The speed or velocity of an airplane can vary depending on several factors, including the type of aircraft, its design, and the phase of flight.
During takeoff and landing, airplanes typically operate at lower speeds compared to cruising speeds. Commercial jetliners typically take off and land at speeds ranging from about 130 to 180 knots (150 to 210 mph or 240 to 340 km/h). These speeds can vary depending on the specific aircraft type and the prevailing conditions.
During the cruise phase, where airplanes spend the majority of their flight time, commercial jetliners typically fly at speeds ranging from around 450 to 570 knots (518 to 655 mph or 833 to 1055 km/h). Again, these speeds can vary depending on factors such as the aircraft type, altitude, and atmospheric conditions.
It's important to note that different types of airplanes, such as military aircraft or smaller general aviation planes, can have different speed ranges. For example, military fighter jets can reach much higher speeds, often exceeding the speed of sound, while smaller general aviation planes generally have lower cruising speeds.
In summary, the speed or velocity of an airplane can vary depending on the specific aircraft, the phase of flight, and other factors. Commercial jetliners typically have takeoff and landing speeds around 130 to 180 knots, and cruising speeds around 450 to 570 knots.
