Notes in what context (What kind of notes)?
As I fly exclusively on VATSIM I use a pre-made sheet that prints out and fits on my kneeboard (which is mounted to a board on my chair that I use for my flight stick as well.
I also print the first 3-4 pages of my OFP from the VA as it has all the performance data, etc… and I’d rather work off paper then flipping screens.
The VA has an VACARS program that logs / tracks everything.
I also export that to Excel for easier sorting
Then of course there is Volanta!
LittleNavMap keeps track of everything as well, and SimBrief. Navigraph Charts 8 also lets you keep your FP’s in there.
Between all those tools, I guess it does everything needed.
