Aerodynamic & Operational Physics

High dynamic pressure at cruise speed (q = ½ρV²) multiplies impact force exponentially (force quadruples when velocity doubles).
Windscreen shatter causes high-velocity air blast, debris hazard to pilot eyes, sudden noise, and severe trim change.
Immediately lower head behind glare shield, protect eyes, establish control by attitude/power, trim for safe maneuvering speed (V_A), and don oxygen/glasses if needed.

CASA & FAA Exam Gotcha Alert

Exam Trap: High-speed low-level flight increases bird strike velocity impact exponentially. Slow to V_A before descending through known migratory bird altitudes.

Frequently Asked Questions & Exam Explanations

What airspeed should you maintain after a bird strike?

Fly below V_A (Maneuvering Speed) or structural safe speed to reduce dynamic air pressure on remaining windshield structure.
