So as you fine folks may already know, in our usual style of going completely overboard on the level of detail, a few weeks back I've implemented a custom VHF radio signal propagation model. This means, NAV radios (VOR, LOC, GS and DME) are all simulating things such as terrain masking, terrain diffraction, tropospheric scattering, etc. The underlying computational model is based on the NTIA Irregular Terrain Model (ITM), an industry-standard model used for things like radio tower planning. The simulation includes a built-in analytics display that allows you to check the terrain profile being used by the radio model (please note, the image below isn't hand-painted, it updates in real time as you fly): What's recently new is that I re-implemented the ADF and standalone DME radios as well. So the entire radio complement in the TBM is as follows: Two VOR/LOC/DME radio. One ADF radio One standalone DME radio That involved re-implementing all course deviation needles and the DME tuning pages on the PFD. All features of the real G1000 are simulated, even some of the more odd ones: ADF, ANT, ADF/BFO and ANT/BFO reception modes. This is reflected in the audio ID portion, including the continuous tone you hear in BFO mode when no ADF signal is being received. All DME tuning modes simulated, so NAV1 slaved, NAV2 slaved and HOLD. Allows for flying the more bizarre approaches, such as NDB/DME. Intercom audio routing from the radios is properly implemented, so NAV1 & NAV2 buttons route the audio ID for the NAV1/2 VOR/LOC portion, the DME button routes the standalone DME radio audio (including 1250 Hz square-wave tone, instead of 1kHz sine wave) and the ADF radio routes the ADF radio audio (including proper tone & background noise behavior depending on reception mode).

This has already been mentioned and we've found a few workarounds for it. We'll post something shortly.
