Question

What illusion might you experienceWhen flying in IMC if the aircraft is in a turn and you turn your head at the same time?

a) Somatogravic illusion (sensation of pitching)
b) Coriolis illusion (feeling of tumbling)
c) Flicker vertigo (disorientation due to light flickering)
d) Elevator illusion (sensation of a rapid climb or descent)

Answer 1

The Coriolis illusion is the illusion that you might experience when flying in IMC and turning your head at the same time. It causes a feeling of tumbling or disorientation due to a mismatch between your vestibular and visual systems.

Step-by-step explanation:

The illusion you might experience when flying in IMC (Instrument Meteorological Conditions) while the aircraft is in a turn and you turn your head at the same time is the Coriolis illusion. This illusion is a feeling of tumbling or disorientation that occurs due to the combination of your head movement and the aircraft's rotation. When you turn your head while the aircraft is turning, it can create a mismatch between the information received by your vestibular system (inner ear) and your visual system, leading to a sense of confusion.
