Why does taking off in a plane feel weird?

The Curious Case of the Sinking Feeling: Why Takeoff Feels So Weird

The roar of the engines, the rumble beneath your feet, and then… that unsettling sensation of sinking. For many passengers, the initial moments of takeoff aren’t the thrilling upward surge expected, but a disconcerting feeling of descending, a momentary disconnect between what your inner ear tells you and what your eyes see. This isn’t a malfunctioning aircraft; it’s a fascinating interplay of perspective and physics.

The culprit? The changing angle of the aircraft as it climbs into the wind. While the plane is steadily gaining altitude, the initial ascent isn’t a purely vertical trajectory. Instead, it involves a carefully controlled rotation, tilting the nose upwards. This rotation is crucial for generating lift and achieving a safe climbing angle.

This subtle but significant change in the plane’s orientation is particularly noticeable from the rear of the aircraft. As the tail lifts, passengers in the back experience a more pronounced shift in perspective. Your inner ear, responsible for your sense of balance and spatial orientation, detects this tilt as a downward movement, even though the plane is, in reality, climbing. This discrepancy between the visual information your eyes process (the ground receding) and the vestibular information your inner ear receives (a sensation of tilting downwards) creates the unsettling feeling of sinking.

Think of it like this: Imagine sitting on a slowly rising elevator that also tilts backwards. You might experience a sensation of being pushed back into your seat, even as you know you’re ascending. The same principle applies, albeit more subtly, during takeoff.

The intensity of this “sinking” feeling can vary depending on several factors. Larger planes, with longer fuselages, often accentuate this effect, as the rear section experiences a more significant change in angle. Weather conditions, particularly strong headwinds, can also influence the plane’s ascent angle, impacting the sensation. Finally, individual sensitivity to changes in balance and spatial orientation plays a role. Some passengers are simply more susceptible to this disorienting feeling than others.

In conclusion, the weird sinking sensation during takeoff isn’t a sign of impending doom; it’s a perfectly normal consequence of the plane’s ascent angle and the way our perception processes this change in orientation. It’s a testament to the complex interplay between physics, our senses, and our perception of movement. So next time you feel that peculiar drop during takeoff, remember it’s merely an illusion, and you’re actually soaring safely into the sky.
