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 ...
This causes a sense of dizziness or nausea before equilibrium is restored after the head returns to a stabilized state. [4] [5] Crucially, this illusion is based entirely upon perception, and is largely due to conflicting signals between one's sight and one's perception of their body position or motion. [6]
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 ...
The use of head-up displays allows commercial aircraft substantial flexibility in their operations. Systems have been approved which allow reduced-visibility takeoffs, and landings, as well as full manual Category III A landings and roll-outs.
The green Teletubby, Dipsy, was 8 feet (244 cm). The show was filmed on an incredibly large set to create the illusion that the Telletubbies were small. The location of the set was so secret ...
An Aug. 2 Instagram post (archive link) shows a video that begins with several partially undressed men hanging from a beam with their hands tied above their heads in a dark room. A man in a ...
The forward-facing camera used for the PlaneView EVS on a Gulfstream G450. An enhanced flight vision system (EFVS, sometimes EVS) is an airborne system which provides an image of the scene and displays it to the pilot, in order to provide an image in which the scene and objects in it can be better detected.
