The head-up illusion involves a sudden forward linear acceleration during level flight where the pilot perceives the illusion that the nose of the aircraft is pitching up. The pilot's response to this illusion would be to push the yoke or the stick forward to pitch the nose of the aircraft down.
The Inversion Illusion results from a steep ascent followed by a sudden return to level flight; the resulting relative increase in forward speed produces an illusion the aircraft is inverted. [8] The Head-Up and Head-Down illusions are similar, involving sudden linear acceleration (Head-Up) or deceleration (Head-Down), leading to a ...

The Coriolis effect is a concern for pilots and astronauts, where it can cause extreme disorientation. [14] [15] [5] [16] [17] This happens as pilots turn or rotate their aircraft, while also turning their head.
In contrast to most HUDs found in aircraft, automotive head-up displays are not parallax-free. The display may not be visible to a driver wearing sunglasses with polarised lenses. Add-on HUD systems also exist, projecting the display onto a glass combiner mounted above or below the windshield, or using the windshield itself as the combiner.

The attitude indicator (AI), also known as the gyro horizon or artificial horizon, is a flight instrument that informs the pilot of the aircraft orientation relative to Earth's horizon, and gives an immediate indication of the smallest orientation change. The miniature aircraft and horizon bar mimic the relationship of the aircraft relative to ...
