IFR Piglet - modern ILS are self monitoring and they switch themselves off if there is any degradation of the signal. There will be a panel of lights in ATC that highlights if any of the elements are misbehaving but the old adage of 'if it doesn't code, don't use it' applies.
Moderator - I won't respond to Tourist's post despite its tone in an effort to avoid being yellow carded
However, I seem to have been flying where and when I was told for the last 31 years, so I think my taking of the Queen's shilling has been vindicated
TC - the funny thing about using the ILS was doing it VFR - why? And if you are doing it single pilot, who is doing the lookout???
