Introduction to Aircraft Engine Instruments 1964 US Army Training Film TF46-3406 (Patreon)

Originally a public domain film from the National Archives or Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Aircraft Instrumentation

There are two parts to any instrument system—the sensing mechanism and the display mechanism. Information is relayed from the sensors to the indicators via electricity, or direct pressure sensing via pneumatic or oil-filler tubes. 

There are three basic kinds of instruments classified by the job they perform:

flight instruments

engine instruments

navigation instruments

There are also miscellaneous gauges and indicators that provide information that do not fall into these classifications, especially on large or complex aircraft. such as Flight control position, cabin environmental systems, electrical power, and auxiliary power units (APUs) for example, are all monitored and controlled from the cockpit. All may be regarded as position/condition instruments since they usually report the position of a certain moveable component on the aircraft, or the condition of various aircraft components or systems not included in the first three groups...

Engine Instruments

In a gas turbine engine, engine instruments generally indicate fuel flow and temperature indicators, as well as engine speed in percentage of normal shaft speed (N1 and/or N2). In a reciprocating engine, instruments generally indicate oil pressure and temperature, cylinder head temperature and exhaust gas temperature for one (usually the hottest-running) or sometimes all cylinders, and sometimes manifold absolute pressure, or MAP.

On the right are a set of old fashioned analog gauges, and on the left is a modern Engine-Indicating and Crew-Alerting System (w:EICAS) found on a modern airliner or small jet, which only displays the information the pilot needs to see. This also replaces the w:Annunciator panel found on older planes, where a system failure triggers the corresponding annunciator to illuminate, as well as either the Master Caution if an amber-coloured annunciator is triggered, and the Master Warning light if a red-coloured (critical) system annunciator is triggered...
