What are the forces on a plane when it is still?
When a plane is still on the ground, the main forces acting on it are weight and normal force. Weight is the force due to gravity acting downward, while the normal force is the force exerted by the ground perpendicular to the plane to support its weight. Additionally, there may be frictional forces acting on the wheels to prevent the plane from moving.
How can a double-deck Airbus A380 still get off the ground?
When the first Boeing 747 was introduced, spectators said the plane did not leave the ground - the ground left the plane. This may bethe case with the a380! Larger planes have been built - namely the An225, a Russian transport plane with 6 jet engines.
What rotates when a plane takes off?
Rotation is when the aircraft pivots around the axis of its main landing gear while still on the ground. At rotation, the nose wheel lifts off the ground while the main landing gear wheels are still in contact with the ground.
Can you take effigen on a plane?
It is still illegal even if you are not on any countries soil, when you take off from the ground it is understood that you are already in the country where the plane will land and therefore that countries laws are in effect.
How trigonometry used in geography?
Principally in surveying by triangulation: you divide the countryside into imaginary adjacent triangles, each lying on a plane in three-dimensions (E-W, N-S and altitude) between defined points on the ground, so a lot of advanced trigonometry is necessary to calculate the co-ordinates of the triangles' apices. Nowadays large-areas maps are generated from satellite images but triangulation is still necessary for small-scale work such as in building and civil-engineering detail mapping and setting-out.
Flight can stay in the air without moving?
Yes, it is possible for an airplane to stand still, or even go backwards, while flying. The easiest method to do so is to fly in winds higher then what the plane needs to stay aloft in. For example, a plane with a stall speed of 70 mph could climb to an altitude that has a 70 mph wind and have 0 mph ground speed. Personally, I would not wish to be that pilot as turning the plane or basic manuvering could be problematic. The ride would hardly be smooth.
During a takeoff in still air an airplane moves at a speed of 120 mih at an angle of 25 above the ground What is the ground speed of the plane?
cos 25 = groud speed/120 ground speed = 108.76 mi/h
A jet plane has a speed through still air of 425 mph but suddenly flies into against a head wind of 50mph How long will this plane need to cover 250 miles over the ground?
40 minutes
What is the fastest top speed reached by a plane?
The Lockheed SR-71A Blackbird, after fifty years, is still the highest performing manned aircraft, that can take-off from a ground based facility, unequaled in speed, range, and altitude, and astonishing good looks. The ultimate record was set in 1976 @ 2,193.167 mph in horizontal flight from New York to London at 85,000 feet
What do you call coal still in the ground?
Coal still in the ground is called "coal reserves".
Can you open the door of airplane in emergency?
If you are equipped with a parachute, you can open the door of a plane in midair and jump out, but if you don't have a parachute there is not much you can accomplish by opening the door while the plane is still in the air. Once the plane is on the ground, you are of course free to open the door and leave. what are you a terrorist why are you trying to open the door on an air plane what are you going to do plant the bomb and jump out?
Disadvantages of domestic flights?
While traveling by plane is usually faster it still has a few disadvantages. The main disadvantages are some people are scared of flying, delayed flights, altitude changing causing pressure, and the occasional luggage loss.
