AMT 2102 - Midterm M3 & M4

Electronic Instruments

Electronic Instruments

PRIMARY FLIGHT DISPLAYS (PFD)

NAVIGATION DISPLAYs (ND)

Strap Down

system contain no moving parts

Electronic Flight Instrument (EFIS)

Reduces instrument panel clutter by combining several instruments into one unit

Offer a moving map display with superimposed weather radar information

Center Symbol Generator

used as a redundancy check between the let and right systems

Symbol Generator

receives signals from the various instruments and navigational sensors located throughout the aircraft

Weather Radar Receiver/Transmitter

receives signals from the aircraft’s radar antenna and send information to both the pilot and copilot’s symbol generators.

Display Controller

allows the pilot to select the appropriate system configuration for the current fight situation

Advantage Of Display Controller

Greatly increased reliability

Reduced maintenance costs

Electronic Attitude Director Indicator (EAD)

Known as gyro horizon or artificial horizon Informs the pilot of the aircraft orientation relative to earth’s horizon

Primary instrument for fight in instrument meteorological conditions

Presented in the unit degrees

Electronic Horizontal Situation Indicator (EHSI)

Evolved version of the horizontal situation indicator, which was born from the gyroscopic direction indicator or directional gyro

Heading Indicator

Useful Navigational information as possible

Electronic Systems Monitoring Displays (ESMD)

EFIS is a fight deck instrument display system that displays fight data electronically rather than electromechanically

EFIS models used cathode ray tube displays, but liquid crystal displays are now more common

Electronic Centralized Monitor (ECAM)

Known as engine indicating and crew alerting system (ElCAS)

Displays concerning aircraft systems and also failures

Displayed corrective action to be taken by the plot

Produces messages detailing failures and list procedures to undertake to correct the problem

Engine Indicator and Crew Alerting System (EICAS)

Key function of glass cockpit system, which replaces all analog gauges with systems driven electronic displays

Used for navigation and orientation displays

Provide aircraft fight crew with instrumentation and crew annunciations for aircraft engines and other

EICAS equipped aircraft the Recommended remedial action” is called checklist

Outside Air Temperature (OAT)

To calculate true airspeed

Usually mounted near the top of the windscreen or out the side window beside the plot

Used in many calculations pertaining to flight planning

Consists of bimetallic type thermometer

Also called static air temperature

Clock

One of the most fundamental of instruments Used for timing flight maneuvers, and fuel consumption rate.

Checklist

EICAS equipped aircraft the Recommended remedial action” is called
