I flew today to try out some more approaches with the KLN94 and the
entire time I was getting "Altitude Fail" in the MSG area, which the
manual says will display "When the altitude input becomes invalid
during operation". If I remember correctly, I think I saw when
turning it on or setting the ALT that it wasn't receiving any altitude
input, so I pushed ALT and set the altimeter to the current setting.
It kept redisplaying though... am I doing something wrong, or is it
getting a bad input possibly?


I was told by one of the club CFIs that you need to have your transponder
set to Mode C for this feature to work. So, while on the ground prior
get turning on the transponder (to mode-C), I get the same thing.

Once I've turned on the mode-c, I no longer get the message.

Is it possible the message was originally received while you were on
the ground (before you turned on the mode-c) and you never cleared
the message?
