Can flight stay still in air?
NO, at least not during landing
. When landing in strong head wind the pilots will use higher air speed. This is because strong winds have a nasty habit of changing in strength or direction quickly and if the head wind reduced suddenly, the plane would loose lift and crash.
Can a plane stay in the air without moving?
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. … To stay in the air and sustain its flight, an aircraft needs to be moving forward.
Can passenger plane stay still in air?
Can an Airplane stand still in mid-air? Technically,
it is possible for an airplane to hover for a few moments
, but only in the rarest of circumstances. If weight and lift cancel each other out at the same exact time that thrust and drag cancel each other out, the plane would hover until one of these variables changed.
How long can a plane stay up in the air?
Planes can now fly for
21 hours non-stop
.
Can helicopters stop in mid-air?
A
helicopter that is flying forward can stop in mid
-air and begin hovering very quickly. We'll cover this signature maneuver next.
Why do airplanes stay still in the air?
Airplanes fly because the air pressure hits against the wind. Airplanes stay in the air by
the air pushing the wings
. Airplanes stay in the sky because the wind goes up and travels through the wing to keep the plane in flight.
What is the longest flight in the world?
The longest flight in the world by distance is
QR921
. Qatar Airlines' Auckland to Doha route comes in at 14,535 km/9,032 mi/7,848 nm.
How long can a plane stay in the air without engines?
A passenger jet could glide for up to
about 60 miles
if it suffers a total engine failure at its cruising altitude. Here's an example. A typical commercial aircraft has a lift to drag ratio of around 10:1. This means that for every 10 miles it travels forward it loses 1 mile in altitude.
What temp do planes stop flying?
With many commercial airplanes boasting a maximum operating temperature of
over 120 degrees Fahrenheit
, you might be wondering how common it is for commercial airlines to ground airplanes because of extreme heat. Well, it's happened in the past, and it will likely happen again in the future.
Why do helicopters take off backwards?
Helicopters take off backward to
allow the pilot to keep the helipad in sight in case they need to re-land in an emergency
. When taking off vertically, the helipad disappears out of sight around 30ft to 50ft up, backing up allows the pilot to keep the helipad in sight through the chin bubble window.
Can helicopters fly upside down?
Flying a helicopter upside down is rather different from flipping over an aerobatic airplane, whose wings can generate lift whichever way they're pointed.
Helicopters can only can only send lift-generating air in one direction
. Turn it over, and it's going to accelerate you toward the ground.
Can helicopters go backwards?
Unlike an airplane,
a helicopter can fly backwards or sideways
. It also can hover in one spot in the air without moving. This makes helicopters ideal for things an airplane cannot do.
Can a plane reverse?
Answer: Many jets have
the capability to redirect much of the exhaust from the engine out the side and slightly forward
. This is known as reverse thrust. The primary use for reverse thrust is to aid in deceleration during landing. … Today, most of the larger jets have engines mounted under the wing.
Can a plane door be opened in the air?
Airplane doors are impossible to open at cruising altitude
, which is about 36,000 feet above sea level. Cabins are pressurized to mimic conditions at 8,000 feet above sea level to keep passengers alive. The lower the air pressure, the harder it is for people to breathe.
Why do planes sometimes look like they are not moving?
One reason is the
aforementioned higher air density near the ground
. The other is due to wing flaps, which are activated during takeoff and landing. When the flap is raised, it increases the coefficient of lift associated with the airplane significantly.
Why do planes not fly over the Pacific?
The main reason flight don't go over the Pacific Ocean is
because curved routes are shorter than straight routes
. Flat maps are confusing as the earth itself isn't flat. As a result the straight routes don't offer the shortest distance.
