I was once told by some instructor at Manston that I should not have flown the ILS in there, because I was solo and the wx was not bad enough for an ILS.
Quite right too! If you wanted to fly a practice approach, you should have followed the law as stated in the ANO.
But why would anyone otherwise bug.ger about playing airliners on long ILS approaches when the weather is good enough to join visually?
