Hello,
I have stumbled upon an issue with the coupler radio selector switch for the autopilot in the arrow (both 3 and 4).
When switching the coupler to NAV2, nothing happens.
NAV1 works as it should, with the OBS working in both the VOR1/ILS indicator and in the HSI, and the autopilot responding accordingly.
My assumption is that when selecting NAV2 on the coupler radio selector switch, the radio signal from the NAV2 radio should be used by the autopilot, and visually checkable by looking and turning the OBS knob from the VOR2 indicator.
Am I right in thinking it should work this way, or is the NAV2 not capable of transmitting to the autopilot (since the HSI also only works with the NAV1 RADIO)?
Thanks in advance for shining a little light on this.
