I'm assuming you mean that they were white when navigating off of the GPS, or did you have an FMS in your 1900?

green data
 

onmost new aircraft there are difft colors to show what nav aid you are using on the lear jet 45 green data is raw data in and yellow is both people are getting there info from the same fms and mengnta is info from two differnt fms .so when you set up a dep. you set up the fms and fly the fms but if the box goes out you now can go to green data mode and fly the route useing cross ref.vors on route.remember the way we use to fly aircraft :eek:

No, we had the good old KLN90. We did glass have glass attitude indicator and DG with HSI.

It sounds like the person from the FAA needs to read the FAA publication "Aviation Instructors Handbook", specifically the part on not using vauge/confusing terms. I would have been torn apart by the FAA for using such a term on my CFI/CFII/MEI checkrides.
