Would it not either have to be at night or the met conditions precluding VMC to obtain the SVFR clearance in class D? You couldnt just ask for SVFR for the purpose of being seperated from others, right?
Anywhoo, im sure someone said on here that the withholding of IFR clearances (for ash purposes) for some reason encompasses SVFR clearances as well? Is that correct?
