This continues to be a pain in the neck for me.
In a reply to my enquiry, and editor from Airservices told me making the index is a 'time consuming and manual process' as one reason they stopped doing it.
Airservices are obviously very concerned about wasting time.
Why then do I receive bucketloads of these useless little edits and re-phrasings of unimportant little tidbits with every update?
They had to go through the process of discussing, re-wording, typing, printing, packing and distributing thousands of these pages so that subscribers could take out the old one and insert the new.
What a stupid waste of time. Whoever is in charge of this is doing a rubbish job.
