Wake Turbulence Category in Taxi Call?
I was always of the understanding that "Heavy" or "Super" was required on first contact with approach, departures, director or tower (Jepp ATC AU-812). Somewhere along the way it has been determined that it shall also be included in the taxi call (interpretation of ATC AU-936). The wake category is shown in brackets, meaning it is optional and may be required in certain circumstances. I maintain that it is not normally required, and perhaps the statement refers to eg. situations where there is a single ground/ tower frequency.
Does anyone have further references regarding this? ATC - what do you want?
