777LR correct approach

[vertex75014 0]

Hi,

                    Flying since may month with 747 I decided to use now 777LR. but i experienced a trouble I can't reach (en descent programmed legs in FMC ) waypoints at correct altitude (in accordance with navigraph data) most of time the plane descent TOO slow ! I need use FLC and some time I go too fast ! in final I am too hight !

                     I am very surprised because this problem don't occur with the 747! Is something I didn't well?

                                                     

                         Other thing I seen after change transition altitude indication is first STD(2792) in green but after a fewminutes it pass in yellow (alert color   normally) what it's mean?          

                                                           

 Thank you for help

Fly the tutorial. It will teach you how to fly the aircraft properly.

Sounds like you're not using this function properly. See the above reference to the tutorial.

 

Full names - first and last - in the forum, please.

My first question is this - are you sure that it is descending in VNAV PTH mode or is it VNAV SPD mode?   The former will get you nicely on the right altitudes at the right points, the latter will mean that you are almost always too high!
