My advice for avoiding wake turb - use with caution
Fly 0.5 NM laterally offset from the preceding (same as wake turb separation standard) until you are either:
- 5NM behind Medium or 6NM behind Heavy (not sure how you are going to tell that in a non radar environment), or
- above the flight path taken by the Medium or Heavy and land beyond it's touchdown point.
Feel free to shoot me down in flames.
