A traveler filmed the actual speed of an airplane during takeoff. While passengers often don’t think about the aircraft’s velocity while comfortably seated at 30,000 feet with snacks, the speed can be a concern for some. To dispel any uncertainty, a Reddit user recorded the plane’s speed during ascent, which left other users on the platform astonished.
A Reddit user anonymously measured the speed of the airplane during takeoff, surprising fellow commenters.
Flying magazine details that takeoff speed isn’t uniform and varies based on aircraft type, influenced by factors such as aerodynamic design, size, weight, and airflow conditions. For instance, the Boeing 747-400, a popular passenger jet, generally requires around 160 knots for takeoff, although the video posted by the Reddit user demonstrated a higher speed.
Flying magazine explains that aircraft weight significantly affects takeoff, with heavier planes requiring more lift to become airborne. Aircraft designed for heavy loads typically feature high-lift wings and powerful engines to achieve the necessary takeoff speed and ensure sufficient airflow over the wings. While the specific model of the aircraft in the Reddit user’s video remains unidentified, it appeared to reach speeds approaching supersonic levels, as indicated by a phone app recording a maximum speed of 373 km/h. One commenter humorously noted that takeoff is their favorite part of flying.
They enjoy the thrilling sensation of being pushed back into their seat during takeoff, and also appreciate being able to order drinks mid-flight. However, someone noted that a speed-measuring app might not be accurate, arguing that the speed it showed during takeoff was higher than what’s needed even for the largest planes like the A380.
