How do you squelch?
Press the com volume button for automatic squelch
Pressing the Nav volume button?
Idents the morse code
How do you know if a valid signal is picked up?
The 3 letter ident code will show along side

If one GDU fails what should happen?
Automatically enters revisionary mode if not press red display back at button of audio panel
How many batteries are there?
5
Main battery 24v 10Ah
Excitation battery 24v 1.3Ah
X2 ECU back ups 24V 1.3 Ah
1 non rechargeable Emergancy power
How do you engage/disengage the AP?
Press AP bottom left of AP panel
Can also disengage on the control column
AP control modes
VS - auto
HDG - will follow the PFD heading bug
NAV - maintain track on CDI with 2-3 dots
APR- with 2-3 dots . Glide slope
REV - not used
ALT - hold current imidiate level off
Arm shows it is outside
ALT ARM
With VS mode and aircraft climbing or descending the ARM button will capture the target altitude
PT
Pitch trim
Two arrows aircraft is in trim
No arrows trim failure
CWS
Control wheel steering
Disengages the pitch and trim clutches and momentarily disengages the autopilot
Slows pilot to move the aircraft and set new headings and satins without disengaging the autopilot
P R
If illuminating indicates it has been disabled or has failed
How long should alignment take on PFD?
1 min
Where can the GS be found?
Ground speed top of the MFD
What is FDE, HDOP
Fault detection and elimination
Horizontal dilution of precision - strength of config, or geometry on accuracy of data collected
Following a PFD failure what comms are available?
Comm2 only
RAIM prediction?
Is used to see wether RAIM will be available at a predicted time
What does RAIM do?
Ensures that the available satellite allows receiver to calculate a specified protection limit
Blue signal bar?
Green signal bar?
Hollow?
D?
Satellite locked on but not being used
Satellite being used to calculate positions
Collecting data
Being used for differential computations
HFOM
VFOM
Measures of horizontal and vertical position uncertainty, 95%
EPU
Error position uncertainty
Error indication outside of 95% probability
HDOP
Horizontal Dilution of Precision
Lower the number to he better accuracy
PROC key
IFR procedures Arrival procedure (STARs) App procedure (IAPs)
How can you set a BARO min?
Time/reference soft key
What does the volts on the system display read?
Volts from L and R main bus
What does the amps show on the system display?
The alternator loads
ADF/BFO
Beat frequency oscillator mode
Audible tone confirms signal reception
DME pairing HOLD
DME remains paired with the last selected Nav frequency
GND transponder
Does not allow mode a or mode c replies only replies to mode s (tas)
How do you enter a FLt ID
On the timer/reference page PFD
COM 1/2
Spilt coms
Both become transceivers
Pilot uses com 1
Co uses com 2
Joystick
Range know can be used to selected points on map
Airspace alerts
Found on the
MFD
Aux
System set up
How do we know the pitch trim system has bee. Disabled?
PT annunciation is displayed on the autopilot
Happens if pitch trim on control colum is held for longer than three seconds and only one part is moved
Nav or App arm
AP engaged whilst not within 2-3 dots and so the previous mode engages to capture the Nav signal first
If using a VOR the CDI may never line up as the autopilot heads towards the beacon not the designated radial
Differenc between ALT mode and Arm
Alt immediately capture the altitude and levels off
