Hi BEagle,
I'm not sure many readers of this forum will have access to Y channel GPS!
But it is time we left the middle ages WRTo NAVAIDS. My company have been cleared for Fully Managed Non Precision Approaches (GPS as well!) using a Nav system you will be familiar with. Watching the aircraft fly a perfect 3D NDB approach profile on autopilot is a thing of beauty, especially when the weather is bad, it's night and there's high ground nearby - and it's your third sector of the day. But this is using an FMC position from a triple IRS mix with GPS update. Still, we had to have the NDB needle selected on the Nav Display as we are using the NDB Jepp plate for reference! Although last week when flying into Guilin, I think the it was poining at a CB the one time I glanced at it. If ever faced with having to do an real NBD approach in those circumstances - it's time to divert!
