Ugh.  There must be something I'm missing that is making this 250 k speed restriction not work.  

I am using the TOGA switches on the throttle to get going.  I have the speed window set up to 250.  I have the AT armed.  I have the ALT set to fl 280.  Heading window has the heading dialed up.  F/D is on, with only VNAV activated.  

TOGA, rotate at VR, gear up at positive climb rate. Hold speed to about 180 k with pitch manually.  Engage AP,  retract flaps, watch plane accelerate to about 270k at VS of over 5000ftm.  Even after climb mode activates, "TOGA" is still on the screen above the main flight instruments.  

What is truly messed up is that even after 10,000 feet, where the restriction should go away, the speed stays at 270 at 4000+ fpm climb.  Why would it do that?  It ought to lower the nose and accelerate to the 315 that is in the Legs page at 10,000, yes????


Is there something I am supposed to do to tell the thing we are not taking off anymore and that it should be thinking climb speeds?

EDIT ######I might have got it#############

Instead of using the throttle TOAG button, I used the continuous thust button on the glareshield right below the AT arm switches.  This time it did what I wanted it to do.  

I also changes my cost factor to 500 from 100, and it seems to have stopped altering my legs page after takeoff.

What does everyone else use for cost factor?


****EDIT #2 ******************!!!!!
It only switches from TOGA mode to VNAV Speed hold mode if LNAV is also selected!!  

AHA!!  I knew I was missing something.  If I only have VNAV selected, it never gets out of TOGA mode.  

That's a major bug, I think.   You shoukd be able to use heading mode to hold the runway heading until ATC turns you.  But if you use heading mode for lateral guidance and have VNAV selected for vertical guidance, it fails to follow the 250 k speed restriction.  As soon as I hit LNAV, the VNAV starts working properly!
