Food for thought
on speed
regardless of being anywhere on non radar environment time and distance calculations is based on that speed you filed. Saying there is no speed restriction is not so true. You are required to maintain your mach number during the crossing regardless of altitude on or of track and if you deviate you will have to inform the Gander or Shanwick (or New York os San Fransisco). And as you deviate in speed your next fix or expected fix arrival time will vary and if it is more then three minutes, you will have to advise also.
If you require speed change due to weather, turbulence you need to advice also, regardless of altitude, tracks etc.
It is good practice to plot on the crossing chart the tracks and their letter number even if you are above them. Your crossing flight might cross Tracks and know you know where to turn away from when you have a contingency at FL430. Also you can then find out how to descend latterly in between them as you know where you are on the crossing chart at all times. Right ?
Also you want to plot your ETP EPD for all three cases of you crossing.
THis gives you something to do during and prior to your coast out point.
