Do you need a transponder above 10000 MSL?
However, if you wish to operate in class A, B, or C airspace, or at an altitude of over 10,000′ MSL, or within a 30 nautical mile radius of the primary airport in class B airspace, you will need a transponder and altitude encoder (commonly referred to as “mode C”).
Where are transponders required?
Required for all aircraft in Class A, B and C airspace. Required for all aircraft in all airspace within 30 nm of an airport listed in appendix D, section 1 of Part 91 (Class B and military) from the surface upward to 10,000 feet msl.
Do you need a transponder below Class 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.
Can you fly without transponder?
Yes, you can in the US in Class D, E & G airspace according to 14 CFR 91.215. You will need to placard the transponder INOP, and make a note in the aircraft logbook. But, you must stay out of any Mode C Veils, and further than 30 miles from Class B airports.
