Question about certain parameters on FMC

[lineman55]

Im just an advid 737 sim pilot and really love this aircraft.Amazing work you certainly have put into it..but my question is ..
to get the TOGA to display on the FMS on roll out ..I even tried just the HEADING sel and got it to display on both at different times and now I cant it to display.Just N1 lights up.
I was wondering if certain parameters being set in the FMC determines if this will go active or not when I push the TOGA after N1 spools to above 40%..?   is there something im not checking off or a specific temp setting that I am ignoring that can cause this? climb rate? .. 

on another note when In flight and I decide to change spd/alt on a specific leg  the VNAV does no longer react...I end up using level change and V/S and dial down my speed to achieve requested alt /speed.Is this normal for the VNAV to ignore? other then that If I don't change anything the VNAV works completely.

Thanks for such an amazing aircraft!

Thanks for the nice words.

The most common mistake for the TO/GA mode is to NOT switch on both FD´s. The Takeoff mode won´t work unless you do, the go-around mode will, though. (Even pop up the FD´s automatically if they are off).

VNAV is very flimsy, currently - it does not take changes or complex procedures well. So for now we recommend to use it with care, and revert to more basic modes if it doesn´t act like you expect. Which is exactly what you did, good piloting judgement displayed right there!!

We expect to give VNAV a thorough overhaul after the plane was made XP11 compliant. So a wild guess would be sometimes next summer...

Happy landings, Jan

Thankyou! I was going nuts trying to get the TOGA to show..I after so many trial and errors..I didnt know what else to do.. one time they worked...and then they didnt.
I have watched everyone of the videos made with this aircraft model and try to follow along..but sometimes certain procedures are mentioned so quickly I miss them all together..

and something as simple as that...yep..missed it..thank you again for responding.Now..off to a TOGA party!
