How are speed and acceleration described before takeoff and when an airplane takes off?
There are different speeds. They are called v-speeds:
V1
takeoff decision speed
V2
takeoff safety speed
Va
design maneuvering speed
Vb
design speed for maximum gust intensity
Vc
design cruise speed
Vd
design dive speed
Vdf
demonstration dive speed
Vf
design flap speed
Vfe
maximum flap-extended speed (top of white arc)
Vh
maximum speed in level flight with maximum continuous power
Vle
maximum landing-gear extended speed
Vlo
maximum landing-gear operating speed
Vlof
lift-off speed
Vmca
minimum control speed with critical engine out, out of ground effect (red radial line)
Vmcg
minimum control speed with critical engine out during takeoff run
Vmo
maximum operating speed
Mmo
maximum operating Mach number
Vmu
minimum unstick speed
Vne
never-exceed speed
Vno
maximum cruise speed (top of green arc)
Vr
rotation speed
Vref
reference speed for final approach, normally (1.3 x Vso)
Vs
stall speed
Vso
stall speed in landing configuration (bottom of white arc)
Vsse
minimum safe single-engine speed
Vx
best angle-of-climb speed
Vxse
best single-engine angle-of-climb speed
Vy
best rate-of-climb speed
Vyse
best single-engine rate-of-climb speed

Calculate the acceleration of a 2000 kg single-engine airplane just before takeoff when the thrust of its engine is 500 N?
To find the acceleration, we can use Newton's second law: force = mass x acceleration. The force acting on the airplane is the thrust of the engine, which is 500 N. The mass of the airplane is 2000 kg. So, acceleration = force / mass = 500 N / 2000 kg = 0.25 m/s^2.
Calculate the acceleration of a 2000-kg single-engine airplane just before takeoff when the thrust of its engine is 500 n?
To calculate the acceleration of the airplane, we need to first convert the thrust force from Newtons to kilogram-force. Then we can use Newton's second law of motion, F = ma, where F is the force, m is the mass, and a is the acceleration. With the force and mass given, we can rearrange the formula to solve for acceleration: a = F/m. This gives us an acceleration of 0.25 m/s^2 for the airplane.
How far will an airplane travel before takeoff if the plane can accelerate uniformly at a rate of 2.45 meters per second to its takeoff speed of 70 meters per second?
The first step is to find out how long the airplane took before takeoff. If it travels at a uniform 2.45ms-2 acceleration and needs to get to 70ms-1 then this will take 70/2.45 = 28.57142857... seconds. The next step is to calculate the average speed. The plane starts at 0 and ends at 70, so the average speed will be 35ms-1. To find the distance travelled, we multiply the average speed (35) by the time taken (28.57142857...) and this gives 1,000. Thus, the plane travels for 1km before takeoff.
Can you use your computer on an airplane?
Yes, electronics are permitted to be used on aircraft after reaching 10,000 feet after takeoff and before landing.
Calculate the acceleration of a 3000 kg jumbo jet just before takeoff when the thrust for each of its four engines is 30 000N?
40 m/s2
When is the acceleration during takeoff greatest at the beginning of the run along the runaway or just before the aircraft lifts into the air?
Depends on technique, power plant, type of aircraft etc.BUT just at the point of liftoff the forward acceleration is usually at a minimum.
How long do planes typically board for before takeoff?
Planes typically board for about 30-45 minutes before takeoff.
How long does a plane typically board for before takeoff?
A plane typically boards for about 30-45 minutes before takeoff.
Is an airplane taking off down a straight runway an example of accelerated motion?
Yes, as the plane must accelerate from a stop to its takeoff airspeed.
What are the roles and responsibilities of an airplane pilot?
Most pilots work for big airlines 'Airlines require two pilots in the cockpit flying the plane: the captain and the copilot, also known as the first officer. Before a flight, they examine the airplane's control equipment. They check that the weather and flight conditions are good before the fly. The captain has their flight plans checked by the air traffic controllers. The copilot plans the airplane's route the flying time. The pilot has to have get permission before he can takeoff.
How long before takeoff do flights typically begin boarding passengers?
Flights typically begin boarding passengers around 30-45 minutes before takeoff.
Why do turbine engines use fuel to cool the oil in preference to air?
Because there would only be enough airflow to cool the engine while the aircraft was flying. When the airplane was on the ground before or after takeoff there would not be enough airflow to cool the engine properly.
