As promised in my last post here is a video taken on a flight recently across the Pacific, tracking to Honolulu (PHNL)
The inverted Magenta triangle is the aircraft's ground Track. (The direction of movement across the ground)
The Inverted white triangle is the heading (the direction the aircraft is physically pointing)
The little arrow pointing left with 75 is the actual wind speed and direction IE (75 <--)
You can see the heading of the aircraft is 242 degrees, but the ground track is 233 degrees,
This means there was 9 degrees of left drift.
Another relevant point is the upright white triangle at the top of the pitch ladder (under the AP1)
This is the electronic version of the Balance Ball and is actually a split triangle where the bottom half slides left and right if you are not flying in balance. You can see the aircraft is completely in balance during this video.
Other things of note, the Indicated airspeed is only 242 knots but the True airspeed is 485 knots (The difference is due to much thinner air at altitude)
You can also see another aircraft, 2000 feet below us and to the left on the TCAS (Traffic collision avoidance system) - its the blue icon with -20 beside it.
