Default Microwave Landing System

I have never actually flown or seen one of these but I'm working on the CFII and have a question about it: in 1-1-11 it says that "both lateral and vertical guidance may be displayed on conventional course deviation indicators..." so does that mean a non MLS-equipped aircraft could tune in the MLS frequency and fly it as long as it has "conventional course deviation indicators" (which I'm assuming is just a VOR with localizer and glide slope needles)?

I know this is not a very exciting topic to waste your days off talking about but thanks for any help!

Never mind. The aircraft does have to have a microwave receiver (diff spectrum band than Very High Frequency).

No...and that question, and others like it, ought to be taken out of the syllabus / question bank. The chances are slim (and getting slimmer) and NONE that you will ever see a MLS here in the states. I'm pretty sure that the only one operating in the US is at Charleston Aux Field.

Does anyone know of any other MLS approaches out there?

NASA used a type of MLS to land the shuttle, with a glide slope inclined at 19 degrees.

Pope AFB had one at least at one time, and like was said, North Aux 15 SE of CAE has an MLS.

I seem to remember PDX had one, but I haven't seen the full chart set in several years. Not in my company issued set.
