For years I have taught that the ILS G/S should be approached from below, to avoid the (first) false lobe. Now
this (page 16) indicates that some A/Ds have some procedure annotation indicating that it may be intercepted from above.
I know about CDAs and am not interested in them (helo ops). I really want to read the words so I can see exactly what is intended. I have asked on Tech Log, and I have contacted the publication's editor, but no-one can provide examples.
Can anyone here point me in the right direction? (That being an air trafficker's job, after all!) Otherwise this would appear to be an unsupported assertion.
