Hello. I see there are lots of smart folks in this NG and I learn a lot
from you. I have a question that I sure someone can answer for me. I'm not
so knowledgeable about some of the GPS approach procedures. I was reviewing
the GPS 16L @ KHEF (Manassas VA) and am not sure which DH is applicable to
my flying. I am not sure why the difference in LPV DA; LNAV/VNAV DA; and,
LNAV MDA. I fly a PA28R with a Garmin 430. Which landing minimum would
apply to me? Could someone expound on what each minimum applies to and the
decision process for determining which one applies to a particular aircraft?
I believe it is usually different types of on board equipment that would be
the determining factor but I do not know what is required for each. So far,
I have not been able to locate any educational reading that would explain it
for me.
Thanks in advance for your helpful comments.
