TBM speeding violations?

Hi all. I was wondering why I received speed violations for going 300kts IAS at FL140? It was my first time flying the TBM, I read that i max speed is 320 or something, so I don’t know why there was a problem. I literally looked away from my phone for 15 seconds, and I received 4 violations. I haven’t had this problem before.

320knots in ground speed, not IAS.

Do the violations follow ground speed or IAS? I am pretty sure it is IAS, although I could be wrong. It’s been a few years since I’ve received a violation.

Each aircraft has their own limit. The TBM limit is much lower.

For example the limit in the TBM at 14,000 is about 265 kts.

I have been there before… with the TBM, initial climb 125 kt AS, then up to 180 kt AS, then aim for ,50 to ,52 cruise speed (GS).
