BOAC:
- have I not just done exactly that? I am unconvinced that just because it 'fits' with some notion of naming in TERPS that it is correct!
No, you have not. You are presuming an HSI where the card is rotated (thus changing the orientation of the CDI) by changing the value in the course window; i.e., set the inbound front course to have to-the-needle sensing on a back course.
Fix cards cannot be rotated. That is the purpose of my illustration above. This installation at ASE was done many years ago, to accommodate the lowest common denominator. There was, and is, no "notion of naming in TERPs" that drove this installation.
