How Well Do You Know Airplanes?

Explanation
An airplane typically has two wings. These wings are the main lifting surfaces of the aircraft and are positioned on either side of the fuselage. The wings generate lift by creating a pressure difference between the upper and lower surfaces, allowing the airplane to stay airborne. Having two wings also provides stability and maneuverability during flight.

Explanation
An airplane typically has six tires. This is because most airplanes have a landing gear configuration called a tricycle gear, which consists of a nose wheel and two main landing gear assemblies each with two tires. The nose wheel and main landing gear tires provide stability and support during takeoff, landing, and taxiing. Therefore, an airplane generally requires six tires for safe and efficient operation.

Explanation
The correct answer is "Cockpit" because it is the designated area in an aircraft where the pilot and co-pilot sit to operate and control the aircraft. It is a crucial part of the plane where the flight instruments, controls, and navigation systems are located. The cockpit provides a clear view of the outside surroundings and allows the pilots to communicate with air traffic control.

Explanation
Before landing, it is essential to put on a safety belt. This is because during the landing process, the aircraft may experience sudden movements or turbulence, which can pose a risk to passengers. Wearing a safety belt ensures that individuals are securely fastened to their seats, reducing the chances of injury in case of unexpected events. It is a standard safety measure that should be followed by all passengers on board.

Explanation
The correct answer is 15 minutes because oxygen masks on an airplane are designed to provide a limited supply of oxygen in case of an emergency. These masks are typically connected to a central oxygen supply system on the plane, which can provide oxygen for a specific duration. The duration is usually around 15 minutes, which should be enough time for the plane to descend to a lower altitude where the air is breathable. It is important for passengers to follow the instructions of the flight crew and put on their masks immediately in case of a depressurization event.

Explanation
The correct answer is 800km/hour because it is the only option that represents a high speed rate for an airplane. Airplanes are designed to travel at faster speeds compared to other modes of transportation, and 800km/hour is a typical cruising speed for commercial jetliners.

Explanation
A black box is a device that is used to record and store data about the activities and performance of an aircraft or any other vehicle. It is designed to be indestructible and can withstand extreme conditions, such as crashes or fires. The term "black box" refers to the fact that the device is usually black in color and is often the only thing that remains intact and recoverable after an accident. It plays a crucial role in accident investigations as it provides valuable information that helps in determining the cause of the incident.

Explanation
America has the most airplane crashes compared to the other countries listed. This could be due to a combination of factors such as the size of the country, the number of airports and flights, the complexity of the airspace, and the overall aviation infrastructure. Additionally, America has a high volume of air traffic, both domestic and international, which increases the likelihood of accidents. It is also worth noting that America has a large number of commercial airlines and private aircraft, which further contributes to the higher number of airplane crashes in the country.

Explanation
The correct answer is NASA X-43. The NASA X-43 is the fastest airplane in the world as of 2017. It holds the world record for the fastest speed ever recorded by an aircraft, reaching a top speed of approximately Mach 9.6, which is around 7,346 miles per hour. The X-43 is an experimental unmanned aircraft designed to test new technologies and push the boundaries of flight. It uses a scramjet engine, which allows it to achieve such incredible speeds.

Explanation
The correct answer is "Tyres" because an airplane moves on a runway using its wheels, which are commonly referred to as tyres. The tyres allow the airplane to roll along the ground and provide the necessary traction for takeoff, landing, and taxiing on the runway.
