5 RINGS.....
First of all, VFR flights are allowed to small crafts....and is very common in LGGG.
I dont know, if you chaps from UK know how a plane flies without the usage of FMC's, FMGS, MCDU's and all that crap, but once I gave the opportunity to a fellow chap from UK, to make a visual approach in LGIR, and he lost himself ....Actually, new "era" teaches "computer and panel operators", the old era, as I am, was teaching real aviators...
According to the capt. who did this, I know also a brit, cpt, who miscalculate the hdwind, coming inbound to LHR, and he miss the runway, for a couple of hundred yards, due to fuel starvation...
This same day I was also inbound to LHR, with A340, and had 2,5 tons more fuel on board for hdw....
I was "lucky" and landed a few minutes earlier, with some fuel in my tanks...
