Normal acceleration feedback, a term often used in the field of aviation, refers to the sensory input provided to pilots when their aircraft experiences changes in its rate of ascent or descent. There are several synonyms that can be used to describe this feedback, which include pitch feedback, vertical acceleration feedback, and vertical speed indication. These terms all refer to the same concept of providing a pilot with information regarding the aircraft's rate of climb or descent. Additionally, the term rate of climb indication can also be used to describe this feedback. No matter the term used, the goal of normal acceleration feedback is to provide pilots with accurate and timely information about their aircraft's altitude and ascent/descent rate to help maintain safe flight operations.
