Hello Blue Heeler, I've only recently gone back to using Jepp charts in which this 'Emergency Use Only' is stated. Previous IAL charts I have used (non Jepp.) have not had this restriction, or at least I can't remember it, and like I say, I've taken advantage of a lower MSA as a standard proceedure to facilitate entry into the IAL proceedure or even becoming visual at that lower MSA. However it IS on the glossary of the Jepp charts as a restriction. It's probably a factor that affects < 1% of IAL's but tossed in there to cover Jeppesen from a legal point, but seeings we use Jepp charts and this restriction covers all of them, I guess from that same legal viewpoint, I'm bound by it. It's dam anoying to have a practical application made illegal to satisfy a technicality. I can't see a way around it at the moment that gives me the option to legaly use it. Can you ?
