Traffic presents itself differently every day. Nearly 20 years under my belt and I have to say no two days are the same. If it was the same every day it would not take so long to train. By listening to an airband radio you only get a small part of the story.
Where I work , at Heathrow, yes you get the same aircraft day in and day out, but the traffic patterns are different. Factors like weather, lack of stands due outbound delays, airfield imposed restrictions like WIP , unsheduled closures, emergencies etc etc keep this job interesting. There are moments of relative quiet and there are moments when you are holding on by your proverbial finger nails. It is a brilliant job.
