Wake Turbulence Flashcards
AD controllers shall when applicable apply wake turbulence separation minima…. when responsibility rests with the Pilot advice…: aircraft if the expected occurrence of hazards caused by turbulent wake.
True or False.
True
In issuing clearance or instructions, controllers should take into account the hazards caused by jet blast and prop slipstream to:
3 things
Taxiing a/c
A/C taking off or landing (particularly when intersecting runways are being used) and
Vehicles and personnel operating on an AD
Define wake turbulence
The effect of the rotating air masses generated behind the wing tips of large jet a/c
Is wake vortex different to wake turbulence?
Yes
Define wake vortex
The nature of the air masses. A wingtip vortex can be similar to small tornadoes
What is the weight of a heavy wake category?
136,000kg or more
What is the maximum take off mass of a super?
560,000kg
The letter J is used and the expression of what Wake category?
SUPER
What is the MTOM for wake category Medium?
Less than 136,000kg and higher than 7,000kg
What is weight wake of a light wake turbulence?
7,000kg or less
Who is responsible for ensuring the spacing from a preceding aircraft of a heavier wake turbulence category is accepted?
The pilot in command
How many minutes should an arriving Medium be behind an arriving super?
3 minutes
For arriving aircraft a medium landing behind a heavy should be how many minutes behind?
2 minutes
For arriving aircraft a light landing behind a super should be how many minutes behind?
4 minutes
For arriving aircraft a light landing behind a heavy/Medium should be how many minutes behind?
3 minutes
There is no other information minima applicable between aircraft for tower purposes. There is only a need to advise “caution wake turbulence”. True or False?
True
If parallel runways are separated by less than ______ the Same wake turbulence as if off the same runway shall be applied. True or False?
760m
True
Crossing runways if: the projected flight path of the aircraft will cross the projected flight path of the first aircraft at the same altitude of less than 1,000ft. Will be applied as if they’re the same runway. True or False?
True
For parallel runways separated by more than 760 metre if projected flight path of the aircraft ahead (first)at the same altitude or less than 1,000ft below. It shall be applied as if it is the same runway. True or False?
True
On a Displaced landing threshold what separation is required between an arriving L/M and a departing heavy?
2 minutes
If the projected flight paths are expected to cross when operating on a runway with a displace threshold
On a displaced threshold what separation is required for a landing L aircraft and a departing M aircraft?
2 minutes
On a displaced threshold what separation is required for a landing L/M aircraft and a departing J aircraft?
3 minutes
On a displaced threshold runway what separation is required between a departing L/M aircraft and a landing H aircraft?
2 minutes
On a displaced threshold runway what separation is required between a departing L aircraft and a landing M aircraft?
2 minutes
On a displaced threshold runway what separation is required between a departing L/M aircraft and a landing J aircraft?
3 minutes
For opposite direction use of runway what separation should be applied between a L/M and a H?
2 minutes
For opposite direction use of runway what separation should be applied between a L and a M?
2 minutes
For opposite direction use of runway what separation should be applied between a L/M and a J?
3 minutes
When would the need to apply opposite direction separation apply?
(3 things)
1) Heavier aircraft doing Low/Missed approaches in opposite direction
2) Lighter aircraft using opposite direction for takeoff or landing
3) Lighter aircraft using opposite direction on parallel runway separated by less than 760m
A H is taking off behind a J what separation is required?
2 minutes
A L/M is taking off behind a H what separation is required?
2 minutes
A L is taking off behind a M what separation is required?
2 minutes
A L/M is taking off behind a J what separation is required?
3 minutes
On an intermediate part of the runway a H is departing behind a J. What separation is required?
3 minutes
On an intermediate part of the runway a L/M is departing behind a H. What separation is required?
3 minutes
On an intermediate part of the runway a L is departing behind a M. What separation is required?
