frundsberger updating the sector information manual is a mammoth task and not one that we have time for, especially given all of the airspace and procedure changes that have gone on since we started updating the sim in June 2023. We did start work on an updated version but it is simply too big a job and we are only 3 people, each with our own vocational and domestic commitments. At the moment, therefore (regrettably) there won't be an update. You can, however, get sector information from numerous sources on the web. If there's anything specific that you'd like, drop us an email at hq@londoncontrol.com and we'll see what we can do.
