Suggested Action
The Air Data/Fuel Flow source is not providing RS
232 data to the GPS.
If no source of RS-232 is interfaced, the receiver
input must be jumpered back to the RS-232 out-
put on KLN 89/89Bs and KLN 90/90A/90Bs.
If no source of RS-232 is interfaced to a KLN 900,
the configuration may be set up wrong.

This is a feature, not a system failure.
Turn to the OTH 3 or STA 5 page to perform a

This prediction can also be performed prior to de-
