This topic is running in Tech Log, but I feel that it's headed strongly in a CRM direction.
What I have gleaned from the good responses here is that each operator has a system, and so long as there is a GOOD system of SOPs in place making no ambiguity in the comprehension of a standard call and the procedures which will follow, then there is no problem. It doesn't matter if Stop, Halt, or Sheeyut is called, as long as it's a standard call which should elicit a standard response.
Also detectable in the responses is the old well worn "Only my airline does it the right way"....Yawn
