Key Takeaways:
- The FAA's Advisory Circular (AC) 90-23G on wake turbulence states that encounters are not always hazardous, with severity depending on factors like encounter direction, aircraft weights, and distance.
- The probability of induced roll increases significantly when an encountering aircraft's heading is generally aligned or parallel with the generating aircraft's flight path.
- Pilots are advised to avoid the area below and behind the generating aircraft, especially at low altitudes, due to the increased hazard of even momentary wake encounters.
- The current AC primarily addresses scenarios where an aircraft is below or behind a generating aircraft and does not explicitly cover crossing behind at the same altitude, an area expected for future revisions.
