1. Small sized General Aviation aircrafts :- Their takeoff speed is about 100–140 km/h. 2. Turboprop powered passenger aircraft (small):- They takeoff at about 200–210 km/h.

A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph).
What is the slowest speed a 737 can fly? It depends on many variables; weight, weather conditions, what specific type of 737 etc but it would generally be anywhere from 120-150 knots. It is a function of the weight of the aircraft and its configuration such as flaps, slats and landing gear.
In general, commercial airlines are designed to handle crosswinds up to 30-40 knots (approximately 35-46 mph), and some planes are capable of landing in even higher winds.
With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing. As far as how this happens, it depends on where you are in flight.
Technically this is the so-called 'stall speed', where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.
As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep flying. Power from the engines will translate into speed, if not height.
What does Mach 1 mean? A Mach number is the ratio of an object's speed in a given medium to the speed of sound in that medium. Mach 1, then, is the speed of sound, around 761 mph at sea level on a standard day. The term is also used as a metaphor for high speeds more generally.
According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air. To put that in perspective, the peak of Mount Everest measures 29,029 feet.
Answer: You are correct that a twin-engine jet will have an average takeoff run of 30 – 35 seconds, good observation. It will vary depending on the altitude of the airport, the weight of the airplane and the outside temperature. The lift-off speed (VR) will also vary depending on the weight.
In jet aircraft, an overspeed results when the axial compressor exceeds its maximal operating rotational speed. This often leads to the mechanical failure of turbine blades, flameout and total destruction of the engine.
Rain is just water, no matter the pressure. Modern aircraft can generate lift regardless of the heaviness of the rain. Planes can and will take off and land in the rain. The only real problem with heavy rainfall is the decrease in visibility for the pilots.
Turbulence might occur during your flight in rainy weather due to the presence of different air masses mixing together and causing disturbances aloft. Warm and cold air masses interacting with each other can result in turbulent conditions high in the sky, making your flight potentially more uncomfortable.
