Haftanın İpucu-2 Wake Turbulence and Landing

[Apollo]

Geçen hafta Wake Turbulance in kalkışa etkisini konuştuk.

Şimdi de Wake Turbulance oluşabilecek bir durumda mesela heavy uçak arkasından bir meydana inişle ilgili fikirleriniz nelerdir?

1. Landing behind a large airplane - on the same runway. Stay at or above the large aircraft's approach flightpath - note its touchdown point - then land beyond that point.

2. Landing behind a large airplane - when a parallel runway is closer than 2,500 feet, consider possible drift of the vortices to the other runway. Stay at or above the large airplane's final approach path - note its touchdown point - then land beyond that point.

3. Landing behind a large airplane - on a crossing runway: cross above the large airplane's flightpath.

4. Landing behind a departing large airplane - on the same runway. Note the large airplane's rotation point - then land well prior to its rotation point.

5. Landing behind a departing large airplane - on a crossing runway. Note the large airplane's rotation point - if it is past the runway intersection - continue the approach but land prior to the intersection, avoiding flight below the large airplane's flightpath. Abandon the approach unless a landing is assured well before reaching the intersection.

6. Departing behind a large airplane: Note the large airplane's rotation point - then rotate prior to the large airplane's rotation point and continue to climb above and stay upwind of the large airplane's climbpath until turning clear of its wake. Avoid subsequent headings which will cross below and behind a large airplane. Be alert for any critical takeoff situation which could lead to a vortex encounter.

7. Intersection takeoff - on the same runway: Be alert to adjacent large airplane operations particularly upwind of your runway. If an intersection takeoff clearance is received, avoid subsequent headings which will cross below a large airplane's path.

8. Departing or landing after a large airplane executing a low missed approach or touch and go landing: Because vortices settle and move laterally near the ground, the vortex hazard may exist along the runway and in your flightpath after a large airplane has executed a low missed approach or a touch and go landing, particularly in light quartering wind conditions. The pilot should assure that an interval of at least 2 minutes has elapsed before takeoff or landing.



Mini Wind Tunnel
A home made mini wind tunnel, showing how the angle of the wing and the use of flaps affect wake turbulence, using string.


How Far Below?
A NASA study, investigating how far below an aircraft is affected by wake turbulence.


Simulated Wake Turbulence Landing
Simulation of an Air NZ aircraft landing in an area affected by wake turbulence. Normally air traffic control seperates aircraft so that wake turbulence wont affect each aircraft.


A380 Special Adaptation to reduce wake turbulence.
