Avionics Flashcards
EAWS
Safety concerns with Avionics
To not stand in front of Radars, to prevent radiation.
Barometric Altimeter
Uses pitot-static pressure to indicate altitude above sea level.
Radar Altimeter
Uses echos to determine altitude above ground level
VHF/UHF
Very-High Frequency and Ultra-High Frequency; To communicate with other a/c, ground stations, shipping traffic, and coastal stations.
What is IAS and its purpose
Intercommunication Audio System; provides routing of audio signals between the cockpit, ground crew, and rear cockpit
What is TACAN and its purpose
Tactical Air Navigation; relative bearing and slant range distance to a ground station or similarly equipped a/c. Ex NAS Oceana.
What is INS an its purpose
Inertial Navigation System; detects a/c motion and provides acceleration, presents the position.
Define GPS
Global Positioning System; receives information from a satellite source, provides pilot an updated preset position time.
What is ARI and its purpose
Attitude Reference Indicator; self-contained pitch and roll attitude reference system.
What is ILS and its purpose
Instrument Landing System; Provides steering information to help the land.
Define RADAR
Radio Detection and Ranging; has target detection, designation, tracking, and navigation
Characteristics of Fiber Optics
Send signals, light, and efficient.
Advantages and disadvantages of using fiber optics
faster, lighter, and system performance. But easy to break, made of glass making it fragile.
Mission computers
To communicate and provide data conversion.
MIDS/JTRS
Multifunctional information distribution system links everything in one system.
