Read the text. AIRCRAFT INSTRUMENTS

Aircraft instruments are basically devices for obtaining information about the aircraft and its environment, and for presenting that information to the pilot in a concise form. Their purpose is to detect, measure, record, process and analyze the variables encountered in flying an aircraft. They are mainly electrical, electronic or gyro­ scope. They are concerned with the behaviors of the engines, the speed, height and attitude of the aircraft and its whereabouts. Instruments concerned with the whereabouts 'of an aircraft are navigation instru­ments and these are dealt with separately in Lesson 13. Lesson 12 is concerned with instruments that obtain and present information on flight (excluding whereabouts and direction), propulsion, fuel, air-frame, electrical and pressure systems. The history of the development of aircraft instruments shows a movement away from instruments that merely obtain and present information to those that automatically do something about the in­ formation they receive. For example, at one time an instrument would have told a pilot that his aircraft was nose-down and. it would have been left to the pilot to take corrective action manually if necessary.

Nowadays it is often the case that a pilot will "instruct" an automatic system, for example, to fly level, and the appropriate instrument will usually show the "instruction" is being "obeyed" and only exception­ ally that something is wrong because the automatic system has failed. A modern aircraft cockpit looks on first sight to consist of a be­wildering array of instruments that no human being could ever master or understand. It looks as though so much information presented si­multaneously could never be absorbed by a small team of two to four people with any certainty. However, Instrument panels are designed in such a way that instruments are grouped logically so that to a pilot it is an "open book".
