Chapter 2.9 - Exam Review

Question 1

The turbulence generated by large Aircraft as a by-product of Lift called (Thrust Stream Turbulence/Wake Turbulence)?

Answer 1

Wake Turbulence.

Question 2

The strong, turbulent downdraft generated by the blades of a hovering Helicopter is called (Wake Turbulence/Rotor Downwash)?

Answer 2

Rotor Downwash.

Question 3

What area below a hovering Helicopter should be avoided by Pilots of Light Aircraft?

Answer 3

Three times the radius of the rotor diameter.

Question 4

What type of structural damage can be caused to Light Aircrafts which taxi underneath a hovering Helicopter?

Answer 4

Control Surfaces.

Question 5

Structural damage is more likely to be suffered by Light Aircraft’s after an encounter with (Wake Turbulence/Thrust Stream Turbulence)?

Answer 5

Thrust Stream Turbulence

Question 6

What is the primary control hazard for Light Aircraft’s as a result of Vortex encounter?

Answer 6

Induced Roll.

Question 7

The Stall IAS of an Aircraft is (increased/decreased) by any structural damage to a Wing?

Answer 7

Increased.

Question 8

The (further/closer) behind the source of jet blast and the (more/less) power added by the generating jet, the stronger the thrust stream turbulence?

Answer 8

• Closer.

- More.

Question 9

The strongest Vortices are generated by large, heavy Aircraft (just after rotation/prior to rotation)?

Answer 9

Just after rotation.

Question 10

When taking off behind a large Aircraft, departing Aircraft on the same runway, a smaller Aircraft should lift off (prior to/just past) the larger Aircraft’s rotation point and climb (above/below) its climb path?

Answer 10

• Prior to.

- Above.

Question 11

When landing behind a large Aircraft which has just landed on the same runway, Pilots of smaller Aircraft should stay (above/below) the larger Aircraft’s final approach path and land (before/beyond) its touchdown point?

Answer 11

• Above.

- Beyond.

Question 12

What action should the Pilot of a smaller Aircraft take to avoid the wake turbulence from a large Aircraft in cruising flight?

Answer 12

Fly above the preceding Aircraft’s flight path

Question 13

Why is it better for light Aircraft to delay their takeoff after the departure of a medium or large Aircraft (operating at low takeoff weights) from the same runway (2)?

Answer 13

• Fly above and offset the preceding Aircraft’s flight path.

- Fly 1000 ft below flight path.

Question 14

Why is it better for light Aircraft to delay their takeoff after the departure of a medium or large Aircraft (operating at low takeoff weights) from the same runway?

Answer 14

Smaller Aircraft might not be able to out climb the flight path and will encounter wake turbulence.

Question 15

Vortices tend to remain strong and within the touchdown or takeoff areas for a longer period (in strong crosswind conditions/on days with a 2 to 3 knots crosswind)?

Answer 15

On days with a 2 to 3 knots crosswind.

Question 16

Light crosswinds (can/cannot) cause vortex drift onto a parallel runway?

Answer 16

Can.

Question 17

Although the Vortices in the touchdown and takeoff areas remain strong in nil wind conditions, extreme caution is also required during takeoff and landing in (strong tailwinds/light quartering tailings) in order to avoid wake turbulence?

Answer 17

Light quartering tailings.

Question 18

The strongest wingtip Vortices are generated by heavy, slow Aircraft with (Flaps Up/Flaps Down)?

Answer 18

Flaps Up (clean).

Question 19

Although hovering Helicopters generate a turbulent rotor downwash, it is also possible for the blades to produce (Thrust Stream Turbulence/Wake Turbulence) when the Helicopter is in forward flight?

Answer 19

Wake Turbulence.

Question 20

When landing behind a larger Aircraft whose approach path (as it approaches to land on an adjacent runway) will be crossed by your Aircraft, what is the correct procedure to avoid the wake of the larger Aircraft?

Answer 20

Note touchdown point and land before it.

Question 21

When a Pilot accepts an ATC clearance to follow a large preceding Aircraft by maintaining visual contact, what is implied with regard to wake turbulence avoidance?

Answer 21

The pilot accept the responsibility of separation and wake turbulence avoidance.
