Rev 2 Flashcards
Receives various data from aircraft systems and parameters from some sensors.
Acquisition unit
Databus to the flight recorder for logging flight data
ARINC 717
Use for accident investigation
ELT and CVR
This difference between true and magnetic north is called
Variation
It compares the actual attitude of the aircraft and the commanded attitude and then controls it
Inner loop
What is the Autothrottle Computer?
TCC (Thrust Control Computer)
How will the pilot ensured that the transmission is successful
Sidetone
What is the heart of SATCOM?
Satellite Data Unit
Provide Signal for WX Radar for Antenna Stabilization
IRU (Inertial Reference Unit)
Difference between the heading and track
Drift
Amber - 1300 hertz - 1km from runway
How many minutes can we align IRU (Inertial Reference Unit)?
10 mins
Antenna that receives Morse code
Sense Antenna
An Example of a common ethernet bus interconnection for aircraft data network
ARINC 629
is a card file containing cards that generate visible and audible flight deck warnings.
MAWEA (Modularized Avionics Warning Electronic Assembly)
Related to flight crew function
DEU B – middle line
Related to passenger system function
DEU A – top line
CDSS (COCKPIT DOOR SURVEILLANCE SYSTEM) components
3 Cameras (entrance area), 1 CDSS Controller and Display
A Vertical speed indicator uses what pressure
Static Pressure
The assigned instruments for Aircraft Monitoring
EICAS or ECAM
actual ambient air temp
SAT (Static Air Temperature)
sum of ambient air temp generated by air compression
TAT (Total Air Temperature)
RAM air effect increasing the temperature of the air
RAM Rise
When can you erase the complete recording of CVR?
aircraft is on the ground and the parking brake is set
Located at center post between front windshields?
Standby Compass
One-way transmission. Have a dedicated transmitter and receiver. Data travels in one direction only
Simplex
When the aircraft path deviates below the glideslope beam during a front course ILS approach?
MODE 5: Below Glide Slope
GPS uses what kind of frequency?
1575.42 MHz approx. 13 meters
Alert callouts when a/c descends predefined altitude, decision height minimums or bank angle
MODE 6: Call Outs
Improves dynamic stability of aircraft. Controls rudder to dampen dutch roll oscillations during the entire flight?
Yaw Damper
Allow high data transmission rates which is necessary for normal satcom operation
High gain antennas
400m runway visibility at a height of 100 ft
Category 2
is a radio navigation system that receives radio signals in the frequency band of 190 to 1750khz from ground stations.
ADF (Automatic Direction Finder)
Where bearing and heading info is presented
RMI (Radio Magnetic Indicator)
Operates in a frequency range of 962 to 1213
MHz and measures the slant distance from the aircraft to ground station.
DME (Distance Measuring Equipment)
Transmit test results or maintenance reports to the airline maintenance centre.
CMCS (Central Maintenance Computer System)
It delivers information to the maintenance personnel.
CMS (Central Maintenance System)
is the component where you make frequency selections for the VHF and HF radio communication systems.
RMP (Radio Management Panel)
allows communication over distances up to 200 nm (nautical miles). It is also used by navigation systems like the VOR and ILS.
Band is between 30MHz – 300 MHz
VHF (Very High Frequency)
