Thanks. I am not disputing what you say but
this SID (Northolt Buzad 3X) finishes at Buzad at 5000ft. Assuming I have not had further climb by Buzad, is it anticipated that I will be using ground-based nav aids to navigate to the waypoints below FL095?
Because B-RNAV is mandatory above FL095, is it prohibited below?
Once I am above MSA is there anything preventing me from using FMS direct-to and flying LNAV?
It is because of these questions that I am looking for source documentation.
