Gliders Quiz

What are the two main types of gliders?

• Jet fighter and helicopter

• Sailplane and hang glider

• Motorized glider and paraglider

• Hot air balloon and biplane

Explain the principle of gliding in simple terms.

• Gliding is walking without legs.

• Gliding is driving without a car.

• Gliding is flying without an engine.

• Gliding is swimming without water.

Name three main parts of a glider.

• Cockpit, rudder, ailerons

• Wings, fuselage, and tail

• Tail rotor, stabilizer, elevator

• Engine, propeller, landing gear

Who is credited with the first successful glider flight in history?

• Sir George Cayley

• Amelia Earhart

• Orville Wright

• Leonardo da Vinci

What are the advantages of using gliders for transportation?

• Limited range, noisy, and difficult to control

• Expensive maintenance, slow speed, and high fuel consumption

• High operating costs, harmful to the environment, and need for constant engine power

• Low operating costs, environmental friendliness, and ability to soar without an engine.

What is the difference between a sailplane and a hang glider?

• A sailplane is a glider with an engine, while a hang glider is foot-launched with no engine.

• A sailplane has a flexible wing and is foot-launched, while a hang glider has a rigid wing and an engine.

• A sailplane is smaller in size compared to a hang glider, which is larger and has a rigid wing.

• A sailplane is a glider with a rigid wing and no engine, while a hang glider has a flexible wing and is foot-launched.

How does the shape of a glider's wings help in achieving lift?

• The shape of the wings creates a pressure difference, generating lift.

• The shape of the wings reduces air pressure, creating lift

• The shape of the wings increases weight, creating lift

• The wings' shape has no impact on achieving lift

What is the significance of the Wright brothers in the history of gliders?

• They were the first to build a glider with no wings

• They were the first to fly a glider using solar power

• They were the first to design a glider that could carry passengers

• They were the first to successfully design, build, and fly a powered aircraft

Explain the concept of 'thermal lift' in relation to gliding.

• Thermal lift is a type of engine used in gliders to gain altitude

• Thermal lift is a downward current of cold air that gliders avoid

• Thermal lift is a type of parachute used by gliders to descend

• Thermal lift is an upward current of warm air that can be used by gliders to gain altitude.

What safety measures should be taken when flying a glider?

• Checking weather conditions, ensuring proper training and certification, using safety equipment such as parachutes, and following standard operating procedures.

• Listening to loud music during the flight

• Wearing sunglasses and a hat

• Ignoring weather conditions and flying in any condition
