Thanks Guys for the info, Its amazing just how complicated it can be for the guys in the ATC, taking into the consideration the diffrent aircrafts ie; A380, followed by 737 or a330, 777 etc, do they give instructions about the wake and turbulance that follows the heavies ? does the horizontal seperation increase after a heavy ? also does ILS vary for heavies and say a 737 or m89 for example, since the gradient will be diffrent...
Also while the aircraft is landing, I believe they are at maximum thrust..does that mean that the speed in reduced just with the help of airbrakes, aielrons and flaps ?
