How do planes fly?
If you’ve ever watched a jet plane taking off or coming in to land, the first thing you’ll have noticed is the noise of the engines. Jet engines, which are long metal tubes burning a continuous rush of fuel and air, are far noisier (and far more powerful) than traditional propeller engines. You might think engines are the key to making a plane fly, but you’d be wrong. Things can fly quite happily without engines, as gliders (planes with no engines), paper planes, and indeed gliding birds readily show us.
Photo: Four forces act on a plane in flight. When the plane flies horizontally at a steady speed, lift from the wings exactly balances the plane’s weight and the thrust exactly balances the drag. However, during takeoff, or when the plane is attempting to climb in the sky (as shown here), the thrust from the engines pushing the plane forward exceeds the drag (air resistance) pulling it back. This creates a lift force, greater than the plane’s weight, which powers the plane higher into the sky. Photo by Nathanael Callon courtesy of US Air Force.
If you’re trying to understand how planes fly, you need to be clear about the difference between the engines and the wings and the different jobs they do. A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky. So it’s the engines that move a plane forward, while the wings move it upward.
Photo: Newton’s third law of motion—action and reaction—explains how the engines and wings work together to make a plane move through the sky. The force of the hot exhaust gas shooting backward from the jet engine pushes the plane forward. That creates a moving current of air over the wings. The wings force the air downward and that pushes the plane upward. Photo by Samuel Rogers (with added annotations by explainthatstuff.com) courtesy of US Air Force. Read more about how engines work in our detailed article on jet engines.
Is Higher Better?
If airplanes produce more thrust at lower altitudes and can fly faster, then wouldn’t you just want to fly as low as possible to fly as fast as possible? Well, no. And for a few reasons.
First off, there is a speed limit below 10,000 feet above sea level of 250 knots. This is for noise abatement and air traffic control’s spacing of aircraft. So, jets have their airspeed really pulled back until climbing through 10,000 feet to abide by this rule.
Secondly, most weather phenomena happen below 30,000-40,000 feet (except for some of the super cell thunderstorms that can tower up to 60,000 feet or more), and so traveling high keeps you out of this for the most part. Turbulence can happen at any altitude but it is generally more prevalent closer to the ground because of convection (rising heat) from the surface and some obstruction turbulence where the wind more or less bounces off of hills, buildings, and the like. Staying high helps you avoid this as well.
Lastly, flying higher leads to better fuel efficiency. Engines burn a combination of fuel and air, and that ratio is determined by the weight of the air and the weight of the fuel. When you fly higher, the air is less dense and therefore weighs less, meaning that you have to mix less fuel with it in order for it to combust. Said another way, you use less fuel.
Why you should never use airport USB charging stationsAnswered By: Landon Stewart Date: created: Nov 19 2020
Travelers are advised to avoid using public USB power charging stations in airports, hotels, and other locations because they may contain dangerous malware, the Los Angeles District Attorney said in a security alert published last week.Asked By: Jeffery Wood Date: created: Mar 29 2021

Do planes have Wi-Fi?
WiFi in airplanes let you use your gadgets with an internet connection just like on ground, but with the flight mode turned on. … There are two systems of connectivity for inflight WiFi – Air-to-ground and satellite. Air-to-ground system is a ground based system that works similar to mobile data network on cell phones.
Where should I pack my chargers when flying?
—Keep chargers in your carry-on luggage, not in checked bags. —You might want to carry extra battery packs, and not the kind you put in your phone. External batteries, or juice packs, act as miniature power chargers when you can’t find a place to plug in.
Can you charge your phone on Frontier Airlines?
Frontier does not provide inflight Wi-Fi, video streaming capabilities, or any type of onboard entertainment at this time. Refreshment service is limited to paid beverages and snacks only. Frontier does not have electrical outlets onboard for passenger/commercial product use.
How many watts are plane outlets?
Most power systems on airplanes are limited to 75 watts of power per seat, which means a new 17” laptop might not get enough juice to stay charged. Some laptops just use the power to operate, and not to charge.
Why is plane WiFi so bad?
You’ll get less delay because the towers are closer to your plane than a satellite. The downside? No towers, no signals. That means when you’re flying over large bodies of water, above mountains, or passing over countries with cell towers that restrict WiFi access, you probably won’t get any WiFi.
Why can't you use WiFi on a plane?
Since 1991, the FCC has banned the use of cell phones on airplanes because of potential interference with ground networks. … The picocell acts like a mini cell tower that enables phones on the plane and towers on the ground to interact normally.
