Can flights stop in air?

Yes, an aircraft can stay in the air without going forward if the oncoming wind, called headwinds are equal or greater than th minimum speed of that aircraft. This principle is used in the wind tunnels to experiment the flight characteristics by blowing the wind to the aerofoil and assess the aerodynamic changes.

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.

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.

Before each flight, in addition to the checks the engineers complete, one of the pilots will always conduct an exterior walk-around of the aircraft to ensure that they are happy with its condition.

Hydraulic pumps are both engine-driven and electrically driven for redundancy. Some airplanes have a ram air turbine that is lowered when electrical power is lost to provide a backup to power a hydraulic pump and limited electrical generator. As for the loss of the engines, all airplanes can glide to a landing.

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.

Although modern airplanes fly higher but slower than their predecessors, this evolution has been a necessary adaptation to the changing landscape of the aviation industry.

Airplanes rely on a braking system to safely land on runways. At cruising altitude, most commercial airplanes fly at a speed of roughly 500 to 600 mph. When landing, however, they must reduce their speed.

Technically this is the so-called 'stall speed', where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.

In the United States, there are 0.07 fatalities per billion passenger miles, which translates like this: If you fly 500 miles every day for a year, you have a fatality risk of one in 85,000. In short, flying is, by far, the safest mode of transit.
