There is another thread on the Instructors forum, where someone has accused FI's of being pedants. In terms of phraseology I think BEagle has proved that it may be true!
Maybe a way around this situation would be for another frquency to be used for training fixes rather than 121.5. I'm sure the technology is there for D&D to still answer the call, but not have it broadcast on guard. We'd all be happy then.
Time to go flying, I'll try not to get lost!
