"Hi" procedures are for military aircraft, primarily fighters. NACO
charts them when they are published for a civil airport. Jeppesen does not.

I stumbled on this chart while preparing for an upcoming flight to
Knoxville:

I see some unfamiliar graphics on this chart, namely the dotted lines in
both the profile and plan views, and the candy-striping at the top and
bottom of the page. I perused the legend at

http://www.naco.faa.gov/d-tpp/frntmatter.pdf

but don't see any description or explanation of these graphic elements.

The procedure is named "HI-ILS...". What is that? High altitude? High
speed? I notice that there are published transitions starting at 13000
feet, and also that there are minima listed for approach category E,
whereas most approaches seem to show only categories ABCD.

A PDF search of the AIM at http://www.faa.gov/ATPubs/AIM/AIM.pdf for the
string "HI-ILS" produced no hits.

A google search of rec.aviation.ifr produced some hits, including the
information that a HI-ILS approach is a military procedure, and noting
that "...the approaches in question are not published in the civil US
Terminal
Procedures Publications". I guess that's now changed.

So if these approaches are now published in the civil publications,
shouldn't the graphics be described in the corresponding legend
publication? Anyway, what is the significance of the candy stripes and
the dotted lines?

For reference, there is also a corresponding ILS approach to the same
runway:

Might I ever fly a HI-ILS approach in my Mooney?
