..yes, does anybody have experience with a 'true dme' input?
It has been a number of years and in older certified aircraft that still have a DME installed. With the WAAS GPS systems taking over here in the States we are seeing the NDB, DME, VOR, fading away here. I know they are still relied on in other parts of the world, but as time goes by I think you will like the space based navigation and it will be coming to you more and more.
Hope this helps, Yours, R.E.A. III #80888
Robert, this is not an answer to my question. There is no way to approve an aircraft for IFR ops without DME in my part of the world.. I am not in love with DME nor would I like to spend the money but currently there is no workaround. In Europe, for 90% of the ILS or VOR approaches a DME is required.
thanks,
Hello Igor,
There is no support for a separate DME radio in G3X.
This perhaps doesn't help you, but since 1998, the U.S. has allowed the use of TSO-C129/-C145/-C146 GPS in lieu of ADF and DME, as explained in AC 90-108, thus significantly lessening the need for ADF/DME support.
Many of the U.S. approaches still indicate "ADF required", but in most cases, GPS is allowed as a substitute.
Thanks,
Steve
Steve,
Europe is many years behind the US in this regard. In many countries there is no definitive guidance if GPS is, really, acceptable as an alternative to DME. In many cases there is (probably) no issue of using GPS instead of ADF - although many approaches still use an ADF for the missed (don't ask why ...). As I understand it the situation with DME is less clear. Also several approaches frig the DME range to read zero at the threshold - so GPS range to the DME beacon position is inaccurate.
To remain legal I think there is no option but to install a 2nd hand KN-62 or 64.
