Questions and Answers

Why do all jet aircraft have a nose wheel landing gear instead of a tail wheel landing gear?

Nose wheel landing gear is easier to manufacture.

Tail wheel landing gear provides better maneuverability.

Nose wheel landing gear allows for faster landings.

Directional stability is required for take off and landing. (correct)

What is a consequence of having a tail wheel landing gear?

It enhances the aircraft's stability during landing.

The aircraft can easily pivot around the nose wheel.

The center of gravity is located forward of the main wheels.

The center of gravity is typically aft of the main wheels. (correct)

Which of the following statements about nose wheel and tail wheel landing gear is true?

Tail wheel landing gear is preferred for high-speed take off.

Nose wheel landing gear improves directional stability during landing. (correct)

Nose wheel landing gear has less impact on aircraft design.

Tail wheel landing gear is more common in modern jet aircraft.

Study Notes

Directional Stability in Aircraft

Directional stability is crucial during take-off and landing.
Aircraft with tail wheel landing gear have their center of gravity located behind the main wheels. This means that the friction generated by the main wheels during landing is behind the center of gravity.
This configuration results in a nose-down moment, which can lead to instability and loss of control.
To overcome this, all jet aircraft are equipped with a nose wheel landing gear. The nose wheel is located in front of the center of gravity.
This configuration shifts the main friction point forward of the center of gravity, ensuring a stable landing with a nose-up moment.
