Am I just being pedantic, to wonder why it is called a TMZ (Transponder Mandatory Zone) , when it can be entered without having a transponder?
The TMZs near Stansted justified the expression rather more, as I understand it, because the only exceptions are for people from local aerodromes with specifically defined procedures.
Or are the exceptions seen by the authorities to be similar in all these cases?
