3.6: Wake Turbulence Flashcards
Wingtip vortices created by large aircraft tend to
sink below the aircraft generating turbulence.
Wingtip vortices are created only when an aircraft is
developing lift
(Refer to figure 48) with winds reported as from 300 degrees at 4kts, you are given instructions to taxi to runway 30 for departure and to expect to takeoff after an airline, which is departing from runway 35L. What effect would you expect from the airliner’s vortices?
The winds will push the vortices into your takeoff path.
When taking off or landing at an airport where heavy aircraft are operating, one should be particularly alert to the hazards of wingtip vortices because this turbulence tends to
sink into the flightpath of aircraft operating below the aircraft generating the turbulence.
When landing behind a large aircraft, the pilot should avoid wake turbulence by staying
above the large aircraft’s final approach path and landing beyond the large aircraft’s touchdown point.
The wind condition that requires maximum caution when avoiding wake turbulence on landing is a
light, quartering tailwind.
How does the wake turbulence vortex circulate around each wingtip?
Outward, upward, and around each tip.
When landing behind a large aircraft, which procedure should be followed for vortex avoidance?
Stay above it final approach flightpath all the way to touchdown.
The greatest vortex strength occurs when the generating aircraft is
heavy, clean, and slow.
When departing behind a heavy aircraft, the pilot should avoid wake turbulence by maneuvering the aircraft
above and upwind from the heavy aircraft.
Your flight takes you in the path of a large aircraft. In order to avoid the vortices you should fly
above the flight path of the large aircraft.
