Gatwick is a busy single runway airport.Arrivals are straight forward with only usually one altitude restriction in the descent(13000ft at GWC) though you might get another higher restriction if arriving from the north or west.You are speed controlled by the approach controller and are expected to do a cda.Winds out of the southwest cause a little bit of turbulence on short final but they are not as bad since some buildings were removed.Expect late landing clearances if they are busy.The runway has some special lighting to give you some idea about distance to the runway turnoffs.Once you have landed vacate onto the parallel taxiway, do not stop on the runway.Taxi-ing is easy,follow the greens(lights).Turn your tcas to transponder only as you vacate the runway and select code 1000 before turning it off.
Departure-call the clearance delivery not sooner than 30 mins before your eobt.When ready for start turn your transponder on.Gatwick can get busy at certain times.I have spent almost 40 minutes at the hold more than once.
Sids usually turn into a radar heading shortly after being handed off to London centre. If you end up departing off 08R and are going west the turn is quite tight and speed needs to be no more than about 210kt unless you want to end up over South London.The same also applies if departing 26L and going north over London.Speed control is mandatory unless you need to go faster for aircraft performance.
Enjoy your visit.
