Warning Systems

Question 1

What does the PSEU light indicate in flight?

Answer 1

Inhibited from TL advance to 30’’ after landing

Question 2

What could a PSEU light after landing indicate?

Answer 2

Overwing exit fails to disengage lock (the PSEU light will trigger an amber
MC)

Question 3

What types of warnings are available to the crew

Answer 3

Aural, visual & tactile

Question 4

What do the alert colours mean

Answer 4

Red = ‘’warning’’ required immediate attention Amber = ‘’caution’’ requires timely attention
Green = shows a fully extended or functioning state
Blue = information, pwr avail, valve position, status or transition Dim blue = system is in the caption config/position
Bright blue = system not in the caption config/position
White = information

Question 5

Single channel faults are not show normally, how can you see them?

Answer 5

Pressing recall.

Question 6

When do you switch from the MEL CDL to the QRH?

Answer 6

Company procedure, MEL up to TO, QRH once in flt

Question 7

When will PASS OXY automatically deploy?

Answer 7

Cabin alt 14000ft

Question 8

How long does the PASS OXY last?

Answer 8

Circa 12 mins`

Question 9

Is PASS OXY automatically activated on drop?

Answer 9

No, one mask in each row has to be pulled down to trigger the chemical generator.

Question 10

Should you activate PASS OXY for smoke in the cabin?

Answer 10

No, it mixes with the cabin air so won’t help. The flt deck supply to the masks is direct so is needed with smoke/fumes.

Question 11

How can you distinguish between a TO CONFIG and CABIN ALT warning?

Answer 11

Both have an intermittent horn Most AC have red captions
TO CONFIG only on the ground
CABIN ALT only >10000ft`

Question 12

How is the crew warned of stall? Can it be cancelled?

Answer 12

Stick shaker. Yes, by pulling CBs only under direction from the QRH
following ‘airspeed unreliable’.

Question 13

When is the alt alerting system inhibited?

Answer 13

Flap >25 or GS captured

Question 14

What triggers a EGPWS ‘’DON’T SINK’’

Answer 14

Excessive height loss after TO or GA

Question 15

What would trigger a TO CONFIG warning?

Answer 15

On TL advance for TO:
-flap not 1-25, asymmetric or moving
-slats not configured, asymmetric or moving
-speed brake lever not down
-parking brake set
-Stab trim not in green TO band
-Spoiler control valve open giving hyd pressure to gnd spoiler interlock valve

Question 16

When will the landing gear horn sound and can it be canx?

Answer 16

Flap TL angle RALT
0-10 <20 or <34 OEI 200-800ft Yes
0-10 <20 or <34 OEI <200ft No
15-25 <20 or <34 OEI Any No
30-40 Any Any No

Question 17

If the wx radar isn’t selected on before TO do you lose windshear
protection?

Answer 17

No, but yes. Automatically selected on as TLs set to TO thrust, but circa 12
sec delay until returns can generate a warning.

Question 18

Can the wx radar detect all windshear activity?

Answer 18

No. Requires particles (dust/water) in the air

Question 19

When are predictive windshear alerts available?

Answer 19

Cautions +/-30 deg out to 3nm
‘’MONITOR RADAR DISPLAY’’ amber ‘WINDSHEAR’ on ND
Warnings on gnd+/-0.25nm out to 3nm
‘’WINDSHEAR AHEAD’’ = STOP if below V1. red ‘WINDSHEAR’ on ND and PFD
Warnings in air +/-0.25nm out to 1.5 nm
‘’GO AROUND WINDSHEAR AHEAD’’ red ‘WINDSHEAR’ on ND and PFD

Question 20

When is reactive windshear warning available?

Answer 20

<1500ft RALT ‘’WINDSHEAR’’ calculated based on GPWS
(reactive cautions not enabled on company fleet)

Question 21

When are predictive windshear alerts inhibited?

Answer 21

Below 2300ft detection starts
Below 1200ft warnings and cautions active To avoid overloading TO phase:
Below 400ft and >80 kts limited to warnings only
Below 50ft and >100kts all alerts inhibited

Question 22

Scan width of WX radar?

Answer 22

Normally +/- 90 deg, when predictive windshear active +/- 60 deg

Question 23

WX radar colours?

Answer 23

Green, amber, red based on increasing density. (Magenta = predicted turbulence)

Question 24

WX radar turbulence?

Answer 24

WR+T = horizontal droplet movement of >5 meters per second Displayed/detected to a max of 40nm regardless of scale selected

Question 25

CVR details?

Answer 25

Looped 120 mins
4 channels (Capt, FO, observer and area mic) Starts when selected on or automatic at 1st engine
Stops after 2nd engine shut down + 5 mins

Question 26

Can you erase CVR?

Answer 26

Yes, on gnd, parking brake set, press and hold ‘erase’ for >2 secs

Question 27

FDR details

Answer 27

Looped 25hrs
Starts on 1st engine start
Stops on 2nd engine shut down

Question 28

EGPWS terrain, what do the colours mean?

Answer 28

Dotted green >500ft below Dotted amber -500ft to +2000ft Dotted red >2000ft above
Solid amber 40-60sec to collision ‘’CAUTION TERRAIN’’
Solid red 20-30 sec to collision ‘’TERRAIN TERRAIN PULL UP’’

Question 29

TCAS ‘scan’ area?

Answer 29

Normal +/-2700ft
Above +7000ft to-2700ft
Below +2700ft to -7000ft

Question 30

When is TCAS inhibited?

Answer 30

Above 1500ft no restrictions
Below 1500ft ‘increase descent’ RAs inhib Below 1100ft all ‘descend’ RAs inhib Below 1000ft all RAs inhib, TA only
Below 500ft all TAs inhib
Windshear and terrain warnings override all TA/RAs

Question 31

When should you select TA only?

Answer 31

When prescribed in the QRH (when your performance is degraded reducing your ability to climb)

Question 32

What do the ‘eyebrows’ indicate?

Answer 32

PLI (Pitch Limit Indictor) the max nose up attitude before reaching the stall
-slow speed & flap up
-flap not up at any speed

Question 33

When with the seat belt signs come on/off at ‘AUTO’?

Answer 33

Come on when gear OR flap is extended Goes off when gear AND flap is up

Question 34

When do the overwing exits lock?

3/4 cabin doors closed & either engine running & (A-G logic in the air, or both TLs advanced)

Question 35

When do the overwing exits unlock?

Answer 35

2/4 cabin doors open & engines off & (A-G logic on gnd or either TL at closed) or DC power lost

Question 36

When is the alt alerting sequence

Answer 36

900-750ft to acquisition, alts will be boxed and bold white Once acq if 2-300ft from level amber flashing boxed alt
(inhibited if flap >25, or GS captured
