When is TSO needed for IFR?

[Howard Handelman]

Radio?
Transponder?

I know the transponder has to pass the IFR performance check, but does it need to be TSO's in an experimental?

What about the radio?

Thanks

No clue but personally, I'd rather not be in hard IMC and relying on something that isn't. Just my two cents....your mileage may vary.

A TSO is required when the regs say it's required. For example, 91.215 requires ATC transponder equipment installed to meet performance and environmental requirements of TSO C-74b, TSO C-74c, or TSO C-112.

Nothing at the moment requires a com radio to meet any TSO performance requirement.

I agree with Steve.

I'm all about being prudent, Steve.

IFR and icing conditions are no-play zones, IMHO. "Gooder enough" doesn't cut it. Either one has the proper equipment as laid out based on years and years of experience or one doesn't, IMHO.

Not all rules are meant to be broken.

That's why I'm firmly in the Very Nice Day VFR only world of flying, where one wing over the centerline on landing counts as precision enough.
