-when atc requests a speed reduction for traffic, you ignore it, and the next sector instructs you high speed to the loc (Rome Atc)
-when Atis (Fco) has two frequencies for 3 rwys. So if you don't want to listen to both, get the rwy in use from Atc then go to the appropriate Atis
-when you have to be released by handling before you can ask for engine start (still Fco)
-when "give way" becomes "let pass" (lassa passa') (Fco ground)
