Transponder Types
I fly quite a few aircraft all of the same type but with different transponders. How can tell what mode type they are? They dont have written on the front of them this is a mode X type transponder. Most are the simple ones you just dial up the code and switch to on. Can you be seen by TCAS equiped traffic with these types?
One of the aircraft has been upgraded, small and round switch it on and the screen digitally showns 7000 and FL, what type is this?
Should really ask somebody at the flying club but I only usually fly locally VFR
