Gentlemen, maybe you can help me to find out on which aircraft the following described Flight Director Indicator (ADI) as part of the Collins FD-108 system is installed:

Details:
Manufacturer: Rockwell Collins
Type: 329B-7
P/N 522-3122-012

On this indicator the LOC-indication is replaced by a "FAST-SLOW"-indicator and the GS-indication is replaced by the "RADALT"-indication.

I have not seen this type of indication before in comparison to the "usual" LOC- & GS-indications.
