2. Landing Gear
What are three advantages of a tricycle landing gear over a tail-wheel type landing gear?

3. Landing Gear
It allows more forceful application of the brakes without the danger of nosing the aircraft over
It permits better visibility for the pilot during ground operations

4. Landing Gear
It prevents the tendency for the aircraft to ground loop.

5. Landing Gear
What is the name of the landing gear that has more than two wheels mounted on a single strut?
A bogie landing gear

6. Landing Gear
What is the function of the drag strut in a retractable landing gear?

7. Landing Gear
The drag strut braces the landing gear against fore-and-aft movement of the wheel, and it hinges in its middle to allow the landing gear to be retracted into the aircraft structure.

8. Landing Gear
What are the two most commonly used methods of actuating a retractable landing gear?
Electric Motor
Hydraulic Cylinder

9. Landing Gear Gear Position Indicators Red light
One or three green lights
Press to test

10. Landing Gear
What are four methods of emergency extension of a retractable landing gear?

11. Landing Gear Hand crank
Designed so it will free fall and lock down mechanically
Hydraulic pressure can be built up by a hand pump

12. Landing Gear
Actuated with compressed air from a storage cylinder

13. Landing Gear Maximum landing gear extended speed VLE
Maximum landing gear operating speed VLO

14. Landing Gear
What is the commonly used name for the landing gear safety switch that is located on the torque links?
A squat switch

15. Landing Gear
Explain when you would retract the gear after takeoff?

16. Landing Gear Explain when you would retract the gear after takeoff?
Two positive rates of climb and once there is no more runway available for landing in front of the airplane

17. Landing Gear
What is the function of the warning horn in a retractable landing gear system?

18. Landing Gear
The horn sounds to warn the pilot that the throttles are closed to the position for landing of the aircraft if the landing gear is not down and locked. It is different from the stall warning horn.

19. Landing Gear
How is nosewheel steering accomplished on a light aircraft?

20. Landing Gear
Most light aircraft have some form of direct linkage between the nose-wheel and the rudder pedals that allow the nose-wheel to be steered when the aircraft is on the ground.

21. Landing Gear
How is nose-wheel steering accomplished on a heavy aircraft?

22. Landing Gear
The nose-wheels of most heavy aircraft are steered with hydraulic actuators that are controlled by moving a small wheel that is turned by the pilot.

23. Landing Gear
What is the function of the shimmy damper that is used on a tricycle landing gear?

24. Landing Gear
The shimmy damper restrains the movement of the nose-wheel. It allows the wheel to be steered by moving it slowly, but does not allow the wheel to move back and forth rapidly.

25. Landing Gear
Why do modern high-performance aircraft use several small wheels rather than fewer large wheels on their landing gear?

26. Landing Gear
Small wheels spread the weight of the aircraft over a larger area
Several smaller wheels give a margin of safety in case one tire should fail

27. Landing Gear
Small wheels and tires are easier to house in the aircraft structure than large ones

28. Landing Gear
What is indicated by a tire wearing on the shoulder of the tread more that in the center of the tread?

29. Landing Gear
What is indicated by a tire wearing on the shoulder of the tread more that in the center of the tread?
The tire has been operated under-inflated

30. Landing Gear
How soon after landing should aircraft tires be checked for proper inflation?

31. Landing Gear
No sooner that two hours after the aircraft has landed. The correct inflation pressure in a tire is the pressure when the tire is cold.

32. Landing Gear
Why is it important that the tread of a tire not be allowed to wear to the point that water cannot pass under the tire?

33. Landing Gear
If water cannot pass under the tire, the airplane is likely to hydroplane or skid on wet runways?

34. Landing Gear
What is one of the main dangers of operating a tubeless tire in an underinflated condition?

35. Landing Gear
When the tire is operated in an underinflated condition, the cords flex and generate enough heat to damage the tire.
