make sure to tell them: Your position.


What is the difference between a transponder A and C?

Civil aircraft may be equipped with transponders capable of operating in different modes: Mode A equipment transmits an identifying code only. Mode C equipment enables the ATCO to see the aircraft altitude or flight level automatically.


Which transponder code to avoid?

Code 0000 should never be assigned or used. However, NASA recommends that crews set 0000 after landing to help detect when a clearance has not been received. Resetting the transponder to 0000 (four zeros) after landing can help you, or the next crew, detect lack of a PDC.


Which class of airspace does not require an ATC clearance?

Most airspace in the United States is class E. The airspace above FL600 is also class E. No ATC clearance or radio communication is required for VFR flight in class E airspace.


Can you fly over Class C airspace without ads-B?

As described in 14 CFR 91.225, ADS-B Out performance is required to operate in: Class A, B, and C airspace. Above the ceiling and within the lateral boundaries of a Class B or Class C airspace area upward to 10,000 feet MSL .


Can an aircraft without ADS-B out equipment overfly class c airspace?

Can aircraft without ADS-B Out equipment overfly Class C airspace? Yes, but only in exceptional circumstances because flight over Class C airspace is not permitted without appropriate ADS-B equipment.


What is the regulation for Class C airspace?

The ceiling of a Class C airspace should be 4,000 feet above the primary airport's field elevation. The surface area extends from the surface to the upper limit of the airspace. The floor of the airspace between the 5 and the 10 NM must extend from no lower than 1,200 feet AGL to the upper limit of the airspace.
