When cleared to takeoff following the departure of a large aircraft, plan to become airborne prior to the point of rotation of the preceding aircraft and stay above the departure path or request a turn to avoid the departure path.  Landing:  When behind a large aircraft landing on the same runway, stay at or above the preceding aircraft's final approach flight path, note the touchdown point and land beyond this point if it is safe to do so.  ATC will use the words "CAUTION - WAKE TURBULENCE" to alert pilots to the possibility of wake turbulence.  It is the pilots' responsibility to adjust their operations and flight path to avoid wake turbulence.
