Nurjo's Considered Comments...
Nurjo!
I don't believe you are really a pilot. Real pilots and ATC (see threads by ZRH and the easyJet and other pilots above) are true professionals who like to get pax to destinations on time, turn round on time and get out on time. When this doesn't work, they feel frustrated. This has nothing to do not being able to manipulate throttles and stick.
ZRH is a big mess for noise, terrain and political reasons. That it works at all is amazing. In an attempt to get "slugs"of aircraft in, ATC often requests highish speeds until a quite a late point. When someone behind gets close, they sometimes request an even later speed reduction point. If the pilots can manage this, they do, even though it means a lot of checks and chat late on in the approach, when things should ideally be settled and established. If they can't manage, ATC sometimes has no choice but to order a GA.
The terrain north of the field (Wannenberg) can cause the Mode 2C GPWS to come on in certain incomplete configurations if flying level at 4,000ft, adding to the stress. In IMC this requires a pull-up/ go-around. (Actually the Stadlerberg, closer in is not a problem and when Alitalia hit it they were following a defective GS indication and well below glide path.) One nice thing which can happen to you is a Swing Over from 14 ILS to RW 16 (as opposed to the dreadful SideStep the other way round) requiring disciplined visual flying and early corrections but saving up to eight minutes of taxy.
Once on the deck you taxy through a crossing maze of taxyways and opposing traffic and having turned round and prepared you take bets on how much slot delay you will get. It can be a lot, especially late in the evening, as Take Off traffic and Landing traffic vie for the same strip - from opposing directions! After take off, there is often a low level off due to the traffic situation and several frequency changes just as you are in cleanup/checklist work and anti-icing switching.
Go and have a look in ATC and you will soon see that those guys don't have it any better - restrictions due to all the above plus military traffic, gliders and light aircraft close by - also climbing/ descending traffic from Germany transiting through.
It has been getting tighter on all concerned for fifteen+ years now and I for one am heartily glad that it is no longer my home base, which it was for 25 years. Good luck to all concerned.
