More info?)
First thing to remember is that the BC button affects Flight Director (where
available) and autopilot only! It is common practise to set the course to
"front beam inbound course" which means the course of the main beam (usually
an ILS) e.g. if the ILS reads 156° then the back course would be it's
reciprocal 336° So even to fly the back course you would set 156°. If you
have a TDI only (the thing with the dial ring around) the needle deflection
will be reversed in any case. On a HSI however if you set the front beam
inbound course you will have correct left/right indication. The needle will
then point to the bottom when established on the back course.
Any more confusion to cause? ;-))))
