Contains autopilot flight director system F/D) and auto throttle system (A/T)
MCP
Mode control panel
AFDS consists of
Three autopilot flight director computers (AFDCs) and a MCP
FMA
Flight mode annunciator
LNAV
Lateral navigation. Simply azimuth navigation without vertical guidance.
ASTU
Automatic stabilizer trim unit. Aircrafts elevator position feed into ASTU, allowing ASTS TO CORRECTLY TRIM THE AIRCRAFT

the ADI (attitude director indicator) and HSI (horizontal situation indicator) Boeing
Primary flight display PFD & navigation display ND Airbus.
Also contains;
- control panel symbol generator so that drive signals may be switched to either the left or right display units.
- remote light sensor unit
PFD
Primary flight display
ND
Navigation display
EADI
Electronic attitude director indicator. Also known as PFD
EHSI
Electronic horizontal situation indicator also known as ND
HUD
Head Up Display.
System comprised of
HUD computer,
- overhead unit projector,
- a combiner
- a control panel
- an annunciator panel
EVS
Enhanced vision system.
both long wave and short wave Infrared camera for early detection of visual references.
Decreases operating costs by mitigating go rounds
SVS
Synthetic vision system.
Uses high precision navigation, attitude, altitude, and terrain databases to create a realistic view of the outside world.
ECAM
Electronic centralized aircraft monitoring-airbus.
Incorporates all features of EICAS.
HAS HE ADDED FEATURE OF PROVIDING CREW WITH CORRECTIVE ACTIONS TO ANY FAULTS THAT MAY ARISE, AS WELL AS SYSTEM LIMITATIONS AFTER THE FAILURES
TAWS
Terrain awareness and warning system
GPWS
Ground proximity warning system
5 modes
1-excessive descent ride
2-excessive terrain closure rate
3 altitude loss after takeoff or go around
4- and safe to rain clearance with the aircraft not in landing configuration
5- aircraft too low during ILS approach
EGPWS
Newly developed with seven modes. 1-excessive descent ride 2-excessive terrain closure rate 3 altitude loss after takeoff or go around 4- and safe to rain clearance with the aircraft not in landing configuration 5- aircraft too low during ILS approach 6-bank angle & altitude callouts 7-windshear
Displays terrain up to 320 nautical miles away, also provides warning of 60 seconds before impact with terrain
TCAS
Traffic collision avoidance system
-TCAS II most common. Provides traffic advisories TA and resolution advisories RA.
ABLE TO COPE WITH THE TRAFFIC DENSITY OF 24 AIRCRAFT WITHIN A 5-MILE RANGE. WILL COORDINATE ESCAPES FROM UP TO THREE AIRCRAFT
SMYD
Stall Management Yaw Dampener.
Regulatory margin for activation of stall warning system is 5% above stall speed (1.05Vs)
RWS
Reactive windshear system
Detection takes place when aircraft penetrates windshear condition
PWS
Predictive Windshear system
The system is a part of the weather radar system.
Uses doppler to detect disturbed air ahead of the aircraft
CVR
Cockpit voice recorder.
Effective 10th of may 2019. CVR RECORDING TIME INCREASED FROM 30 MINUTES TO 2 HOURS.
Connected to aircraft power, also has backup battery.
FDR
Flight data recorder.
New Zealand aviation legislation states it must be capable of recording and storing 25 hours of data in digital form.
Must be fully automatic, recording from engine startup to shutdown.
AIDS
Aircraft integrated data system
AHRS
Attitude heading reference system.
contains three rate gyros to measure angular aircraft motion in the pitch roll and Yaw axis. Three accelerometers to measure aircraft linear motion along longitudinal, lateral and vertical axis of the aircraft.
