Slight thread drift, but I think that RT phraseology in general is becoming worse - myself included. I find that in certain parts of the world, it's too confusing for the controllers if you use the correct terms, so I abbreviate (mostly in the Indian region). But in other areas, you are expected to use the correct form.
So, when I'm on a flight that takes in Australian airspace (correct use) , Indian airspace (abbreviated), and Middle Eastern airspace (depends on the controller, but generally correct use), I just use the terminology that gets the job done with few corrections as possible. If I'm in any way unsure of the clearance or instruction, I'll always ask again.
Back to thread - I don't like 'fully ready' I'm either ready, or I'm not. Simple
