IAFs and FAFs?
Hi all, first posting this year, so here goes! I was wondering if one of you pro's could explain to me what and how and when Initial Approach Fixes and Final.A.Fs are used. (Esp. the what are they bit!)
Secondly, are there just the 4 IAFs at LHR? (BIG, EPM, BNN, LAM)?
And lastly, what does the circular symbol made up of 3 rings of "+" mean? like the Chiltern one near Bovingdon?
