Four Functions of the FMS
Performance
Radio
Navigation
SSPC
What does the SPDS do?
Controls various AC and DC loads throughout the airplane.
When can you erase CVR information?
Ground, door open, stationary.
Auto pop up of SFD occurs when?
P PFD failure U Unusual attitude B BPT I Instrument miscompare S SFD on the other side fails
Reasons for loss of terrain on SVS?
Doing a RA test within 15” of a EGPWS test
Operating without WGS84 information
BPT
Nose low or high attitude
What does T/O data p. 3 of 3 represent?
Minimum level off ht. 1 eng V2 clear of obstacles
Maximum level off ht. 1 eng V2 at the end of 10” for reference 0 and from the DER to see if we beat the SID
Reference 0 is 35’
Terrain Inhibit must be on when?
T Not in terrain database
R < 3,500’ runway
I No IAP
QFE ops t/o and landing w/o geometric altitude
What is the MWF? When do they switch channels.
It is the Fault Warning Computer, there are two.
They cycle on every power down as do the A/T’s.
If the CAS red X’s you can manually select the other FWC. This should have automatically occurred.
The geo-reference on a chart can be green or white, when?
Green when the approach comes out of the FMS, white otherwise.
When is a NUC check done?
Camera turns on
Flaps selected to 10
Pilot presses the button
When would you use H for an EVS setting and where would you see it in the HUD?
High probability of a missed approach
Four gains for EVS appearing in upper left corner of the HUD?
A auto
H high
L low
C clear
Airport and runway appear/disappear in the HUD at ______ feet?
Airport 2,000' Runway 350' A/P gone 325' Flarecue 100' R/W gone 60'
Issue with the EVS imagery?
Blooming
Misalignment
Thick clouds
Thermal crossover - temps close together
What on the approach chart indicates you can descend to 100’ above TDZE using EVS?
A published DA.
AFM Limitations 01-34-70
When does a g-load appear in the HUD?
Unusual attitudes
-1 to + 2.5g’s clean
What is EPU?
A measurement of how accurate the sensors are? Performance Based Sensor Selection System
VSD displays track when?
Track in green when under heading
No track presentation when under FMS track
Track in amber when EPU exceeded
Where does the SFD get its air data?
ADS #4, no air data on e-batts.
GPWS ORIDE capsule on glare shield does what?
Disables all modes except windshear.
Operating VMC near terrain.
RAD ALT capsule on glare shield does what?
All EGPWS callouts are inhibited except MINIMUMS and BANK ANGLE.
Might be used with an inop radar altimeter.
What does selecting INHIBIT do?
Inhibits most ambers and blues.
Amber exceptions are LPV Unavailable, lateral, and vertical cpl data invalid, auto brake off, auto brake disarmed, 5 CAT II’s.
AURALS ONLY
What happens when more than 12 red CAS messages want to post on the CAS 1/6?
Trim synoptic moves to the PFD.
Inhibit is cancelled when?
Above 400’ AGL on takeoff or after a go around once the gear is retracted.
