An Electronic Flight Instrument System (EFIS) is a flight deck instrument display system in which the display technology used is electronic rather than electromechanical. Early EFIS systems portray information using cathode ray tube (CRT) technology. … In some designs the two displays are integrated into one.
What is PFD and MFD?
An electronic flight instrument system (EFIS) is a flight deck instrument display system that displays flight data electronically rather than electromechanically. An EFIS normally consists of a primary flight display (PFD), multi-function display (MFD), and an engine indicating and crew alerting system (EICAS) display.
What is a symbol generator in aircraft?
A Symbol Generator (SG) is the device that receives the data from the airframe sensors and serves as the television transmitting station by processing the data for appropriate viewing. Aircraft with a five-tube EFIS will typically have three Symbol Generators.
What flight instruments are electrically powered?
In most light aircraft the Turn Coordinator (TC) is electrically driven. Usually the Heading Indicator (HI) and Attitude Indicator (AI) are vacuum driven. The three Gyro instruments, Attitude Indicator, Directional Gyro and Turn and Bank Indicator are ‘gyro’ driven.
What are the 5 primary mechanical displays a primary flight display PFD can replace?
PFDs provide increased situational awareness (SA) to the pilot by replacing the traditional six instruments used for instrument flight with an easy-to-scan display that provides the horizon, airspeed, altitude, vertical speed, trend, trim, rate of turn among other key relevant indications.
What are the four steps to basic attitude instrument flying?
Four steps (establish, trim, cross-check, and adjust) have been developed in order to aid in the process. Any time the attitude of the aircraft requires changing, the pilot must adjust the pitch and/or bank in conjunction with power to establish the desired performance.
What does EFIS mean?
An Electronic Flight Instrument System (EFIS) is a flight deck instrument display system in which the display technology used is electronic rather than electromechanical. Early EFIS systems portray information using cathode ray tube (CRT) technology.
What is Eadi?
The EADI is an advanced version of attitude and electric attitude indicators. One such system, the electronic flight instrument system (EFIS), uses a cathode ray tube EADI display driven by a signal generator. …
What is the purpose of aircraft instrument system?
Instrument systems now exist to provide information on the condition of the aircraft, engine, components, the aircraft’s attitude in the sky, weather, cabin environment, navigation, and communication.
What control does the EFIS control panel provide?
What control does the EFIS Control Panel provide? Explanation: The EFIS Control Panel (EFIS CP) provides the means for the flight crew to control the graphical and textual FMS data that appear on the ND and PFD. Control over flight plan and performance is given by MFD. Navigation through the pages is by KCCU.
What are the 3 gyroscopic instruments?
Together with the pitot instruments — airspeed indicator, altimeter, and vertical-speed indicator — the gyro system allows precise and safe trespass through the clouds.
What are the 3 categories of aircraft instruments?
There are three basic kinds of instruments classified by the job they perform: flight instruments, engine instruments, and navigation instruments. There are also miscellaneous gauges and indicators that provide information that do not fall into these classifications, especially on large complex aircraft.
What tools do pilots use?
- Airspeed indicator.
- Vertical speed indicator.
- Magnetic compass.
- Attitude Indicator.
- Heading indicator.
- Turn indicator.
- Very-High Frequency Omnidirectional Range (VOR)
What are the 6 basic flight instruments?
These six basic flight instruments are the following:
- Altimeter (Pitot Static System)
- Airspeed Indicator (Pitot Static System)
- Vertical Speed Indicator (Pitot Static System)
- Attitude Indicator (Gyroscopic System)
- Heading Indicator (Gyroscopic System)
- Turn Coordinator (Gyroscopic System)

How do you read an altimeter?
Read the numbers on the drum, then look at the pointer and add the 100s and 20s to the numbers on the drum to get your altitude. For example, if the drum reads 6000, and the pointer is at the 2nd line past the 2, then you would read it as 6000+200+40=6240. Your altitude is 6240 feet.
