टेक ऑफ या लैंडिंग? जानें किस समय सबसे ज्यादा खतरनाक होती है प्लेन की रफ्तार – aerpplanes speed limit how fast airplanes fly during take off landing kitni speed pe udte hain tvisp
Air travel is the fastest mode of transport which takes us from one country to another within a few hours. But have you ever wondered while sitting near the window during air travel, what will be the speed of the plane now or at what speed is it running on the runway. In fact, the speed seems fast to the person sitting inside, but the science behind the speed of take-off and landing is quite interesting.
How fast do airplanes go?
Every flight is different and its speed depends on many factors. Such as the size of the aircraft, its weight (including passengers and luggage), weather, temperature, altitude and more. Therefore it can be explained as a range of speeds rather than a fixed number.
This math applies
Before taking off, the aircraft moves from the gate to the runway at a speed of about 30-35 km/hour. Initially the aircraft moves slowly so that in case of any emergency it can be stopped immediately or turned safely. When the plane finally takes off, the speed of commercial planes is between 220 to 285 km/h and that of small planes is between 90 to 100 km/h.
If you are wondering why a plane needs so much speed to fly, then the reason is that this speed creates air flow over the wings which pushes the plane upward.
Cruising and landing speed
Once you are comfortably in the air the plane reaches its fastest speed. This is called cruising. At this time the speed of the aircraft is 830-900 km/hour. That means it covers a distance of about 14 km every minute. If your car could go that fast, you would have covered the distance from Delhi to Varanasi (820 km) in just one hour.
The type of aircraft also plays an important role
Talking about landing, the speed of the plane reduces before stopping but not as much as you might think. A commercial aircraft lands at a speed of 240-290 km/hour. Small planes fly at a speed of about 80-90 km/hour during landing.
You would think that this would be much less than at take off but since the plane is already in the air it needs speed to remain stable. In fact, if the speed becomes too low then it can prove dangerous because the pilots will not be able to land safely and softly.
Overall the planes start moving slower. Take off with speed and then travel in the air with your full capacity. Also, before stopping, they descend to the ground at a slow speed.
