Non-precision!
The LDA/GS approach is non-precision ... to qualify as precision, an approach must have sufficiently sensitive lateral and vertical guidance (for this reason, an SDF with GS ... if there is such a thing ... would be non-precision as well ... signal width provides half the sensitivity of a localizer), and align the user with the runway w/in 2.5 degrees ... the 30 degrees alignment from a prior post differentiates between a straight-in and circling approach.
I've had this discussion a few times with a good friend of mine who is a DPE, as well as with SPMs from two different FSDOs, and the answer was unanimous.
Take a look at some specific IAPs and think this through ... good examples off the top of my head include the LDA/DME and Rosslyn LDA 19 approaches at DCA, the LDA 6 at ROA, and the LDAs to 12L and 30L at STL. By the way ... these are all installed for different reasons ... good teaching tools for CFIIs out there ... I used them all the time for instrument students.
Tailwinds, y'all ...
