The concept of DGA where you have a you beaut GPS accurate to 0.3 nm for your distance and then rely on a wandering ADF needle pointing to a station that may not be within the confines of the airport boundary always had me wondering "why?".
Wouldn't it be possible to create an "approach" that would take you to a cloudbreak altitude ..below the 10 mile MSA and close to the circling minima ...based on a GPS track. Sectorised DGA's were ok with an NDB ...what's so bad about the lateral tracking of a GPS?
I know circling approaches are fast becoming persona non grata amongst the heavy metal but a circuit sometimes can be the most efficient way to effect a landing
