Knowing the limitations of your gear it may
still be beneficial to be able to compare two completely different
methods of computing the wind in a thermal for example.


I find this comparison quite beneficial - particularly on final glides
were a "second opinion" on required altitude gives me some comfort
that I am on track. I personally use a 302 with WinPilot and an
LX-7000 so I have two redundant systems with only the battery wiring
as a common failure mode. Normally I use WinPilot for task management
(except for a custom Glideplan map with all the turnpoints overlaid
promenently for use in picking MAT turnpoints so I can minimize screen-
poking time). The LX I use for a live list of the closest landable
spots (here I wish I could sort by arrival altitude rather than
distance because distance alone is an insufficient metric for
alternates in the mountains and I find myself comparing coser-in
alternates to find the one with the biggest margin - can you say
Hurricane Mesa?). On final glides I compare both instruments to ensure
against differences in wind calculations, or operator error. I
occasionally find a mis-set McCready value or wing loading this way.

I think the LX 5000/7000 series also pass TAS like the 302 - not that
it would help in Kirk's situation.
