ok tnxs 'Rudd' I guess that means seeing as we are now in heading mode Alt constraints would normally only be associated with a pre installed flt pln in the MCDU right? I Imagine that any ALT constraints that need to be considered (from the previous flt pln route) would have to be manually selected by the pilot on the FCU? That's the way I am forming a picture here with all this.
If the Lat nav is then reset to managed as in back towards the flt pln does the OP CLB revert back to managed CLB automatically?
All fascinating stuff, yeah I know I gotta get a life right?
Well am about to undertake a 'bus' course & so far this pre study stuff I've been doing has left me with a head full of stuff that would choke a brown dog!
