Congratulations Dreamfleet on another excellent product. I downloaded the 727 last night and have been flying it all day today. Brings back many memories of time in a real 727 sim years ago.
For your consideration in a future version:
My understanding is that a real RMI instrument does not/can not display bearing information via the RMI needles when an ILS frequency is dialled up and received on the NAV radio - only VOR (& ADF) signals should be displayed.
In the current Dreamfleet 727, the RMI needles do appear to respond to an ILS signal - the RMI needles seem to display a bearing related to the position of the localiser. (Incidently, the instruments in a lot of other FS aircraft including the default Microsoft 737 behave in the same way.)
Since radio navigation is such an important part of flying the old 727, any improvements to the realism in that area would be geat.
