1. What makes a craft more “PPG” and less “PPC” (select all that apply)

A PPG motor generally has more power than a PPC motor.

A PPG motor generally has less power than a PPC motor.

A PPG controls the wing using hands while a PPC uses foot inputs.

A PPG uses a more elliptical wing than the squarish PPC wing.

A PPG is usually lighter in weight than a PPC.

2 / 17

2. On landing in moderate or stronger wind:

While the wing is up, there is a reasonable chance of rolling backwards or tipping over.

It's best to turn the cart sideways and bring the wing down downwind.

Bring the wing down upwind of the cart to avoid tipping over.

3 / 17

3. What are the top 2 causes of injuries with carts (select the top 2)?

Attempting to launch while the wing is oscillating.

Body contact with spinning prop.

Abnormal wing deflation during launch.

Cart “spinout” due to uneven liftoff.

Rolling over during launch or taxi.

4 / 17

4. During launch, you notice the wing is off-centered slightly to the right. What should you do?

Turn the wheel(s) of the cart slightly right to reduce the odds of tipping over.

Turn the wheel(s) of the cart slightly left to bring the wing back.

Apply full throttle to take off quickly before you tip.

Keep the cart straight and increase brake pressure.

5 / 17

5. Which statement is true regarding wheel launching in strong winds?

The heavier weight of the cart will prevent rolling backwards.

It is better not to have assistants pull the cart during inflation.

The cart is likely to roll backwards when the wing inflates.

You'll need to hold the A's longer during inflation.

6 / 17

6. Regarding takeoff distance using a cart:

Expect a longer takeoff roll compared to foot launching.

Expect a shorter takeoff roll compared to foot launching.

There should be no difference in takeoff ground roll/run distance.

The cart will have a shorter roll in no wind and a longer roll in high wind compared to foot launching.

7 / 17

7. On the takeoff roll, once the wing is fully centered overhead the pilot should:

Concentrate on steering with the nosewheel to stay under it

Concentrate on keeping the wing centered using the brakes with only minimal nose wheel steering

Keep significant brake applied to get weight off the wheels as much as possible

Use wheel steering input slightly opposite to the wing to bring it back overhead

8 / 17

8. In windy conditions (over about 10 mph), for unassisted launch and landing, carts are

Harder to manage

Easier to manage

About the same

9 / 17

9. Which statement is true regarding wheel launch vs foot launch?

Carts are less subject to pendular action.

Wheels render the need for an assisted launch unnecessary.

Wheels make it more difficult to launch in no wind.

Wheels make it easier to launch in no wind.

10 / 17

10. If a heavier pilot flies a machine (motor and wing) normally flown by a lighter pilot: (select all that apply)

You will require less speed to take off.

You will require more speed to take off.

If no adjustments are made, the machine will tend to fly more nose down.

If no adjustments are made, the machine will tend to fly more nose up.

The wing will be more dynamic due to heavier loading.

11 / 17

11. Regarding control during launch

It's better to minimize wheel steering input

It's better to primarily use wheel steering input

Only use wheel steering once the wing is up and overhead

Only use brake steering once the wing is up and overhead

12 / 17

12. On takeoff, best practice is to

Commit to only taxi power until the wing is stable and tracking with the cart, THEN apply more throttle for takeoff.

Commit to full power. As the wing comes overhead, dampen it, steer towards it, liftoff.

Hold full power. Do not steer the cart, let the wing stabilize overhead without using brakes.

Keep you hands up during the process and let the wing stabilize while holding full power through liftoff.

13 / 17

13. Refer to the illustration. Regarding “Thrust Line” (#8):

Having it up slightly helps keep prop blast from disturbing the wing.

Having it angled up makes the launch less efficient.

Having it angled up makes the acceleration slower.

14 / 17

14. #2 is showing the hook in points, there are 4 (represented by white circles with black numbers). Moving the attachment point forward from hole 3 to 2 (forward) will affect takeoff by:

Making the front wheel(s) come off earlier

Making the rear wheel(s) come off earlier

Have no effect on when the wheels come off

15 / 17

15. Number 3 is pointing to the A-assist. It should only pull on the A's until the wing is overhead. If it's not adjusted properly, what can happen? (select all that apply)

If it's too loose (long), it won't assist with inflation.

If it's too tight (short), it will over pull the A's and may cause a front tuck.

If it's too lose (long), it will make inflation easier.

If it's too tight (short), it will take longer for the wing to come up.

16 / 17

16. What does the A-Assist do on a cart? (Select all that apply)

Pulls the A riser all the way until liftoff.

Pulls the A riser until the wing comes overhead.

Acts as a speed bar and pulls the speed system until liftoff.

Acts as a speed system until the wing comes overhead.

17 / 17

17. The number 3 is pointing to a thin grey line. What is this grey line?

The A-assist

The Line holder

The wing helper

The riser holder
