An electronic instrument system for modern turbine-powered aircraft that senses engine parameters and displays them on one of two multicolor display units on the instrument panel.
The EICAS evaluates changes in any of the parameters and, based on programmed limits, warns the flight crew of any changes that could signal an impending problem. Only vital information is shown at all times, but any of the sensed parameters are automatically displayed when they fall outside of their allowable range of operation.
Industry:Aviation
An electronic instrument system that monitors the functions of the entire aircraft and displays the information on two color multifunction displays in the aircraft cockpit.
The left-hand display shows the status of the systems, and the right-hand display shows diagrams and additional information about the system shown on the left-hand display.
Industry:Aviation
An electronic instrument that determines the logic level, or state, (0 or 1) at specific points in a digital circuit.
Industry:Aviation
An electronic instrument that measures the frequency and amplitude of the various components of a complex electromagnetic wave.
Industry:Aviation
An electronic instrument that produces a permanent record of the values of electrical current as it changes with time. Transducers produce electrical signals that relate to the mechanical movement being measured. These signals are recorded on a time base in such a way that they produce a graphic record of the way the mechanical movement changes with reference to time.
Industry:Aviation
An electronic instrument used to find the resonant frequency of an inductive-capacitive (LC) tuned circuit. The grid dip meter contains a variable-frequency oscillator and an indicating instrument. The probe of the grid dip meter is held near the circuit being examined, and the oscillator is tuned until the meter dips. The frequency produced by the oscillator when the meter dips is the resonant frequency of the circuit.
Industry:Aviation
An electronic navigation instrument that combines a magnetic compass
Industry:Aviation
An electronic navigation system in which the position of the aircraft is determined by the angular relationship between the aircraft and a series of orbiting satellites.
Industry:Aviation
An electronic navigation system that is approved for use under instrument flight rules as a primary means of navigation and has at least one source of navigation input, such as inertial navigation system, global positioning system, Omega/very low frequency, or LORAN C.
Industry:Aviation
An electronic navigation system used by both military and civilian aircraft. The name VORTAC is the combination of the names of two types of navigation equipment: VOR, very-high-frequency omnirange navigation equipment, and TACAN, a military pulse-type tactical navigation system. VOR and TACAN equipment are colocated at a VORTAC station, and signals from both systems are transmitted simultaneously.
Military aircraft use the TACAN system for determining their direction and distance from the VORTAC station. Civilian aircraft determine their direction from the station by the VOR and their distance from the station by the distance-measuring portion of TACAN. This distance is shown in the aircraft by the distance measuring equipment (DME).
