Can a plane sustain in the air?
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. To stay in the air and sustain its flight, an aircraft needs to be moving forward.
Can a plane lose power in the air?
Answer: The total loss of power is extraordinarily rare. The first action would be to relight the engines. If that failed, a ditching would be required, as was the case with 2009’s “Miracle on the Hudson.” After a bird strike disabled both engines minutes after taking off from New York’s LaGuardia Airport, Capt.
Is air travel more efficient than driving?
If you feel bad about driving when you could be flying, there’s good news: Any car that gets more than 44.7 mpg beats the plane. There’s another way to match the efficiency of flying while on the ground: Ride with passengers. Sivak crunched his numbers based on a vehicle load of 1.38 people per car, based on DOT data.
Do planes use more fuel than cars?
Planes burn up more fuel than cars per journey, and therefore produce more carbon dioxide.
Do airplanes use more fuel than cars?
Commercial jets have been more fuel efficient per person per mile than passenger cars for over a decade. In 1970, Sivak reports, it took 10,185 BTUs to move a person a mile in an airplane, compared with 5,067 BTUs to move a person a mile in a car—making flying twice as energy intensive as driving.
Is propeller planes safer than jets?
Both turboprops and jets are powered by turbine engines, so they are essentially the same thing and thus, are considered to be equally as safe. Because of the drag propellers cause, they actually allow the aircraft to stop much more quickly than a jet.
What is the takeoff power of an airplane?
In most GA planes, takeoff power = full power. In larger aircrafts, typically it is slightly below full power to save engine wear. Note that “thrust” is not used to get an airplane off the ground. “Lift” is used to get it airborne and counteract the “weight”.
Why do airliners weigh so much when they are empty?
If the airliner is empty, this can become as much as half of the weight. One reason is altitude capability: Since thrust goes down with the density of air, the static thrust in the cruise altitude is only a quarter of sea level thrust.
What factors affect the speed at which an aircraft can take off?
Minimum flight speed: A low wing loading and low-drag flap settings reduce the speed at which the aircraft can take off. The amount of thrust necessary is the force required to accelerate the aircraft to take off speed, a speed which allows the wings to generate enough lift to sustain the aircraft in the air.
Does airborne really work?
The scientific evidence is lacking that Airborne actually does what it is designed to do. There may be a placebo effect if you take it believing that it will work. Many times a placebo effect can be just as powerful as a pharmaceutical drug, so it’s not a complete write-off. Don’t buy into this quick-fix mentality of Airborne.
