The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw. These are collectively known as aircraft attitude , often principally relative to the atmospheric frame in normal flight, but also relative to terrain during takeoff or landing ...
The "power-pitch couple" in light aircraft is usually small, that is, the engine is positioned in line with the centre of gravity, so changes in power do not cause large changes in pitch. UPRT techniques are designed for jet aircraft, particularly with underslung engines where a large increase in thrust can cause the aircraft to pitch up (the ...
The longitudinal stability of an aircraft, also called pitch stability, [2] refers to the aircraft's stability in its plane of symmetry [2] about the lateral axis (the axis along the wingspan). [1] It is an important aspect of the handling qualities of the aircraft, and one of the main factors determining the ease with which the pilot is able ...
The flight path during a barrel roll has the shape of a horizontal corkscrew and follows a helical path. Aileron roll; 360° revolution about the longitudinal axis at maximum roll rate. It consists of a pitch-up followed by a roll which is uncontrolled in the pitch axis, resulting in an initial climb, and then descent to the original altitude.
In aviation, a flight director (FD) is a flight instrument that is overlaid on the attitude indicator that shows the pilot of an aircraft the attitude required to execute the desired flight path. Flight directors are mostly commonly used during approach and landing. They can be used with or without autopilot systems.

A Canadian aeroplane flight instructor (left) and her student, next to a Cessna 172 with which they have just completed a lesson. Flight training is a course of study used when learning to pilot an aircraft. The overall purpose of primary and intermediate flight training is the acquisition and honing of basic airmanship skills.
