11.5.2 Avionics Systems Flashcards
4 systems of auto flight system
- command
- error sensing
- correction
- follow up
Flight director components
• delta or wing symbols
• steering bars
This system is like an attitude indicator
Auto throttle
• servo moves the thrust levers
HF communication
• allows for long distance voice communication between different aircraft
What reflects radio waves back to the earth
Ionosphere
VHF communication
• used for short range voice and data communication
SELCAL
• provides aural and visual indications of the calls received from ground stations
• uses HF and VHF systems
•
SATCOM
• worldwide mobile communications system providing voice and data communication services to and from the aircraft
GES
• ground earth station
•
ACARS
- Aircraft communication addressing and reporting system
* used to transmit and receive automatically or manually generated reports or messages to or from a ground station
Audio integrating system
Allows communication between flight crew ground crew etc
Flight interphone
Communication between cockpit crew if window breaks
Cabin interphone
Communication between pilots and flight crew
ELT
Emergency locator transmitter
How long does CVR record
30 mins
FDR
- Flight data recorder
* parameters stored for 25 to 50 hours
ADF
- automatic direction finder
* radio navigation aid
ILS
Instrument landing system
What does ILS use
Glide slope and localiser beam
VOR
Very high frequency omni directional range system
What is a marker
Navigational aid which determines the the distance between the aircraft and runway threshold
Radio altimeter
Gives the height of aircraft above terrain
DME
Distance measuring equipment
TCAS
Traffic collision avoidance system
ACAS
Airborne collision avoidance system
