Abstract
Longitudinal stability and control links control in speed, altitude and normal acceleration, in particular interest in this chapter, as it relates to the stability seen by the pilot, as opposed to the aerodynamic characteristics of the aircraft. This chapter will discuss static and dynamic stability, and minimum airworthiness codes that define acceptable ranges and responses. Definitions of stability and control terms are discussed, as are the usual tests for determining whether an aircraft’s response is airworthy.
Incidence is the key to the aeroplane’s character as it makes its Hyde and Jekyll transformation from flying tea-tray (concert grand perhaps) to arrow-like rocket; and back again.

And not overload the tailplane at any permitted speed or weight—but that is a structural consideration.

This apparently shows an aeroplane trimmed to a very slow 55 knots—in practice it was flying about 85 knots, but this is GPS data for an aeroplane flying into a strong wind—a useful illustration of the importance of understanding all aircraft instrumentation and what it is really saying.
