weather radar

Question 1

On arrival DAL. Number 2 for approach at 3000 feet. Airplane in front of you goes around for windshear. Will your weather radar give you a PWS alert for that windshear?

What are the priorities? how long should you delay?

Answer 1

No. Windshear conditions are detected below 1200 ft along and ahead of the aircraft flight path.

Windshear conditions often dissipate within 10-20 minutes. If the presence of windshear is confirmed, delay takeoff or do not continue approach.

Question 2

Departing south out of DAL on CURLO6 with convective activity in the area. A cell is drifting across your departure path. At 70 knots, you hear “monitor radar display.” what should you do?

Answer 2

Continue with the takeoff. Be prepared to execute the Windshear escape maneuver once airborne.

MONITOR RADAR DISPLAY: windshear within 3 miles and ahead of the aircraft is detected by weather radar.

Question 3

Are there different detection parameters between PWS caution and PWS warnings -800/-700?

Answer 3

WINDSHEAR-WINDSHEAR-WINDSHEAR-WINDSHEAR: excessive windeshear at the current aircraft position detected by GPWS. Enabled below 1500 RA.

WINDSHEAR AHEAD (TAKEOFF): windshear is close to and directly ahead of the aircraft. Enabled during takeoff and below 1200 RA>

GO AROUND, WINDSHEAR AHEAD: windshear within 1.5 miles and directly ahead of the aircraft detected by weather radar. Enabled during approach below 1200 RA.

Monitor radar display: windshear within 3 miles ahead. Takeoff ND APPROACH below 1200 ra

Question 4

Enroute to MCO there are isolated storms building around MCO. You turn on radar and it fails. What are your options?

Answer 4

Options include:
1. call dispatch for real time weather avoidance
2. Request the latest TS info from ATC
3. Call nearest FSS
4. Review the latest available weather reports, radar maps, sigmets
5. consult any other info sources regarding TS conditions

Question 5

What is the maximum distance that turbulence can be depicted on the ND for the RDR-4B and RDR-4000?

Answer 5

Regardless of range:
RDR-4B: 40 nm
RDR-4000: 60 NM

turbulence is displayed in magenta

Question 6

What is the significance of weather displayed with black stripes in the RDR-4000?

Answer 6

Black stripes designate secondary weather based on the current flight path

Question 7

FL260 and your radar indicates a TS in your flight path. What is the recommended distance to avoid radar echoes at this altitude?

Answer 7

When above 23,000 ft avoid all echoes by 20 nm. If possible, circumnavigate all echoes by flying on the upwind side.

Question 8

Radar shadows in the RDR-4000 are identified with magenta arcs via the REACT function. How would you identify a radar shadow with an RDR-4B?

Answer 8

Adjust the antenna tilt down to a position showing ground return on the outer third of the indicator. Radar shadows are the black areas at the outer extremity of the displayed range.

Question 9

Are there different detection parameters between PWS cautions and PWS warnings? MAX8

Answer 9

WINDSHEAR-WINDSHEAR-WINDSHEAR-WINDSHEAR: windshear is close to and directly ahead of the aircraft detected by weather radar. Enabled during takeoff below 1200 RA.

GO AROUND, WINDSHEAR AHEAD: windshear within 1.5 miles and directly ahead of the aircraft. Enabled during approach and below 1200 RA.

Windshear ahead (takeoff)

MONITOR RADAR DISPLAY: windshear within 3 miles and ahead of the aircraft. Enabled during takeoff and approach below 1200 RA.
