15 - Warning Systems Flashcards
- When does the MASTER CAUTION light illuminate?
When a caution occurs outside the normal field of vision of the Flight Crew
- What color lights require immediate attention of the Flight Crew?
Red
- What color lights require timely attention of the Flight Crew?
Amber
- How do Master Caution System alerts differ between single/simple and dual-channel
faults?
Single/simple faults do not illuminate the System Annunciator nor MASTER CAUTION lights
- What is the lowest elevation, relative to the aircraft, that red indicates on the terrain
display?
More than 2000 ft above
- The FLAP INHIBIT switch is used to inhibit which GPWS callout(s)?
TOO LOW FLAPS
- When is the “500” RA callout provided?
-An approach other than ILS, or
-More than 2 dots off LOC or GS, or
-Backcourse approach
- What is the reactive windshear alert provided by the GPWS?
Aural warning “Windshear! Windshear!” and red “WINDSHEAR” displayed on both PFDs
- What does an amber ROLL/YAW ASYMMETRY on the PFD indicate?
The autopilot has reached 75% of its total roll authority
- How is the radar selected on?
By selecting WXR on the EFIS control panel
- What is provided when WX+T is selected on the Radar control panel?
displays weather radar returns and turbulence (manual mode) or weather radar returns and threats (auto mode); turbulence is displayed out to 40 nm for all selected ranges
- What type of windshear warning(s) does the weather radar provide?
Predictive
- Is radar turbulence detection capable of detecting clear air turbulence?
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.
- How long after activation does the PWS take until cautions or warnings can be provided?
Approximately12 seconds
- How is the Predictive Windshear System (PWS) activated?
- Thrust levers set for takeoff
Or - Pushing the WXR switch on the EFIS control panel
- What is the aural alert for a PWS Caution?
“WINDSHEAR AHEAD” during takeoff, below 1200 ft RA, close to and directly ahead
“GO AROUND, WINDSHEAR” during approach, below 1200 ft RA with windshear detected within 1.5 miles and directly ahead
“MONITOR RADAR DISPLAY” during takeoff and approach, within 3 miles and ahead
- How is the Runway Awareness and Advisory System (RAAS) activated?
RAAS operates without any actions required by the Flight Crew.
-Terrain/runway contained in the EGPWS db
-GPS available
-RUNWAY INHIBIT switch in NORM
- How are Resolution Advisories (RAs) displayed on the PFD?
Solid red box on ND
- What is the indication of a Traffic Advisory (TA)?
Amber dot on ND
- What is the difference between the amber MAINT light on the aft overhead panel and the magenta MAINT box on the MDS SYS page?
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
