  2. e how loud it is and what the frequency of its sound output was, in normal cruising flight. The distance sound travels is not going to vary much based on whether it is horizontal or vertical distance. The plane cruising overhead at 18,000 feet is just a little over 3 miles away
  3. In both directions, aircraft are at cruise, and they are plainly audible. Terrain is mountainous with valleys at 4000 ft, peaks up to 8500 feet. Often jet traffic is the only noise you hear on those trails. One one hike, I watched a Martin Mars water bomber cruise through the valley almost at eye level
  4. It doesn't even has to be very silent around you. But because of the speed of sound, you will hear the aircraft later. Here is the approximate time, the sound needs to reach you: Speed of sound at MSL: ~340m/s. 35.000 ft in m: ~10660m. 10660 / 340 = ~ 31s. That means you will maybe hear the aircraft but you are not going to spot it where the.
  5. The rough rule is that when the plane is slow and over a city, the phone will work up to 10,000 feet or so. Also, it depends on how fast the plane is moving and its proximity to antennas, Thompson says. At 30,000 feet, it may work momentarily while near a cell site, but it's chancy and the connection won't last
  6. However, the story changes if the plane is below 8,000 feet, Clarke said. Below 8,000 feet, the pressure is controlled to match the pressure outside, hence the reason your ears only hurt the last..
  7. Some oxygen concentrators will work just as well at a little over 8,000 feet, while others can go as high as 10,000, or 13,000 feet, and still deliver the same high oxygen purity. It's not wise to use an oxygen concentrator beyond its maximum operational altitude, for several reasons

Particularly if this is a once in a lifetime experience for you, you'll want to get as much out of it as possible. That's why we take our skydivers to 18,000 feet rather than 14,000! From here, you'll be in freefall for approximately 20 extra seconds, giving you even more time to feel the rush of the skydive You would see most of the blue sky below you and very dark blue at your same altidude with black sky above you (even at high noon). Also if you had a window bigger than the one foot wide windows, or really, you would need to be in the cockpit with.. Below is an altitude oxygen chart that extrapolates oxygen percentages to real altitude, which you can use in conjunction with Hypoxico systems. This chart will help you find oxygen levels at altitudes you are interested in, starting with the oxygen content of the air at sea level. You can consult with a Hypoxico representative if you have. As you can see in the image above, the airport was built in the old docklands port area for London, and there are water filled docks on both sides of the runway. All aircraft using the airport must be of an approved type capable of making an approach at 5.5 degrees or steeper (this compares with 3 degrees at most other airports) The softest sound an average human ear can detect is BY DEFINITION zero decibels. Double that distance, and deduct 6; that would be 94 decibels at 2000 feet, 88 decibels at 4000 feet, 82 decibels at 8000 feet, 76 decibels at 16,000 feet, and 70 decibels from a jet flying overhead at 32,000 feet

Can a regular human hear aircraft flying above 18,000 feet

On commercial aircraft, the cabin altitude must be maintained at 8,000 feet (2,400 m) or less. Pressurization of the cargo hold is also required to prevent damage to pressure-sensitive goods that might leak, expand, burst or be crushed on re-pressurization. The principal physiological problems are listed below Although I can't say we get a lot of aircraft noise, once in a while, due to winds or air traffic, there will be a long line of planes traveling right over my house, perhaps 6000-8000 feet up, descending into Logan. At night you can sometimes see three in a row, with a fourth one turning on its landing lights

Can You Hear An Aircraft At Cruise? - Airliners

If you plan to travel to a higher altitude and sleep there, you can get sick if you don't ascend gradually: Do not go from a low altitude to sleeping at higher than 9,000 feet above sea level in one day. Instead, spend a few days at 8,000-9,000 feet before proceeding to a higher altitude to give your body time to adjust to the low oxygen. It most often occurs at about 8,000 feet, or 2,438 meters, above sea level. Altitude sickness can affect people without COPD, but it may be more severe in people who do have COPD or some other. Instead, at a cruising altitude of 36,000 feet (10,973 meters), most commercial jets simulate the air pressure at an elevation of 8,000 feet (2,438 meters), about the same as Aspen, Colorado. The Boeing 787 Dreamliner , which has super-strong carbon fiber in its airframe, is able to get that down to the equivalent of air pressure at 6,000 feet. The Death Zone. Used to describe high danger altitude on the Mount Everest ascent, the Death Zone begins at about 8,000 meters or 26,246 feet 3. At this elevation, unassisted from compressed air or oxygen, severe altitude sickness sets in, debilitating the human body and eventually resulting in death 1.The low density of air at this altitude makes acclimation impossible Airplane cabins are pressurized to between 6,000 and 8,000 feet, which is a significant altitude change for your body if you've come from sea level, Shlim told HuffPost. And just as the air in your water bottle expands at higher altitudes, the gas in your intestines can expand on a plane, growing to take up about 30 percent more room than usual

airliner - Can an airplane flying above 35,000 feet be

  1. Above 8,000 feet, ascend no faster than your ability to acclimatize-an average of 1,000 feet per 24 hours of sleeping gain (sleep no more than 1,000 feet higher than the night before). 2. Drink plenty of water. 3. Eat plenty of carbohydrate-rich, low-fat foods. 4. Consult your physician about the uses of acetazolamide to prevent mild altitude.
  2. They were reported by CNN as occurring (at least initially) when the plane was at 38,000 feet. Prof A K Dewdney says he has conducted an experiment showing that commercial cell phones do not work above 8000 feet, even over an area highly populated with cell masts etcetera
  3. High altitude: 8,000 to 12,000 feet above sea level. Very high altitude: 12,000 to 18,000 feet. Extremely high altitude: 18,000+ feet. For context, New York City is at an elevation of 33 feet above sea level. Denver (known as the Mile High City) sits at 5,000 feet, and many Rocky Mountain ski slopes are at 11,000 feet or higher. The Grand.
  4. A gas or air bubble at sea level will expand by 1.25 times at 5,000 feet, 1.5 times at 10,000 feet, and 2 times at 18,000 feet. 1. Only mountain climbers need concern themselves with elevations of 18,000 feet or more. The highest paved road in the United States is the one leading to the top of Mount Evans in Colorado, at 14,130 feet
  5. Other than people calling asking if Delta or Southwest operate out of KSNL, I get the question of what's the biggest plane that can land here? quite a bit. 6000 feet is a decently sized runway, and the biggest thing to land since I started here has been a Falcon 900. I've never flown a twin much less a transport jet

(In mountainous areas like the Rockies where terrain can be higher than 10,000 feet, pilots aim for the minimum safe altitude.) The Boeing 777 is certified to fly up to five and a half hours with. When you travel to a place above about 8,000 feet, your body starts telling you there's something seriously wrong with the air up there. The thin air at high altitudes has considerably less oxygen and pressure. This is because the earth's gravity holds the oxygen close to the surface — so much so that half of the oxygen in the. And 8,000 feet, the maximum allowed, is also physiologically acceptable for normal people, he added. The average Joe in good condition could tolerate 8,000 feet without health effects.

As those bits and pieces settle down through 8,000 feet of water, they move, they don't sink straight down, Williams said. They're going to hit currents. Some of them are going to. This might have been fine for shorter 1960s executives and celebrities, but isn't quite up to snuff today. By comparison, Bombardier's Global 7500/8000 aircraft offer a cabin height of 6'2 (1.8.

You can, of course, ascend more gradually than these rates. Many people ascending from sea level choose to spend several nights at 2500 meters (8000 feet) to 3000 meters (10,000 feet) before beginning acclimatization to higher altitude. During acclimatisation, drink a lot of non-alcoholic drinks My environment is connected via a home VDSL service to the internet and uses dyndns so I can access it when I'm away from home. This environment is located in Auckland, New Zealand. This story started while on a journey of over 8000 miles and starting at 38,000 feet above the US, somewhere between San Francisco and New York Aircraft pressurization systems generally maintain the cabin pressure altitude at about 7000-8000 feet or about 11.3 psi. If you have a sinus blockage, it doesn't take much change in pressure to experience inner ear pain. I've never heard of anyone injecting perfumes or chemicals into the cabin air stream

Altitude sickness refers to a combination of symptoms that can result when you take in less oxygen than your body is used to. This happens when you travel to a high elevation (8,000 feet or higher). It's commonly believed that there's less oxygen the higher up you go. In fact, the concentration of oxygen in the air is the same on top of a. It is equivalent to the outside pressure at 6,000 - 8,000 feet (1,800 - 2,400 m) above sea level. In other words, the atmosphere inside the plane during the flight is comparable to the atmosphere at the top of a 6,000 - 8,000-foot mountain. Since the air pressure is lower, the amount of oxygen in the blood decreases and the gases in the. The signature sign that passengers can use to know when the 10,000-foot transition occurs is the chime. The chime is used to signal to the Flight Attendants that the airplane is above 10,000 feet, which is the minimum altitude where they can begin servicing the passengers in the cabin. Click here to hear some variations of the chime. I suggest when you hear a plane and have a sense of what it is and its general direction, expand a full size map of an airport/heliport near you and try to find it. on average at a height of about 8000 feet. and the sound funneled down the side of 4000 foot mountains, I'll bet it is loud. I live in a fairly luxurious condo in Toronto.

Mobiles at Altitud

Altitude sickness, the mildest form being acute mountain sickness (AMS), is the harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. People can respond to high altitude in different ways. Symptoms may include headaches, vomiting, tiredness, confusion, trouble sleeping, and dizziness. Acute mountain sickness can progress to high altitude. Profound hearing loss: If you have profound hearing loss, you can only hear extremely loud conversation or sound-and even then it's difficult to understand without a hearing aid or cochlear implant. You may prefer using sign language to communicate. People with this degree of hearing loss cannot hear sound lower than 95 dB Any time you go above 8,000 feet, you can be at risk for altitude sickness. Types. There are three kinds of altitude sickness: Acute Mountain Sickness (AMS) is the mildest form and it's very common

Can You Open a Plane Door Midflight? If You Can Lift

inside level is only 8,000 feet. On descents, the pressure is adjusted with decreasing alti­ tude; you land without any noticeable change. Air-cushioned Stops As you land, you'll note another famed feature of the DC-6. After wheels touch, you'll hear engine speeds increa_sed, feel the plane slow down The plane's last known location from civilian flight radar was at 6,800 feet. You can hear human breathing in the cockpit up until the moment of impact, Mr. Robin said. 8,000 feet. per. To understand the process, you first have to know why planes are pressurized in the first place. As a plane reaches higher altitudes, oxygen levels get lower, which can cause serious psychological problems. So the FAA requires that the cabin altitude — the artificial altitude created inside the plane — doesn't exceed 8,000 feet The only difference is that you can hear only one side of the conversation. From time to time I try to use my cellphone at altitude. No one can get a signal at any altitude above about 8000 feet. You cannot make a call from an airliner at altitude. When in an airplane if you call your signal will transmit to hundreds of towers thus. Ascend gradually, if possible. Avoid going directly from low elevation to more than 9,000 ft (2,750 m) sleeping elevation in 1 day. Once above 9,000 ft (2,750 m), move sleeping elevation no higher than 1,600 ft (500 m) per day, and plan an extra day for acclimatization every 3,300 ft (1,000 m)

As the flight attendant rolls down the aisle, taking orders and queueing up drinks, you may hear a subtle sigh of dismay when Diet Coke is ordered. Why? It takes forever to fizzle down, pour and serve. Because the airplane cabin is pressurized to 8,000 feet rather than to sea level, it adds more bubbles than normal This way you can breathe normally without needing supplemental oxygen. When cruising above sea level at about 5000-8000 feet the oxygen levels drop significantly (by upto 25%) which is felt. On the other hand, the air in an airplane is not at sea-level pressure. Since there is a maximum pressure difference between inside and outside, at altitude the cabin pressure altitude is typically between 5,000 and 8,000 feet (although it can go up to 10,000 feet). So flying in a plane is like spending a few hours in the Rockies 3. You Can Get Dehydrated. The air you breathe in the plane cabin actually comes from outside, and air at that altitude has very little moisture. This air is very dry, having a humidity of under 10 per cent, says Quay Snyder, MD, MSPH, president and CEO of Aviation Medicine Advisory Service. Dehydration can lead to a feeling of fatigue.

A: Prolonged sitting on an airplane can increase the risk of blood clots forming, especially in the legs. Although space is limited, it helps to do a few stretches. Do be considerate of your fellow passengers. On long flights, some airlines have exercise videos on the personal TV sets. Look for them the next time you fly While you are flying at FL 250, you hear ATC give an altimeter setting of 28.92 Hg in your area. At what pressure altitude are you flying You are enroute at 8000 feet MSL on an IFR flight plan. What is the most appropriate source for obtaining the altimeter setting During preflight, you note that the airplane has a heated windshield. When the airplane is flying (typically above 20,000 feet), the cabin is pressurized to a pressure of about 8,000 feet. This keeps the people on the plane from passing out (the air is way too thin above 20,000 feet)

At 1:29, you start plummeting out of the sky at the dive-bombing fighter-plane rate of 8,000 feet-per-minute. You float up against your seat belt at minus 2Gs as you hear your copilot radio, MAYDAY! MAYDAY! MAYDAY A series of Navy and Air Force programs in the 1950s and 1960s used pressure vessels or pressure suits to get balloonists higher, some to above 100,000 feet. Skydiver Nicholas Piantanida set an unofficial record—123,500 feet—in 1966, but a later attempt went awry when his helmet depressurized At 11:15:59, the controller radioed that there was an aircraft about 20 miles ahead of him that also was going to Parkersburg, and it was at 8,000 feet. The pilot responded, We'll try eight. The controller cleared the pilot to climb to 8,000 feet, and the pilot acknowledged You can watch it here: The 4-minute video shows the drone's ascent all the way up to 3.4 kilometers, or ~2.11 miles, above ground (~11,155 feet). At this altitude, the drone is flying above a.

You know, I can't hear a goddamn thing. Our ears were ringing, too, after a sim­ilarly humiliating defeat in 1988, when we agreed to a race with our sister magazine Flying Conclusion. The Boost Oxygen product is totally helpful for hiking adventures at higher altitudes. The oxygen was particularly effective in relieving the minor symptoms of altitude sickness while hiking. The benefits of inhaling the oxygen were noticeable at 5000 feet in Boulder and even more so above 8000 feet The misalignment caused the operator to believe that the Ukrainian plane, climbing gradually to 8,000 feet (2,440 meters) as it departed from Tehran's Imam Khomeini Airport, was instead a small.

On commercial flights, oxygen masks descend automatically if the plane loses cabin pressurisation over an altitude of 14,000 feet. According to flight tracker Flight Radar 24, Flight ET302 climbed to just over 8,000 feet - not high enough for the oxygen masks to automatically drop down Free shipping on millions of items.

At 2000 feet, calls could be made about half the time. At 4,000 feet only an average of one in 4 calls was completed. At 6,000 feet, the average was 1 in 12 calls connected. At 8,000 feet and above there was no connection by any of the phones Looking at flight tracking, it seems that the plane was only in the air for a total of 25 minutes, and it reached a highest altitude of 8,000 feet. The plane returned to the airport pretty immediately, as you can see based on the below map from Flightradar24 I survived crash-landing a plane. Jerry Garapich. As told to Megan Messerly. Sunday, Aug. 9, 2015 | 2 a.m. It was a beautiful day. The sky was clear, and there was very little wind. Doug Reichardt.

You carry 6 gal of gas (total weight approx 48 lbs). This is now a total of 750 lbs. You will need a MINIMUM of 15 hp to plane. So, you stick a 15 hp engine on it and you are happy. You then invite your friend to fish with you on your new boat. He weighs 200 lbs. You now have 950 lbs, and your boat will not plane, and you are not happy.... DONALD RUMSFELD: You might pause there for a second. What he's talking about is a plane comes up underneath and the jet wash jars the slower, more stable, bigger aircraft and causes turbulence. The pilot would maintain 8,000 feet, then climb to 11,000 at c, or prior to c if necessary to comply with an MCA at c. (14 CFR Section 91.177(b).) Upon reaching d, the pilot would descend to 8,000 feet (even though the MEA was 7,000 feet), as 8,000 was the highest of the altitude situations stated in the rule (14 CFR Section 91.185 Jet take-off (at 305 meters), use of outboard motor, power lawn mower, motorcycle, farm tractor, jackhammer, garbage truck. Boeing 707 or DC-8 aircraft at one nautical mile (6080 ft) before landing (106 dB); jet flyover at 1000 feet (103 dB); Bell J-2A helicopter at 100 ft (100 dB). 100: 8 times as loud as 70 dB For most drop zones in the United States, the average altitude for skydiving is 10,000 feet. That's because most drop zones operate a small, efficient, single-engine aircraft called a Cessna 182 which is powerful enough to take you to 10,000 feet. From 10,000 feet, a tandem jumper can expect to be in freefall for around 40 seconds, followed by.

Tips for Traveling to High Altitude with Portable Oxyge

The Difference Between 14,000 and 18,000 Feet Skydive

If the airport you are taking off from or landing at is at sea level with a 5000-foot runway (for example), light to mid-size jets and turboprops are highly capable. That said, every 2000-feet in elevation compared to sea level will generally result in the need for an additional 1000 feet in runway length An altitude generator can produce varying oxygen levels from sea level (20.9% oxygen) to 20,000 feet to 6000 meters (9.5% oxygen). By breathing rare air, you can pre-acclimatize before you leave home. You can climb, run, ski, or bike at high altitudes without altitude sickness and, because altitude creates new red blood cells, with more speed.

What will happen if a plane flies above 60,000 feet? - Quor

Try a low-impact activity on your first day, such as snowmobiling. Breckenridge offers many alternatives to skiing and snowboarding, so you can still enjoy yourself while you get acclimated to the altitude. If you are flying into Denver, consider flying in a day early and staying in Denver the first night. Denver's elevation is 5000ft 3) Finally, mix in humidity. The last factor (and the one you don't compute) is humidity. Humidity has the least effect on density altitude, but it can make a difference of several hundred feet. Simply put, water vapor weighs less than the nitrogen and oxygen that make up most of the atmosphere. When the humidity is high, the air is less dense Excellent design choices all around. • Better sleep on long flights. Because the 787 is pressurized at about 6,000 feet rather than 8,000 feet, you'll breathe easier. More oxygen in your lungs. You're experiencing 8,000 feet of air pressure, which reduces your perception of sweetness and saltiness. The humidity is also lower, by 5 to 15%, so your olfactory system is not working as it.

Fly the Airplane! A review of recent ASRS reports indicates that failure to Make sure you can hear some transmissions before taking off into IMC. The autopilot cannot be relied on to reduce pilot load when there are with an assigned 250 knot speed in the descent. 8,000 feet was the selected altitude in the window for the VNAV Serious effects of hypoxia typically start at altitudes of around 8,000 to 10,000 feet, Olson said, and the passengers may not have known that they were suffering from a loss of oxygen Altitude sickness is a condition that occurs at higher altitudes, where there is less oxygen in the air. Learn more about the symptoms, causes, and treatments here The 80x100 hangar building kit from General Steel is an ideal option for aircraft owners looking to shelter their most prized possessions. The steel construction of our building kits offer a distinct advantage over traditional building materials due to their clear span framing, which provides 8,000 square feet of column-free, uninterrupted space This causes symptoms such as a headache and not feeling like eating. It happens most often when people who are not used to high altitudes go quickly from lower altitudes to 8,000 feet or higher. For example, you may get a headache when you drive over a high mountain pass, hike to a high altitude, or arrive at a mountain resort

Altitude To Oxygen Chart - Oxygen Levels At High Altitudes

If you stand on the beach, your eyes are probably between 5 and 6 feet above the sandy beach (depending on your height). From there you can see about 2.7 miles across the ocean. Now, let's say you go up on a sand dune next to the beach, taking your eyeballs 50 feet into the air. Then, you can see about 8.37 miles across the ocean 0. Airplane performance can be defined as the capability of an airplane to operate effectively while serving a specific purpose. Among the elements of performance are takeoff and landing distances, rate of climb, ceiling, speed, payload, and fuel economy. Answer these questions and see if you can correctly determine all the factors required for.

Is the Runway Long Enough? Which Planes Can Land There

explosion. No hearing protection (ear muffs or ear plugs) can help you there. These madness sound levels will never be measured but only estimated or calculated. Ultrasound between 20 kHz and 1.5 GHz does not belong to our human hearing. Infrasound below about 16 Hz is not audible for the human ear, but we can feel high sound levels Airplane doors are impossible to open at cruising altitude, which is about 36,000 feet above sea level. Cabins are pressurized to mimic conditions at 8,000 feet above sea level to keep passengers alive. The lower the air pressure, the harder it is for people to breathe. n*gga aint getting those fu*king doors open at all. Who cares about that. How many feet is the plane actually moving up or down, and side to side? The formations were short—about 8,000 feet at the tops, and deceptively pretty to look at. you can often hear the.

Can you see a plane flying at 30000 feet? - AskingLot

Thankfully that's not that much of an issue today, with the sophistication of monitoring systems, so we hear about planes like the Emirates flight a few weeks ago that had a pressurization annuciation and the pilots began a controlled decent to a lower altitude (like 10,000 feet) and continued on safely Where the airplane will touch down, then, depends on where the wheels are in relation to your eyes, the things doing the aiming. The answer varies with aircraft. We'll use the Gulfstream G450 as an example, but you can do the math for you airplane if you wish. Or you can just take away the bottom line message: don't aim for brick one As you climb in altitude, atmospheric pressure decreases, which can affect your body in many different ways. An airplane's typical cruising altitude is somewhere between 36,000 and 40,000 feet If you want a basic hangar without utilities like power and water, on average, you can rent a hangar for between $50 and $300 per month. For someone who only uses his or her plane occasionally as a hobby, this may be a good option to consider. However, this may not be a good option for a corporate plane Here is where they could come to talk, think and write about physics while training like Olympians -- hiking, scaling 14,000-foot peaks, cycling up mountain passes, jogging and playing cut-throat.

What causes descending aircraft to make a noise like a

When Vice President Dick Cheney was treated for a blood clot in 2007 after a series of long airplane flights, it wasn't all that surprising. Cheney was 66 years old and had a long history of heart disease, and abnormal clotting can be characteristic of that diagnosis.Far more surprising is the fact that 47-year-old former Vice President Dan Quayle developed blood clots after a long plane. A plane you can drive. Flying cars are not just the stuff of sci-fi movies anymore. Massachusetts-based Terrafugia Inc. announced this week that its street-legal prototype, the Transition, completed its first flight last month, bringing the company closer to its goal of selling the flying car within the next year This relationship holds up to about 6,000 feet and is a bit less above that. As an example, if your corrected barometer value is 29.54 inHG and you are currently at 5,000 feet, this is how you would uncorrect your barometer value: 29.54 - (1 x 5,000/1,000) = 29.54 - (5) = 24.54 inches H COVID update: GoJump Santa Cruz has updated their hours and services. 377 reviews of GoJump Santa Cruz The staff is great! I can't say enough good things about them. Laura and Andy totally own my skydiving virginity. Lucky for me, it wasn't an awkward post-prom, back seat with a discarded corsage pin stabbing in my right butt cheek sort of affair

Travel to High Altitudes Travelers' Health CD

Treating the pain on the flight is necessary to help you stay comfortable in the air until you can see your dentist to solve the underlying problem. Pressure Changes As airplanes reach cruising altitudes of around 40,000 feet, cabins are pressurized to the equivalent of 6,000 to 8,000 feet above sea level The Earth's radius (r) is 6371 km or 3959 miles, based on numbers from Wikipedia, which gives a circumference (c) of c = 2 * π * r = 40 030 km. We wish to find the height (h) which is the drop in curvature over the distance (d) Using the circumference we find that 1 kilometer has the angle. 360° / 40 030 km = 0.009° You can also think of it this way - if the bad guys could somehow smuggle explosives on board, why bother with such an elaborate and flawed plan as letting snakes loose on the plane? I live in Southern California and I can hear the snakes 50 yards which is about 8,000 feet). A cargo door is left open to allow the snakes into the.
