Look at TrainATI (Dave Stohr) or Scott IPC for international training, FSI also has courses, if you use them. No recommendation, but they are leaders.
- Must have 8.33 radio spacing for EU. Check your fit
- Yes, the Blue Spruce routes don't have an HF requirement, but there are gaps at F410 over the Davis Strait. ATC expects you to be out of contact for about 20 minutes
- Can you go Gander non-stop to Iceland? If not, consider the Greenland options very carefully.
- EU Ops are different, but you can get around in English pretty easily. I never found France to be difficult compared to Russia, it's NYC.
- Canaries are wonderful
