How high do planes fly? (in Kilometers, Feet, and Miles)

Airplane flying at altitude - how high do planes fly?

How high do planes fly?

Most commercial planes, like the ones you fly on to go visit Grandma, fly at 38,000 to 40,000 feet. They typically fly between 30,000 and 40,000 feet high. It usually only takes about 10 minutes to get there under normal conditions. This is called their cruising altitude which is the height they cruise at for most of the flight. Planes have the ability to fly higher than this but it is the safest height while still being efficient.

Why do planes fly at 38,000 ft?

The biggest reason planes fly at 38,000 feet is the air is thinner. This creates less drag on the plane, so the plane uses less fuel. Fuel is a huge cost for airlines and so fuel efficiency is extremely important.

Above 38,000 feet, the air gets too thin to hold the plane up. The engines also have more difficulty burning fuel as well. And lower than that, there are smaller planes, birds, thunderstorms and increased turbulence to contend with.

38,000 feet is also a safer height to crash land a plane from than 40,000+ feet, if one or both engines fail to a point where an emergency landing is needed.

How high do planes fly in KM?

Commercial planes fly at between 11.5 and 12 kilometers high. If we convert a commercial plane’s cruising altitude of 38,000 feet to KM we get 11.58 KM. There are multiple reasons that flying lower than that or higher isn’t ideal. We’ll go over that a little later.

How high do planes fly in miles?

Typically, commercial aircraft fly around 38,000 and 40,000 feet in the air. This is between 5.6 and 7.6 miles or about 9 to 12.2 miles. Any higher and the air is too thin to hold large commercial planes in the air. Any lower than that and the air is thinner and it becomes less fuel efficient to fly there. 

Thicker air means you need more power and therefore fuel to fly. Think about a car driving uphill vs one that is driving on flat ground. The one driving uphill will use more fuel faster than the one with less resistance driving on the flat ground. 

Can planes fly at 50000 feet?

Large commercial planes don’t fly at 50,000. They can fly up to between 43,000 and 45,000 feet when empty, but don’t typically fly that high with passengers, a full crew and luggage.

Smaller jets can fly at 50,000 feet pretty easily. The Concorde airliner reached a maximum cruising altitude of 60,000 feet. It had special jet engines that allowed it to efficiently cruise at that height.

Why aren’t those still around? Well, an Air France Concorde crashed just after taking off from Paris in 2000. All 109 people on board died. This and other factors caused the plane’s popularity to decline. The maintenance cost was high as well. 

What happens if a plane flies too high?

When a plane flies too high, it encounters air that is not rich enough in oxygen to burn and produce power to fly. The oxygen is less abundant and the plane engines aren’t able to ignite it or burn it as efficiently and air at lower altitudes. The higher a plane climbs, the less combustible oxygen is in the air. At a certain point, planes can’t create enough power to climb higher or fly. 

What is the highest altitude a plane can fly?

The highest altitude a typical commercial plane can fly today is 45,000 feet. Although they typically fly between 38,000 and 40,000 feet high. The highest altitude a commercial airliner flew was the Concorde that had a cruising altitude of 60,000 feet. The highest military airplane to fly was the Lockheed SR-71 Blackbird that flew about 90,000 feet high. 

Can you breathe at 30,000 feet?

Yes, you could. But there is a lot more to this question than it initially sounds. That air could be as cold as 30 degrees below zero Fahrenheit. Then, if you are in a plane and then exit the plane the instant pressure change could be very hard on the body and could cause any number of issues including lungs expanding till they explode. The wind chill would be extreme at 400-500 mph.

If a person were to ride up to that altitude, the lungs would fare a little better but said passenger would meet the same end, with freezing being the end outcome.  They would be fine up to the first several thousand feet, but they wouldn’t make it up to 30,000 feet.

If somehow, a person could protect themselves from the cold and wind, safely attach themselves to the outside of a plane, and ride up to 30,000 feet, theoretically, they could make it up to 30,000 feet and back down again, breathing and safe.

How high do 747 planes fly?

A Boeing 747 has a cruising altitude of 35,105 ft. There are a number of factors that can change a 747’s flying height though. Whether it is full of passengers, crew, fuel and supplies affects the plane’s weight. Other factors are the weather conditions and where the plane is headed for that particular flight. Each plane has an ideal cruising altitude and each flight does as well.

That sweet spot is the place where any plane, including a 747 can burn the least amount of fuel and travel to the destination as quickly as possible.

Do airplanes have keys?

Do airplanes have keys?

Airport - Do airplanes have keys?

Do planes have ignition keys like cars? How do you keep an airplane secure? Does they have keys for the outer doors or cockpit? The short answer is: some airplanes have keys and some airplanes don’t.

Most large planes and jets do not have keys. They start using a combination of switches and knobs. Most small planes do use keys to start, along with keys to interior doors and luggage compartments. Most airplane keys are not required to run the plane. They’re only needed for ignition.

Are keys required to start plane engines?

Typically, large planes and jets do not need keys to start. Many will have keys to secure doors and luggage compartments, though. But, small planes and private aircraft have keys like those you would use for a car. They ignite the engine, but are not often needed to keep the plane running.

If an aircraft requires a key, it will typically have only one engine. These are much easier to operate than dual engine planes. With two engines, as you might expect, both have to be running properly. This takes a lot of work and preparation. You have to know what you’re doing while in the air, too, since you’re managing twice the equipment.

But with a single engine, you won’t need to worry about navigating other buttons and switches in a particular sequence to get the engine running properly. Instead, just turn the key and you’re good to go.

Do commercial airplanes have keys?

Typically, commercial airplanes don’t have ignition keys or keys for doors. Most commercial aircraft have a Cockpit Door Surveillance System, or CDSS. This means that the flight team in the cockpit can see who wants to enter the cockpit door. Most of the time, cockpit doors feature panels where you type in a password to enter. This password is not shared with airline passengers. Only airline staff members know the code.

Most commercial airplanes do not have keys to their exterior doors. The TSA conducts airport security that is thorough enough that doors with locks are not needed. Every passenger has to go through airport security before boarding a commercial plane.

Large jets often have jet bridges instead of doors, which are not locked and unlocked by keys.

You might find some large aircraft with battery master switches. These switches cut off battery power to an airplane in the case of theft. They also prevent your battery from draining which may cause some parts of the plane to fail.

Do small planes have keys?

Most small planes have both ignition keys and keys to interior doors and compartments. Some small aircraft feature throttle locks, which, as the name suggests, lock the throttle. Throttle locks are metal pieces that fit over the throttle and prevent airliners from operating the aircraft. Typically, you can unlock the throttle with either a code or a key.

One reason small aircraft have keys is they are more prone to theft. With a key-powered airplane, as long as the key’s not in the plane itself, it can’t be started. Small planes often sit in large parking lots for up to weeks at a time. They can’t be supervised 24/7 so keys are a great way to keep them secure.

When flying overnight trips, they’re also left in the hangar until the next morning, or the next flight.

Most private jets don’t have ignition keys. Instead, they are used to lock internal compartments and doors. To start a jet, you first need to hook it up to a ground power unit that supplies it with electricity while on the ground. Once that’s hooked up, you can start the engine. Typically, jets will have ignition switches or buttons.

Do large airplanes have keys?

Large airplanes and jets do not have ignition keys or locks. Instead, they use switches and knobs to start the plane. They are flipped and turned in a specific sequence to turn on the engines properly. Generally, large airplanes are more difficult to start than small airplanes, which often have ignition keys.

Some large aircraft have keys for exterior compartments and doors, but the largest jets use jet bridges instead of doors.

You might be thinking: why don’t all large planes have ignition keys? Is it not a security risk? Someone may be able to steal the plane if it’s not locked securely. But, it’s incredibly difficult to steal a plane. The planes are guarded by heavy security and many of them are inside locked garages, hangars, or warehouses. There’re also cameras everywhere, so if you did bypass the security, it wouldn’t be hard for the staff to identify you after the fact.

Do gulf stream airplanes have keys?

Gulf stream jets do not have ignition keys, but some have keys to lock the exterior doors for extra security.

Does the Boeing 747 have keys?

No, the Boeing 747 does not have keys. It starts using a series of switches. The Boeing 747 has what’s called an auxiliary power unit, or APU. Think of it like a generator that powers the plane. To start the Boeing 747, you need to first turn on the APU.

Check out the full process to start the Boeing 747 below.

Do jets have keys?

Most jets do not have ignition keys, but some feature keys to exterior compartments and doors for additional security. Most jets are stored in hangars and constantly monitored, though, so keys are not a necessity.

Do helicopters have keys?

It entirely depends on the type of helicopter. Some helicopters have both ignition keys and keys for the doors. Since helicopters only have a couple of doors, it’s common that if it does have a key, that key will start the helicopter and lock the door. Helicopters that have pistons often have ignition keys, but turbine-powered helicopters do not.

Do fighter jets or military planes have keys?

Fighter jets and military planes do not have keys. Instead, they run by flipping a series of switches to turn on the batteries and start the engines.

Are airports privately owned?

Are airports privately owned? Airport in the evening

Most airports are owned by the federal or local government. Some airports, like the JFK airport, are owned by New York City but operated by the Port Authority of New York and New Jersey. The only private airport in the U.S. is the Branson Airport in Missouri.

A publicly-owned airport is an airport that the government, not an individual or a private company, owns. Comparing publicly owned airports to roads and public schools: both are federally funded, but the main difference is that people don’t pay for airports through tax dollars.

According to the IRS, “airport tax” is used to pay for maintenance of the aircraft. Since the money doesn’t end up in the treasury, it’s not considered a tax, but instead a fee. Airports sustain themselves with these passenger fees and do not receive additional assistance from the federal government.

Are international airports privately owned?

The government owns some international airports and some are privately owned. It is more common to see private international airports than private American airports. In India, for example, there are 17 private airports. The UK has 13 private airports. Whereas, in the USA, there is only one, the Branson Airport.

Are airports privately owned in Canada?

Most airports are not privately owned in Canada. Canada is home to over 500 airports, which are largely owned by the government.

Are airports privately owned in India?

There are 17 private airports in India. The rest are owned by the government.

Are airports privately owned in the UK?

There are 13 private airports in the UK. The rest are owned by the government.

Are airports privately owned in Australia?

Australia has a mix of publicly owned and privately owned airports. Since the federal government passed the Airports Act in 1996, many of Australia’s major airports have been privatized. 

What are the two types of airports?

The two main types of airports are public airports and private airports. Public airports are ones that are owned by the federal or local government. Private airports are owned by an individual, a private company, or a majority of private shareholders. Almost all airports in the US are owned by the government. Private airports are much more common internationally.

Two other common types of airports are domestic and international. These airports only schedule flights within the same country. To fly outside your country, you’ll have to go to an international airport. These airports have customs facilities so they can approve people for flying abroad.

How many major airports are privately owned?

No major airports are privately owned in America. The only privately owned airport in the US is Branson Airport in Missouri. It is not among the busiest airports in the world, nor is it very popular. Internationally, several dozen major airports are privately owned.

Is JFK airport privately owned?

No, the JFK airport is a publicly owned airport. It is owned by New York City and operated by the Port Authority of New York and New Jersey.

Who owns Branson airport?

Branson Airport is owned by Taney County in Missouri. It is the only private airport in the United States.

Are airports federally funded?

Most airports are federally funded, meaning the government pays for them. Only the Branson Airport is privately owned in America, but many airports are privately owned internationally.

Do airlines pay to use airports?

Airlines do pay to use airports. They primarily pay through landing fees, rent for check-in areas, overnight parking fees, and maintenance facilities. Depending on the size of the airport and the type of facilities they need, the airline may pay for more or fewer amenities. Airlines pay the federal government directly who pays for the rest of the airports’ expenses.

How do airports make money?

Airports make money from both airlines and passengers. Most of the revenue from airports comes from airlines. Airlines pay airports to rent out terminals and hangars for their airplanes and they also pay landing fees to land their airplanes at the airport. Passengers pay for parking fees, rental cars, and concessions like food and gifts or souvenirs.

Can you bring creatine on a plane?

Can you bring creatine on a plane?


You can bring creatine on a plane, according to the TSA. They allow you to bring creatine in your carry-on bag or in checked luggage. Powder containers greater than 12 ounces or 350 mL need to be x-ray screened separately before you board the plane. You can carry them on board, but it’s easier to pack them away in your checked luggage.

If you want to take creatine on a plane, keep in mind that the TSA agent may ask you to open the container.

Does creatine go off once opened?

Creatine will not explode when opened. It will last a few days before it loses its effectiveness and doesn’t give you as much energy for a workout. In a sealed container, creatine lasts many years. You don’t need to worry about it expiring. 

Can you store creatine in the fridge?

You can store creatine in the fridge for three to six weeks before it loses its effectiveness. Store creatine in a dry place slightly cooler than room temperature for best results. Before you open creatine, keep it out of the fridge and it will last several years. Once creatine is opened, you can put it in the fridge to make it last longer.

What should you take creatine with?

Workout - Can you bring creatine on a plane?

You can take creatine with water or sugary drinks. Sugary drinks and creatine help absorb the powder more efficiently, but water works fine as well.

Add about 5g of creatine to your drink. Some people can handle higher doses of up to 10g, but you don’t want to eat more than your body can absorb.

Can I take my supplements on a plane?

You can bring supplements on a plane, according to the TSA. They may ask you to open the container, so have it accessible before you enter airport security. You can also pack supplements in your checked baggage. If you’re bringing a large quantity, this is the most convenient.

Can you bring protein powder on a plane?

You can bring protein powder on a plane. If it is over 12 ounces or 350 mL, the TSA will have to x-ray screen the container separately. If you aren’t going to use the powder on the plane, pack it in your checked luggage. This will save you and the TSA agents time.

Can I take protein powder in my suitcase?

You can take protein powder in your suitcase. This is the most efficient way to get through airport security. Most likely, the TSA agents won’t ask you to remove the powder from your checked bag and open it. But, they reserve the right to do so.

How do you pack protein powder for air travel?

What You’ll Need

  • Plastic bags (or a large freezer bag)
  • Measuring cup/scoop
  • Protein powder
  • Shaker bottle

It’s important to keep your protein powder securely packed while traveling. Cleaning up the protein powder can be a huge mess. You don’t want to have to deal with that! Here’s three easy steps to pack your protein powder while on the go.

Scoop protein powder into individual plastic bags.

Each plastic bag should hold about one day’s worth of protein powder. This will make it easy for you to keep track of how much powder you’re using while traveling. If you use a lot of protein powder, you can pack 2-3 servings in each bag. Just make a mental note of how much powder is in each bag before you leave on your trip.

Remove air from the plastic bags and seal them.

Remove the air in the plastic bags so that you will have more space to store them in your shaker bottle. Also, make sure that none of the bags have holes. Secure the Ziploc seal to keep the powder from spilling.

Set them inside your shaker bottle and secure the lid.

If you’re packing light, take all your Ziploc bags and set them inside your shaker bottle. You’ll have your protein powder neatly portioned out and your shaker bottle all in one place.

If all your protein powder doesn’t fit in the shaker bottle, then pack the individual plastic bags in a larger plastic bag. You can bring several large plastic bags, too. But if you want to carry the powder on a plane, keep in mind that anything over 12 ounces needs to be x-ray screened at a security checkpoint.

Let’s say you wanted to use fewer bags to pack your protein powder. Just put all the powder into a large freezer bag and then bring a scoop or measuring cup with you. Then once you get to your destination you can measure out the protein powder.

To be safe, double bag the powder. This way, if one bag breaks, the powder is less likely to spill everywhere inside your checked baggage.

Thanks for reading our article about bringing creatine, protein powder, and supplements on a plane. Remember, they’re both allowed on board, but if you want to save some time at security, pack them in your carry-on bags.
