It would be nice to fail each unit. However, a standard test is to fail
one screen at a time by dimming it to be unreadable.

That is failure #2 in my orgional post.
It dones not seem to be a realistic failure as all the information is still there,
just in a differnt spot. A simulated AHRS or Air Data failure would be
a more realistic senario.

Once in reversion
mode you can do anything on either screen. I'm not sure what you mean
by dimming the display leaves no source of nav info. You can still fly
GPS and ILS and VOR etc with a failure. There are two nav sources on
the plane (two nav radios), if you truely lost the left or right
computer you would still have nav #1 or nav #2 (depending on which side
failed) for VOR, ILS, etc. If the left side fails nav #1 and com #1 die
but you can still use nav #2 and com #2. If both sides die the radios
go to 121.5. The G1000 system has two GPSs on board and part of a
reasonable pre-takeoff checklist is to check the signal strength of
each. In revision mode you don't have a moving map but you can still
select "direct to", "vectors to the approach", "gps direct approach"
etc. Also, you do have your inset map, which is mostly the same as the
MFD map, just much smaller.
However, other than the display, the "main" computer and the GPSs there
is not much redudant in the G1000. For instance, if the Air Data
Computer were to fail, you would just get X's across the driven
instruments. However, that is why you have 3 round dials between the
screens.

1)Becoming instrument recurrent. (Steam guage airplanes)

2)Getting checked out in a G1000 182.

I'm planning to do the IPC in the Steam guage airplane with some additional instrument work in the G1000.


My real question is how would you do the partial panel approach part of an IPC in the G1000?

There are several ways I know of to simulate a failure on the G1000,
none of which allows one do do a partial panel approach:

1)Dim the display to the point of not being readable.
This leaves the backup instruments for aircraft control, but no source of nav infomation.
If your IPC partial panel approach is anything other than GPS you have no guidance at all.
If it is GPS then all you have is the moving map.


2)Dim the PFD display then switch to revisonary mode...
Just like flying with no failure only reading the instruments from the
co-pilot side. Good practice, but no where near as hard as flying a
partial panel approach with steam guages.


3)Pull the breakers for AHARS/ADC breakers, this simulates AHARS and ADC failures and leaves nav indicators,
but it kills Mode C so ATC is not happy.


For training purposes it would be real nice if you could articicially fail individual
parts of the G1000 AHRS, NAV1, air data etc...
