It is important to recognise that one of the more 'fragile' systems in aviation is the R/T voice connection between pilots and controllers. So much of what happens, in fast moving situations, relies on the correct understanding by pilots of the controller's instructions, and the correct understanding by controllers of the pilot's intentions. Think about it for a while.
In international operations this is particularly important and there have been many instances where miscommunications have led to accidents. It cannot be stressed too strongly that the ICAO recommendations should be followed - using the correct phraseology in the correct contexts.
This may sound pedantic but it is not - safety is involved. The use of phrases like "roll the trucks" may sound clever but it is not. It is merely puerile.
