Can an airplane stand still in the air?

It was a question and answer before 4 years.Now after that 4 years what is the status of the new technology on aircrafts, especially on business/commercial airlines whether they can stand still in air?If not why can not they and how can jumper jets and other special crafts stand still? Why can not it modified like Helicopters as they stand still in air?Pls, experts/aeronautical engineers explain it.

    Airplanes must move continuously through the air in order to remain aloft.

    Helicopters are able to hover in one place because their "wings"—meaning the main rotor blades—continue to move through the air as they hover, thereby providing the lift necessary to keep the helicopter flying. Unfortunately, this is far less efficient than fixed wings on the sides of an airplane, which is why most air travel is by airplane rather than helicopter.

    There has never been an effort to design commercial aircraft to have a hover ability.

    Jump jets accomplish a vertical motion by redirecting the engine thrust by rotating the exhaust nozzle. The Osprey prop plane rotates the entire engine nacelle to accomplish a hover effect. In fact, that plane cannot land in the ordinary way because the blades are too long to clear the ground. It has suffered multiple accidents so far.

    Vertical takeoff or landing requires a lot more fuel than the standard takeoff, and in the way it would be implemented in a commercial jet I think it would be much less stable in many ways than the usual takeoff/landing method. Anything that decreases stability will eventually lead to more accidents.

    Why do you think this would be a good modification?

    The harrier fighter jet can, and maybe other similar craft, but commercial airliners and all conventional planes cannot. There is simply no need for these planes to have this ability.

    Although, if a plane is traveling into the wind and the wind speed is more than the plane's stall speed, the plane could achieve lift and stay airborne while staying still (or even moving backward) relative to the Earth's surface, but that's highly unlikely for almost all aircraft.

    Sir: advertisement airplanes would desire to fly at a speed of roughly one hundred thirty miles in step with hour (the coolest quantity is constrained to the specific plane) to maintain adequate left over the airfoil surfaces of the wing and wing roots to maintain the plane aloft. in case you have considered advertisement plane curiously soaring in mid air, i think that the sight became an phantasm based upon your perspective of viewing the plane. whilst an plane is flying very slowly and coming fantastic at you, or going immediately far off from you, that is not common to hit upon action in a quick look. This lack of ability to etect action is larger by 0 alterations in altitude, and larger distance from the viewing element. the only advertisement plane i'm conscious of that may certainly "hover" in place are specific commuter helicopters that shuttle passengers from one place to a different on short hops. A helicopter can hover in one spot for long classes of time if decide for be by way of shown fact that the carry required is generated by ventilation over the rotor blades not over truthfully plane wings. The wings decide for stream during the air to enhance carry.

    The Harrier, informally referred to as the Jump Jet, is a family of British-designed military jet aircraft capable of V/STOL (vertical/short takeoff and landing) via thrust vectoring.

    ***************************************************************************************************************

    The Harrier family is the only truly successful design of this type from the many that arose in the 1960s.

    ***************************************************************************************************************

    There are four main versions of the Harrier family: Hawker Siddeley Harrier, British Aerospace Sea Harrier, Boeing/BAE Systems AV-8B Harrier II, and BAE Systems/Boeing Harrier II. The Hawker Siddeley Harrier is the first generation version and is also known as the AV-8A Harrier. The Sea Harrier is a naval strike/air defence fighter. The AV-8B and BAE Harrier II are the US and British variants respectively of the second generation Harrier aircraft.

    Technically, no. They are a different type of aircraft. Each has it's purpose and design.

    Because technology is applied science, not magic.
