Answer 6

+/- 4000ft of Flightpath

Question 7

Flightpath weather on the RDR-4000 weather radar is based upon what?

Answer 7

Vertical rate, groundspeed and extrapolated to 60nm’s

Question 8

Flying at FL 360 and a red cell appears on the weather radar. You should avoid this area by

Answer 8

Flying on the upwind side and clear of the red area by at least 20nm’s

Question 9

How does the RDR-4000 weather radar help weather avoidance at higher levels?

Answer 9

It automatically increases gain at higher levels to help identify weather

Question 10

In the climb below 6000ft with the RDR-4000 weather radar which of the following is true?

Answer 10

The upper limit for displaying flightpath weather is always 10,000ft

Question 11

Is a serviceable weather radar required for dispatch?

Answer 11

No, provided the aircraft is operated during day VMC

Question 12

On Approach, if you cannot get around a thundershower?

Answer 12

Avoid the approach if within 3nm of the field

Question 13

On the RDR 4000 weather radar panel, the gain control?

Answer 13

MIN reduces gain, requiring greater intensity levels to display red

Question 14

On the RDR-4000 weather radar which of the following is true?

Answer 14

Flightpath weather always takes precedence over secondary weather

Question 15

On the RDR-4000 weather radar, secondary weather is displayed as?

Answer 15

A hatched area

Question 16

On the RDR-4000 weather radar, the 3D volumetric buffer?

Contains a worldwide terrain database and removes ground returns from the weather returns

Question 17

On the RDR-4000 weather radar?

Answer 17

There is no tilt control feature on this weather radar

Question 18

Question text

The only selection modes where you will get a WX radar return on the ND inflight are:

Answer 19

WX & WX/TURB

Question 20

The returns from a weather radar?

Answer 20

Give an indication of possible turbulence and hail depending on colour

Question 21

The weather radar can detect?

Answer 21

Sufficiently sized water drops

Question 22

Weather radar annunciation ‘WXR ATT’ on the ND indicates?

Answer 22

Loss of attitude stabilisation for antenna

Question 23

What is the preferred tilt setting for T/O and landings?

Answer 23

4 to 5 degrees up - to prevent excessive ground returns and see and avoid bad weather on the climb path ahead

Question 24

What is the primary function of the weather radar?

Answer 27

Only that associated with a horizontal flow of precipitation with velocities of 5 or more meters per second toward or away from the radar antenna

Question 28

When deviating around a thunderstorm?

Answer 28

Deviate to the upwind side

Question 29

When looking above the freezing level in a radar return which of the following is true?

Answer 29

The strength of returns is reduced and so gain can be increased to compensate

Answer 30

320 nm

Question 31

When ‘TEST’ function is selected on the radar control panel, this?
