Hi Mark,
Thanks for your reply. Yes, on the over head panel I did turn the DNS power switch to off, and once I had my ILS dialed into to Nav 1 I turned the auto pilot from Nav to heading. And still no luck in getting the glideslope indicator to move from the bottom of the scale. Did you have a similar problem when using doppler?
I always use to auto pilot controll from shift + 5. Maybe I should take a look on the forward isle panel to make sure it's coinciding correctly?
