I was explaining to a group of aircraft how the "heavy" designation is not necessary in enroute airspace. Both of these pilots were VATUSA Instructors (I didn't know at the time) and it seemed as if one of the Instructors was upset that I had given the explanation. I went on to explain that we all make mistakes and that I wasn't trying to be rude. I think that the situation concluded positively, so kudos to the Instructors.

Just a point of clarity, and I wasn't there for the conversation, so some of this may have been covered.
Enroute.."Heavy" may be omitted except for the following:
- communicated with a Terminal facility
- communications when the Enroute Controller is providing approach services (which is often!)
- communications when separation may be less than 5 miles via LOA or procedure
- when providing traffic advisories
While not required, pilots should make their initial call to a enroute center with the 'heavy' callsign; subsequent communications do not need to be prefixed with 'heavy'. All terminal phase operations require the heavy callsign with all communications.
I *think* this is all correct.....like the thread, I reserve the right to be mistaken
