Why do planes stay still in mid air?


Why do planes stay still in mid air? Airplanes stay in the air because of one simple fact-- there is no net force on them. And with no net force, an object at rest stays at rest and an object in motion stays that way, even if it's in midair 10 kilometers above the Earth's surface. Now, of course, it's not like there aren't forces acting on the airplane.


Do airplanes dump fuel in the ocean?

Fuel dumps are instructed under FAA guidance to be done over remote or oceanic areas, or at an altitude at which the dumped fuel can atomize before reaching the ground, although such guidance may be bypassed in dire emergencies, according to the FAA.


Why do planes dump fuel mid air?

Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight.


Why do planes fly so low sometimes?

Why do the aircraft fly so low? Aircraft have to fly low in order to properly line up with the runways and execute safe landings. Aircraft may, however, appear to be lower than they actually are because their large sizes make them look closer.


Can planes just hover in one spot?

Can an airplane stay up in the air without moving forward just like helicopter? A: Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare.


How long can an airplane stay in the air?

Longest non-stop flights Theoretically, it could fly longer because all commercial planes land with a regulated diversion and reserve fuel and never with zero fuel. As such, the answer is that it could stay more than 20 hours in the air before running out of fuel.


How long can a plane stay in the air without engines?

Flying at a typical altitude of 36,000 feet (about seven miles), an aircraft that loses both engines will be able to travel for another 70 miles before reaching the ground.


Can weather bring down a plane?

Contrary to what many passengers believe, commercial airplanes can fly in almost all weather conditions and are rarely affected by lousy weather.


What causes a ghost plane?

A ghost flight is when an airline operates a plane on a regularly scheduled route with little to no passengers - under 10% of capacity - onboard. This is most often done to make certain airlines can fulfill their contractual obligations so as not to lose one of their most precious assets - airport slots.


What happens if a plane stalls mid air?

The stall is a breakdown of the smooth airflow over the wing into a turbulent one, resulting in a decrease in lift. The lift will no longer fully support the aeroplane's weight, and the aeroplane sinks.


How many hours can a plane fly without landing?

The typical maximum range of an ultra-long-range aircraft is 13 hours; with a second set of crew, you can enjoy an extra three hours without stopping for fuel.


Why don t planes fly at night?

A lot of airports have restrictions on night flights because of noise issues. Also some smaller domestic airports close at night. There are a few that leave late at night in order to take advantage of the time difference in the arrival city. There aren't more because there isn't much demand for them.


Can a plane be too heavy to land?

The maximum landing weight (MLW) is the maximum aircraft gross weight due to design or operational limitations at which an aircraft is permitted to land. The MLW is set in order to ensure safe landings; if an aircraft weighs too heavy during touchdown, it may suffer structural damage or even break apart upon landing.
