Instruments - Flight

The idea of combining flight data into integrated flight instruments began half a century ago to help reduce pilot workload. Integrating situation display with flight command information assists the pilot in reaching the destination safely and efficiently.

Such data is further utilized by the Autopilot system.

• Usually pitch and roll information is presented on the Attitude Indicator or Flight Director, while navigation or directional information is shown on the Course Indicator, often called the Horizontal or Navigation Situation Display.
• Knowing which systems are function correctly is key, so monitoring circuits were introduced to drive flags and annunciators in these flight instruments, advising the pilot of invalid information or a malfunction.
• What you see in these instruments is only a small part of the many associated transducers, gyros, computers and avionic boxes which drive them, and developing technology has reduced the weight and size of mechanical devices thus enabling even more features to be incorporated.
• In spite of mechanical complexity, the fact that much of this equipment is still in service after typically 30 years is a testimony of the high standards. Although EFIS or electronic flight instruments is appealing, until the higher costs become economical traditional electro-mechanical instruments will remain in service for a long time yet, providing they are properly maintained.

With technicians on staff having well over 40 years in instrument repair, the benefit of nearly half a century of experience in properly maintaining electro-mechanical components can be your advantage. Don't let the consequences of mistakes through lack of experience cost you.
