Descent When Cleared For Approach
A question for those who know everything:
You are established on LOC after a radar vector, maintaining 4000ft.
The published procedure shows the whole approach at an altitude of 2500 ft, and a glide intercept at that altitude.
The controller than says you are cleared for the approach: are we obliged to capture the glide at 4000ft, or can we take the initiative to descend at 2500ft, then capture the glideslope?
All minima are satisfied in my scenario (MSA, Radar Minima, Approach Plate Minima etc...): I'm asking about the initiative to descend to a lower altitude when cleared for the approach.
Thank you for your help.
