November 24, 20187 yr I don’t know if this bug has always been present in the Falcon. I just spotted it tonight while flying Beta 3.4 in P3D 4.3 I noticed that when an ILS is tuned on either NAV 1 or NAV 2, the associated RMI needle turns to point at the physical location of the localizer transmitter. This is impossible, because a localizer signal (unlike a VOR) contains no phase modulation which would permit the RMI to resolve a bearing to it. An RMI needle will usually rotate to its normal “no signal” position (typically 90 degrees) when a localizer is tuned. If others are not seeing this, then perhaps it is related to the installation of the RXP GTN750, which I just purchased today.

Jim Barrett Jim, As I recall this has been a long standing bug in the sim(s) themselves. For example, try setting Nav2 to a localizer in the default Baron 58 and note the RMI needle.

It would make the process of setting up an ILS intercept easier - especially in an aircraft without a GPS or FMS-driven moving map.
