15 - Warning Systems

Question 1

1. When does the MASTER CAUTION light illuminate?

Answer 1

When a caution occurs outside the normal field of vision of the Flight Crew

Question 2

2. What color lights require immediate attention of the Flight Crew?

Answer 2

Red

Question 3

3. What color lights require timely attention of the Flight Crew?

Answer 3

Amber

Question 4

4. How do Master Caution System alerts differ between single/simple and dual-channel faults?

Answer 4

Single/simple faults do not illuminate the System Annunciator nor MASTER CAUTION lights except when MC Recall is pressed

Question 5

5. What is the lowest elevation, relative to the aircraft, that red indicates on the terrain display?

Answer 5

More than 2000 ft above

Question 6

6. The FLAP INHIBIT switch is used to inhibit which GPWS callout(s)?

Answer 6

TOO LOW FLAPS

Question 7

7. When is the “500” RA callout provided?

Answer 7

-An approach other than ILS, or
-More than 2 dots off LOC or GS, or
-Backcourse LOC approach

Question 8

8. What is the reactive windshear alert provided by the GPWS?

Answer 8

Aural warning “Windshear! Windshear!” and red “WINDSHEAR” displayed on both PFDs

EXTRA CREDIT:
Windshear alerting is active under the following conditions:
• During takeoff, from rotation until 1500’ AGL
• During approach, from 1500 ft AGL to 10’ AGL
• During a missed approach until 1500’ AGL is reached

Question 9

9. What does an amber ROLL/YAW ASYMMETRY on the PFD indicate?

Answer 9

The autopilot has reached 75% of its total roll authority

Question 10

10. How is the radar selected on?

Answer 10

By selecting WXR on the EFIS control panel

Question 11

11. What is provided when WX+T is selected on the Radar control panel?

Answer 11

displays:
- weather radar returns + turbulence (manual mode)
- weather radar returns + threats (auto mode)

• turbulence is displayed out to 40 nm for all selected ranges

Question 12

12. What type of windshear warning(s) does the weather radar provide?

Answer 12

Predictive

Question 13

13. Is radar turbulence detection capable of detecting clear air turbulence?

Answer 13

No, Flight Crews must continue to rely on traditional windshear avoidance methods as the weather radar is not capable of supplying predictive windshear in clear air.

Question 14

14. How long after activation does the PWS take until cautions or warnings can be provided?

Answer 14

Approximately 12 seconds

Question 15

15. How is the Predictive Windshear System (PWS) activated?

Answer 15

• Thrust levers set for takeoff
  Or
• Pushing the WXR switch on the EFIS control panel

Note: PWS activates automatically in flight below 2300 ft RA (predictive windshear alerts are issued below 1200 ft RA)

Question 16

16. What is the aural alert for a PWS Caution?

Answer 16

“MONITOR RADAR DISPLAY” is the only aural PWS Caution. This alert sounds during takeoff and approach, with a detected windshear within 3 miles and ahead, and there will be a commensurate visual alert showing you where the system detected the windshear to help you avoid it.

Question 17

17. How is the Runway Awareness and Advisory System (RAAS) activated?

Answer 17

RAAS operates without any actions required by the Flight Crew.
-Terrain/runway contained in the EGPWS db
-GPS available
-RUNWAY INHIBIT switch in NORM

Question 18

18. How are Resolution Advisories (RAs) displayed on the PFD?

Answer 18

Red lines to stay outside of

Question 19

19. What is the indication of a Traffic Advisory (TA)?

Answer 19

Amber dot on ND

Question 20

20. What is the difference between the amber MAINT light on the aft overhead panel and the magenta MAINT box on the MDS SYS page?

Answer 20

The amber MAINT light on the aft overhead panel indicates a system fault exists that must be reviewed by maintenance
The magenta MAINT indication, visible on the top right of the DU, when SYS switch is selected on the ground, is normal and not an indication of a malfunction

Question 21

EXTRA CREDIT
The GPWS provides BANK ANGLE alert when the roll angle exceeds _____, _____, and _____?

Answer 21

-When aircraft is 5-30’ AGL; Back angle >10

-When aircraft is 30-130’ AGL; Variable Back angle between 10 and 35

-When aircraft is >130’ AGL; Back angle >35

Question 22

EXTRA CREDIT
When does the MASTER CAUTION light illuminate for a single/simple fault?

Answer 22

Master Caution Recall
