The weight of the aircraft

Question 7

A swirling Hermas off the wingtip trailing behind the aircraft

Answer 7

Wake vortex, wingtip vortices

Question 8

Vertices are generated when

Answer 8

Answer 13

300 feet to 500 feet,

500 to 1000’

Question 14

For landing aircraft, crosswinds of 1 to 5 knots tend to ______the lateral movement of one vortex while ______ the movement of the other

Answer 14

Stall

Increase

Question 15

The mechanical force a wake vortex has on an aircraft

Answer 15

Induced roll

Question 16

The ability of an aircraft to move around the longitudinal axis

Answer 16

Roll control

Question 17

That ability of an aircraft to counteract the affects of the role, counter control, is based on two things:

Answer 17

The wingspan of the aircraft, the counter control capability of the aircraft

Be in forward flight

Question 22

Jet engine exhaust, thrust stream turbulence

Answer 22

Jet blast

Question 23

Why is the controller not responsible for anticipating the existence or effects of wake turbulence

Answer 23

Because it is unpredictable
