Need Help Setting up PM please!!
Hi guys, need to pick your brain a little here. I have setup the PM suite
Comp 1 = MCP
Comp 2 = overhead
Comp 3 = Capt PFD / ND. CDU
Using Pmfilecheck all is ok. Shared drives where it is suppose to be.
I downloaded the latest Airac files and seems to have updated in the cdu.
In the PFD.ini I set Type= CDU
I programmed the cdu as per normal. The preflight mode in the cdu.ini is set to off.
All way points are programmed and speed set.
This is the problem. As I takeoff and engaged the autopilot Lnav and Vnav all seem to be ok , ie climbing thrust N1 to to cruise level that I set to 15000. At my next waypoint I need to be about 9000 ft which is about 45nm away from my current position. I set my Altitude in the mcp to the next alt which is 9000. Suddenly the aircraft started a rapid descent and reached it in no time. Then I realise that it was flying without the Vnav from the fmc. In otherwords even with vnav and lnav engaged I can still control the aircraft altitude with the mcp as if it was flying without the cdu.
Lnav seems to be working fine however.
Has anybody come accross this or am I just stuffing something up somewhere.
I checked pmfilecheck and everything is still connected!!. Waypoints are also displayed on the ND!!
Thanks in advance
