Hello LML'rs,

=20

I am flying off the last few hours of my Phase I program on my IVP and =
this
weekend I was about one hour into a flight when the Cheltons produced the
RED X of death on the PFD screen.  Of course Bitchin' Betty put in her =
$.02
as well and she has been reminding me ever since.  Have tried rebooting =
and
turning off/on EAU, AHRS etc to no avail for about five hours of flight =
time
now. =20

=20

Have Crossbow 500.  Anyone have suggestions for troubleshooting and
correcting? =20


When I was doing  ground runs last year and taxiing around etc, I would
notice frequent but apparently random incidences of this failure as well =
as
GPS failures, shut down and rebooting of one or both of the IDU's and so =
on,
but since we've been flying, I had not seen this type of anomaly occur.

Regards,
