The F-14s unique roll control setup, which relies on differential horizontal stabilizers and spoilers rather than traditional ailerons, provided effective control at various speeds but also introduced side forces that could contribute to spin entry. View of the cockpit of NASA’s F-14, tail number 991.

A flat spin happens when the center of gravity shifts too far aft (toward the tail), and the aircraft’s rotation becomes more horizontal. The initial rotation that initiates a spin may result from other factors, such as incorrect control inputs or turbulence. It may seem counterintuitive to reduce your power during a spin.

Sporting tail numbers 28000 and 29000, the VC-25As have been transporting heads of state for the US since 1987. Modifications were made to the aircraft to install a swing tail for easier loading, and the upper fuselage extended for more cargo capacity. The end result was four 747s with three times the cargo volume of a 747-400F.

The trigger can be any external force such as a wind gust or turbulence. To understand the aircraft’s response to a disturbance, you need to understand aerodynamic stability. Placing the center of gravity ahead of the aircraft’s center of lift improves longitudinal stability. How Does a Dutch Roll Begin?

Additionally, only those events where aircraft have been reported as either substantially damaged or written off, or there has been a fatality onboard a public transport flight due to inflight turbulence, have been included. The left winglet of one of the aircraft collided with the right horizontal stabilizer and elevator of the other.
