The box checks gps altitude vs the encoder altitude for sanity.
All the King boxes do this. So you will probably have to enter
the altimeter setting to get the approach to go active.

The 94 is a very nice box; many features of the 430s at a lower
price. Includes ILS approach guidance.

To bad there's no way to drop it in a 90B slot!

I'm learning to use the KLN94 IFR GPS and was wondering about using
the ALT button to set the current altimeter setting. I can see why it
would use this for VNAV, but is it required to set it for normal non-
precision approaches? I think the only thing I've read in the manual
so far was it helps to get the RAIM check done faster or something
like that.




I thought the 90B would drop in to the 89B and the 94 would do the same.
Bummer....
