WARNING SYSTEMS

Question 1

Recall the flight deck indications of Windshear: (Reactive Windshear
System

Answer 1

Increasing Performance - Amber “WINDSHEAR” appears on the PFDs
and FMA speed/altitude windows. An aural warning tone and three
cycles of “Headwind Shear” sound.
VOL.2
15.20.3 52
 Decreasing performance - Red “WINDSHEAR” appears on the PFDs
and FMA speed/altitude windows. An aural warning tone and three
cycles of “Tailwind Shear” sound

Question 2

Recall how windshear guidance is activated on approach: (Reactive
Windshear System)

Answer 2

Guidance will not come on during approach unless a go-around is
initiated by pushing the GA button or advancing the throttles past the
95% GA thrust limit after windshear is detected.
 Once the GA is initiated, the ATS, if off, will engage and advance to
maximum GA thrust. The FD, if off, will pop up automatically. Guidance
will continue until the windshear condition no longer exists

Question 3

Recall how Electronic Instrument System (EIS) Alerts are presented and
prioritized:

Answer 3

Level 3 Alerts – Boxed RED
Emergency operational conditions that require immediate crew awareness
and immediate corrective action by the crew.
 Red MASTER WARNING lights illuminate.
 Boxed red alert on the EAD with a red triangle in the first position
Level 2 Alerts – Boxed Amber
Abnormal operational system conditions that require immediate crew
awareness and subsequent corrective action
 Amber MASTER CAUTION lights illuminate.
 Boxed amber alert on the EAD.
Level 1 Alerts - Amber
May require maintenance prior to takeoff, a logbook entry, a confirmation of
desired system configuration, or a flight crew action but not a checklist
procedure.
 Amber MASTER CAUTION lights may illuminate.
 Amber alert appears on the EAD, SD page, or STATUS page.
Level 0 Alerts – Cyan
Generally operational or airplane systems status information.
 A cyan alert on the EAD.
 Alert is positioned above the space for reminder messages. The
latest level 0 alert is added to the top of the level 0 alerts.

Question 4

Recall the indications of an overspeed condition:

Answer 4

AURAL WARNINGS - Clacker followed by voice: “OVERSPEED” or
“SLATOVERSPEED.”
 VISUAL - Airspeed tape on PFD amber or red. CONDITION -
a. Overspeed: Vmo or Mmo exceeded (red).
b. Slat Overspeed: Over 280 knots with slats extended (amber)

Question 5

Explain the function of the Pitch Limit Indicator (PLI):

Answer 5

Indicates difference between airplane angle-of-attack (AOA) and
stickshaker AOA.
 Turns red at stickshaker

Question 6

Explain the significance of a TCAS Resolution Advisory (RA):

Answer 6

A Resolution Advisory (RA) appears on the PFD and ND when a threat
airplane is about 25 seconds from the Closest Point of Approach
(CPA).
 On the ND, the RAs are depicted as red squares
Two types of RAs:
 Corrective RAs recommend changing vertical speed with a green fly-to
zone on the PFD vertical speed display.
 Preventive RAs recommend not changing vertical speed with red
forbidden zones on the PFD vertical speed display

Question 7

Recall the significance of a TCAS Traffic Advisory (TA):

Answer 7

Traffic Advisories (TA) are amber circles on the ND representing
airplanes that are 40 seconds from the CPA.
 There is no requirement to change or monitor vertical speed but visual
acquisition of the threat airplane is required.
 The voice warning associated with a TA is “TRAFFIC, TRAFFIC”

Question 8

Recall the requirements associated with complying with a TCAS 
Resolution Advisory (RA):

Answer 8

Pilots are authorized to deviate from their current ATC clearance to the
extent necessary to comply with a TCAS resolution advisory (RA).
VOL. 1
L.10 54
 When TCAS voice message, “CLEAR OF CONFLICT” is announced,
the pilot must promptly return to the previous ATC clearance

Question 9

Recall the six basic modes of the Enhanced Ground Proximity Warning
System (EGPWS):

Answer 9

The system provides visual and aural warnings for the following conditions:
 Mode 1 - Excessive Descent Rate
 Mode 2 - Excessive Terrain Closure Rate
 Mode 3 - Altitude loss after takeoff
 Mode 4 - Unsafe Terrain Clearance
 Mode 5 - Descent Below Glide Slope
The GLIDESLOPE voice warning is generated and the BELOW G/S
light is illuminated.
 Mode 6 - Altitude Callouts/ Excessive Bank Angle Warning

Question 10

Explain the detection and alerting capabilities of the Predictive 
Windshear System (PWS):

Answer 10

The Predictive Windshear (PWS) detection function detects microburst
windshear hazard to provide visual and aural alerts during takeoff and
landing. PWS alerts consist of an ICON of red and black bands with
yellow boundaries showing location of any detected windshear on the
NDs, appropriate messages on the PFDs, and aural alert through
cockpit speakers/headsets.
 PWS detection function is automatically activated in flight, regardless of
radar mode selection (including OFF), when the airplane is below 2,300
feet radio altitude.
 Cockpit alerts are generated when the airplane is below 1,200 feet AGL
and a microburst is detected.
 During takeoff, warning alerts are inhibited from 100 knots airspeed
until reaching50 feet AGL.
 Alerts are inhibited below 50 feet AGL during landing

Question 11

Recall the function of the TERRAIN switch on the Enhanced Ground
Proximity Warning System (EGPWS) panel:

Answer 11

Push - Illuminates blue OVRD legend and disables the enhanced
functions. Basic EGPWS modes are not affected. Enhanced functions
can also be disabled automatically by the EGPWS

Question 12

Recall the conditions that will activate a Takeoff Warning

Answer 12

Brakes: Parking Brake Set
 Flaps not in agreement with setting entered into FMS
 Slats not in takeoff
 Spoilers not stowed
 Stabilizer not in green band
 Rudder Trim not centered

Question 13

Recall the indications associated with deviating or approaching a
selected altitude:

Answer 13

AURAL WARNINGS - C-chord followed by voice “ALTITUDE.”
 VISUAL - PFD altitude box turns amber or flashes.
 CONDITION - Deviating or approaching selected altitude

Question 14

Recall the conditions which would prevent a green takeoff or landing
checklist-complete box to be displayed in the essential items checklist
area:

Answer 14

The takeoff essential items checklist consists of the following ordered
list of conditions and boxed messages.
 When all takeoff conditions have been satisfied, a green takeoffchecklist-complete box is displayed in the essential items checklist
area.
CONDITION MESSAGE COLOR
STAB not in green STAB TRIM White
Rudder Trim not centered RUDDER TRIM White
Slats not in takeoff SLAT White
Flaps not in takeoff FLAP White
Park brake on BRAKES White

 The landing essential items checklist consists of the following ordered
list of conditions and messages.
 When all landing conditions have been satisfied, a green landingchecklist-complete box is displayed in the essential items checklist
area.
CONDITION MESSAGE COLOR
