Subject: Re: [LML] Re: Navigating in the IFR system in an experimental aircraft

Scott,
   You are right in the fact that you can only go direct in a radar environ=
ment.  There are no ways around it.  If you are flying direct using anythin=
g other than ground based navigation such as VOR's, and are outside navaid =
limitations, etc, you must be in radar contact in order to fly direct.  The=
re are areas out here in CO that there is no radar coverage below about FL1=
90, so even if you are way up there (at least way up for a Lancair), you ca=
nnot go direct unless you are direct to a VOR and within navaid limitations=
.  I say there is no way to do this, but there is one way and that is to go=
 OTP.  In that case ATC is not required to separate you from other aircraft=
 and therefor you can go direct even in a non radar environment.   All of t=
hese rules are way out of date.  Just another FYI, I'll bet there are a bun=
ch of you out there flying in the IFR environment using GPS that do not hav=
e the required documentation from the local FSDO.  You cannot fly legally w=
ithout this paperwork, and also includes a POH suplement.  I give WINGS sem=
inars on this subject all over the Mountain states, and can elaborate more =
if there is interest.=20=20
