AUTOPILOTAn autopilot is a system used to control the trajectory of a vehicle

without constant 'hands-on' control by a human operator being required. Autopilots do not replace a human operator, but assist them in

controlling the vehicle, allowing them to focus on broader aspects of operation, such as monitoring the trajectory, weather and systems.

[1] Autopilots are used in aircraft, boats (known as self-steering gear), spacecraft, missiles, and others. Autopilots have evolved significantly over time, from early autopilots that merely held an attitude to modern

autopilots capable of performing automated landings

Black BoxIn science, computing, and engineering, a black box is a device, system

or object which can be viewed in terms of its inputs and outputs (or transfer characteristics), without any knowledge of its internal

workings. Its implementation is "opaque" (black). Al most anything might be referred to as a black box: a transistor, algorithm, or the human

brain.

The opposite of a black box is a system where the inner components or logic are available for inspection, which is most commonly referred to as

a white box (sometimes also known as a "clear box" or a "glass box").

CobraIn aerobatics, Pugachev's Cobra (or Pugachev Cobra) is a dramatic and demanding maneuver in which an airplane flying at a moderate

speed suddenly raises the nose momentarily to the vertical position and slightly beyond, before dropping it back to normal flight. It uses potent engine thrust to maintain approximately constant altitude through the

entire move.[1] The manoeuvre supposedly has some use in close range combat,[2] and is an impressive trick to demonstrate an

aircraft's pitch control authority, high angle of attack (AOA) stability and engine-versus-inlet compatibility, as well as the pilot's skill.
