Hi,
I use the full version of the PM Boeing-type suite. (GC, MCP, CDU).
I am having some problems with VNAV. (The first may not be a problem but the 2nd certainly is!).
On the 737NG, on take-off, if VNAV is engaged during the intial (V2+10) climbout, should the FD be commanding V2+10 upto the acceleration alt, then switching to 250kts pitch ?
I am finding that as soon as I engage VNAV, it goes to 250kts pitch climb.
Am I getting confused with the 767 and 747, and does the 737NG not provide V2+10 (or any climbout) as part of VNAV ?
My second issue is that occasionally, I will reach cruise but the VNAV cruise speed set sticks on 286 kts, and not the mach speed I have set in the VNAV CRZ page. (It is as if the VNAV thinks it's starting a descent as soon as cruise is reached!).
My 3rd issue is that VNAV will usually start to command a decent before the T/D point that is indicated on my ND. (Although the descent can be reasonably accurate so perhaps this is a CDU issue with the placement of the T/D psuedo waypoint?).
Thanks for any help!
