I have seen nothing in the SOPs that suggest visual approach requirements are stricter than JAR Ops. The company culture seems to be 'don't do em'. An example is another SFO (from the same background as I) recently turned off the automatics as opposed to button pushing at low level and completed a visual right base and landing rather than an ILS (in CAVOK) and was complemented by the Captain...as if what he did was quite unusual. He just figured it was a normal approach and was quite surprised at the reaction. Along the lines of the DXB example earlier in the thread.
I'm not suggesting visuals in marginal VMC or busy airspace, LHR for example, but there are plenty of opportunities in our operation to do them both at our home base, it's virtually our own private field, and various destos on our network.
Surely the ability to eyeball an approach, backed up with a rough idea of track miles to run & altitude/speed to lose is a fundamental skill set all pilots need to know?
