What is the empennage height of the Dassault Falcon 7X?

The empennage height of the Dassault Falcon 7X is a critical measurement that pertains to the vertical dimension of the aircraft's tail section, which includes the horizontal and vertical stabilizers. The correct answer indicates that the empennage height is 26 feet. This measurement is essential for various operational considerations, including hangar space requirements, taxiing under obstacles, and general airspace navigation where certain altitude clearances may apply.

Understanding the empennage height is relevant for pilots and engineers alike, as it affects the aircraft's aerodynamics and stability during flight. The design of the Falcon 7X features an advanced aerodynamic shape that contributes to its efficiency and performance, which can be directly linked to this height.

In comparison, the heights listed in the other options are incorrect as they do not represent the official specifications provided by Dassault for the Falcon 7X. Accurate knowledge of such specifications is vital for safe and efficient aircraft operation.
