137knots as an average
The aeroplane takeoff is controlled by the engine speed and the elevators.
This depends on the type of aeroplane. In the case of a VTOL jet the speed is actually zero.
"V1" is the speed at which the flight crew must either continue with the takeoff or abort the takeoff. It is the last point at which aborting is an option.
a small 2 seat prop like a cub can be 80 knots
It's a measure of speed. (Like miles per hour (mph), or kilometers per hour (kph)). The Cessna 172 has a takeoff speed of about 55 knots (kts). A Boeing 737 has a takeoff speed of about 135-140 knots. On takeoff, aircraft need to reach a certain speed to get into the air.
Generally for a small Cessna 152 the rotation speed is 50 kias. For larger jets I am not sure but it's a start
A small Cub needs approx 80 knots whilst an A380 can lift at 140.
144 KIAS
An aircraft uses a turbofan engine to reach takeoff and cruising speed. Look up TURBOFAN on Google for more info!
cos 25 = groud speed/120 ground speed = 108.76 mi/h
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.
The aircraft gains speed. Its wing is curved on top and flat on bottom, so it gains lift. Then it soars into the sky with its nose pointing up.
