CTO CTO Wake Turbulence & Separation Standards

Question 1

Wake turbulence is primarily caused by which aerodynamic phenomenon?

Accepted Answer

Wing-tip vortices generated by lift

Answer

Engine exhaust thrust

Answer

Propeller wash at low altitude

Answer

Airframe drag during descent

Question 2

Under FAA Order 7110.65, which aircraft category requires the greatest wake turbulence separation when landing behind a Super (A380-class) aircraft?

Accepted Answer

Small

Answer

Heavy

Answer

Large

Answer

All categories equally

Question 3

Wake turbulence vortices from a departing aircraft tend to move in which direction relative to the runway centerline in calm wind conditions?

Accepted Answer

They sink and drift outward from the centerline

Answer

They rise above the departure path

Answer

They remain stationary on the centerline

Answer

They move upwind toward the threshold

Question 4

A controller issues a wind report showing a 5-knot tailwind. How does this affect wake turbulence hazard for landing aircraft?

Accepted Answer

It pushes vortices back over the runway threshold, increasing risk

Answer

It carries vortices away from the runway, reducing risk

Answer

Wind has no effect on vortex movement

Answer

It accelerates vortex dissipation immediately

Question 5

The FAA wake turbulence category 'Heavy' applies to aircraft with a maximum certificated takeoff weight of at least how many pounds?

Accepted Answer

255,000 lbs

Answer

100,000 lbs

Answer

300,000 lbs

Answer

41,000 lbs

Question 6

When a Heavy or Super aircraft is departing, controllers must append which word to the aircraft's callsign in all ATC communications?

Accepted Answer

HEAVY or SUPER

Answer

CAUTION

Answer

LARGE

Answer

WAKE
