The Cessna 120-140 Association Forum

I know it sounds crazy in the age of GPS, but as some may know, DME is still required when flying IFR in Europe. I try to covert a 140 into an IFR trainer and are therefore intending to install a DME. Is there anybody who has a DME in the panel of a 140?
Thank you for your help!

Does European IFR require a separate DME radio or can the DME function be incorporated in a panel mounted GPS like a Garmin 430 for example. I've routinely used a 430 as (4) four different radios in one. (1) Communications, (2) VOR/ILS, (3) GPS, and (4) DME.

Good point! Thank you for your comment. The DME function is legally sufficient. An integration with e. g. a GNS-430 which sets the frequency (by selecting a VOR or ILS frequency) and shows the DME value, is possibility and saves some display space.

If it does not need to have actual DME and can substitute GPS position for distances the slim 175/335/375 navigators could be a good choice. Have a 175 in a 120 and works well. No ILS though so if that’s needed the GTN650 would be a good choice. Plus it can control a remote txp saving more space.

Yes a KNS80, kind of outdated but works great and no subscription services required.
