I was recently informed by tower that my altitude wasn't being reported accurately. Unfortunately, my local field doesn't have any avionics shops handy to diagnose the issue, and it's going to be a while before I can fly it somewhere to have it looked at.
In the meantime, can someone answer for me a question -- is it legal to fly class-D airspace without mode-C enabled? There's no class B or class C anywhere near me. My understanding from the regulations is 'yes', but I'm looking for a second opinion just in case I misread something.
Furthermore, does one advise ground/tower of this prior to departure? or do you just take off with the transponder switched to 'on' instead of 'alt' and they don't care?
