Scenario & Physics Summary
Rapid forward acceleration on takeoff stimulates otolith organ otoliths, creating false sensation of steep pitch-up, prompting pilot to push nose DOWN into ground.

Aerodynamic & Operational Physics
Otolith organs in inner ear sense linear acceleration and gravity vectors.
Forward acceleration creates a resultant inertial vector tilted backward.
Brain misinterprets backward vector as aircraft nose pitching UP.
Without visual horizon, pilot instinctively pushes stick forward, diving into terrain at high speed.
CASA & FAA Exam Gotcha Alert
CASA / FAA Exam Trap: Somatogravic illusion occurs during RAPID ACCELERATION (takeoff, go-around) in low visibility. Trust instruments, do NOT push nose down.
Frequently Asked Questions & Exam Explanations
What causes the somatogravic illusion during night takeoff?
Rapid forward acceleration tilts the inner ear gravity vector backward, tricking the brain into feeling a steep nose-high pitch attitude.
