Well, okay, but I work with this stuff all the time.


That doesn't mean you understand it.



Here is from the current FAA Order 8260.19C:

l. Dual Minimums. Enter dual minimums, when authorized. Do not publish
dual minimums unless a 60-foot operational advantage is obtained or a
reduction in visibility can be achieved. To avoid proliferation of dual
minimums, *all IFR aircraft are assumed to have at least one VOR
receiver*. Dual minimums based on a stepdown fix combined with local and
remote altimeter settings could result in four sets of minimums. When two
remote sources are used, treat the source resulting in lower minimums as
the "LOCAL" altimeter setting source in the following paragraphs.
Document only two sets of minimums. The combinations authorized are
minimums with and without a stepdown fix; or minimums with local and
remote altimeter settings.

The words between the asteriks are reflective of FAA Class I navigation
policy, which is a requirement to be a part of ICAO.


FAA Order 8260.19C places no regulatory requirements upon pilots or the
operation of aircraft.

How are you doing with that reference for the timing tables on NACO charts
being IAS?
