CULTURAL QA 06-2023-22A Q1 Why doairplanes put down the landing gear so early when landing?
A1 Vishnu Ravi, Studied Aerospace andAeronautical Engineering (Graduated 2015)Wed Enhancing the landing experience, airplanesstrategically lower their landing gear well in advance,setting the stage for a smooth and controlled descent onto the runway. Thiswell-coordinated maneuver involves the reduction of thrust and the introductionof drag using flaps, landing gear, or speed brakes. By deploying the landinggear between 1000-2000 feet, approximately 2-3 minutes before touchdown, pilotsensure a stabilized approach, instilling confidence in passengers. Moreover, the early deployment of the landing gearserves another purpose—it diminishes the unwanted clamor generated at higherspeeds.By promptly engaging this system, the aircraft effectively mitigates noisedisturbance, creating a more pleasant atmosphere for passengers throughout thelanding phase. In the rareoccurrence of an emergency, airplanes possess a failsafe mechanism known as theemergency extension system. In such situations, if the main power system fails,the landing gear is automatically lowered. Assisted by the airflow and aided byredundant hydraulic systems in larger aircraft, the gear is securely positionedin the down-and-locked configuration. In smaller aircraft, manual extensionsystems allow pilots to crank the landing gear into place, ensuring a reliablebackup system. Overall, the prudent practice of deploying thelanding gear early during landing not only guarantees a safe and stableapproach but also minimizes noise disturbances. Furthermore, thepresence of an emergency extension system provides an additional layer ofreassurance, emphasizing the commitment to passenger safety and comfort. Q2 What aresome mind blowing facts that most people don't know? A2 Fact sky Answered by Krishna Kamat 1h The first person tolook into space with a telescope was Galileo,nearly 400 years ago. Only 5% of theocean has been explored and charted by humans. The rest are still unknown. Jellyfish is an aquatic animal that does not contain abrain, heart, or lungs. Africa and Asia are home to nearly 90 percent of theworld's rural population. Indonesia is home to some of the shortest people inthe world. Glaciers and ice sheets hold about 69 percent of theworld's freshwater. Q3 Why isthe helicopter transmission tilted forward? A3 Erika Fernandez, Experience inAviation Field18h The helicopter transmission is tilted forward in order toprovide forward thrust. When the pilot moves thecyclic control stick forward, it causes the swashplate to tilt forward. Thistilts the rotor blades forward, which creates more lift at the front of thehelicopter and less lift at the back. This difference in lift causes thehelicopter to move forward. The amount of forward thrust that is generated depends onthe angle of the swashplate. The steeper the angle, themore forward thrust is generated. The transmission is tilted forward so thatthe swashplate can be tilted to a steeper angle without hitting the ground.Ifthe transmission was not tilted forward, the swashplate would not be able totilt to a steep enough angle to generate enough forward thrust. This would makeit difficult for the helicopter to move forward. Q4 Why doAmericans call a bathroom/toilet/WC/lavatory a restroom when it is not a roomfor resting? A4 Jonathan Trueman, Professionalscreen-and-copywriter, voice artist, Brit, knowledge addict.3y It’s a euphemism,intended to disguise the crudity of its actual purpose… just like all the otherterms cited in this question. Do you take a bath in there? Well, it isn’t a bathroom,then, is it? Do you ‘make yourtoilet’ in there - i.e., wash and make up your face and dress your hair? So it’s not a toilet, either. Do you storeanything in there? That means it’s not a closet, and thus not a water closet, and thus not a WC. Is its main function having a wash? Not a lavatory, in thatcase. You have to go to France, I believe, to find thisparticular spade called a spade: Q5 Are dryfruits as nutritious as fresh fruits? A5 Vaibhav Uikey, Health is Key ofEverything3h Dry fruits andfresh fruits have some differences in their nutritional composition due to theprocess of drying. Here are a few key points to consider: 1. Nutrient Concentration: Dry fruits are more concentrated in nutrients compared tofresh fruits because the water content is significantlyreduced during the drying process. This means that the vitamins, minerals, andantioxidants present in the fruit become more concentrated in the dried form. 2. Fiber Content: Both fresh fruits and dry fruits contain dietary fiber,which is important for digestive health. However, the water content of freshfruits contributes to their higher fiber content compared todry fruits. When fruits are dried, the fiber remains, but it becomes moreconcentrated. So, while dry fruits still provide fiber, they may contain morefiber per serving compared to fresh fruits. 3. Calorie Density: Dry fruits are more calorie-densethan fresh fruits because the removal of water results in a smaller and moreconcentrated product. This means that a smaller portion of dried fruit containsmore calories compared to a larger portion of fresh fruit. So, if you'rewatching your calorie intake, it's important to be mindful of portion sizeswhen consuming dry fruits. 4. Vitamin C: Vitamin C is an essential nutrient found in many freshfruits, particularly citrus fruits. The drying process can cause some loss ofvitamin C, so dry fruits may contain lower levels of this vitamin compared tofresh fruits. However, other nutrients, such as certain Bvitamins and minerals like potassium and iron, are still retained in dryfruits. It's worth noting that dry fruits can also contain addedsugars or preservatives in some cases, which may impacttheir overall nutritional profile. When consuming dry fruits, it's advisable tochoose those without added sugars and opt for varieties with no additionaladditives. In conclusion,while dry fruits are still nutritious and offer certain benefits, fresh fruitsgenerally provide a higher water content, more vitamin C, and a lower caloriedensity. Therefore, it's recommended to include a variety of both fresh and dryfruits in your diet to enjoy a wide range of nutrients and health benefits.
