Can weather radar images and terrain images be displayed on ND at the same time?【单选题】

A, can

Can't

If the weather radar shows that the echo is particularly strong, the light point is particularly bright, and it is a red zone, indicating that a strong ( ) aircraft must not enter, and corresponding circling measures should be taken.【单选题】

Cumulonimbus cloud

Heavy fog

Hail

Rain and snow

Is it true that in-flight weather radars should periodically perform manual scans to enhance weather information and then set the inclination to go back to automatic?【单选题】

TURE

FALSE

Does the weather radar system use signals provided by the IRS?【多选题】

USE

Not USE

When you must fly parallel to a series of thunderclouds, you should choose to fly on the upwind side of the cloud body (away from the forward direction of the cloud). Try not to fly under anvil clouds, and try to avoid cirrus and cirrostratus clouds downwind from the top of a thunderstorm cloud, because although the radar may not echo, they may contain hail. Whether this statement is correct？【多选题】

TURE

FALSE

In the event of a thunderstorm ahead of the flight, the captain must take into account the weather radar, how many nautical miles before the thunderstorm, decide to turn around or return, and immediately report the decision to air traffic control.【多选题】

The requirements for the use of weather radar in air route flights, the following statement is most accurate?【单选题】

flying at night and the external light is insufficient, such as the cloud body condition is unknown, do not keep the radar often open

Intermittent adjustment of the radar antenna Angle helps to detect the threat of thunderstorms and weather activity at other altitudes

if you need PWS to provide wind shear alarm at 2300 feet RA, you must press on WXR switch or ND check WXR

Below 3000 meters (excluding the terminal area), the recommended distance to safely fly around the thunderstorm is ?【单选题】

Not less than 3 nautical miles

Not less than 5nautical miles

Regarding the description of weather radar, the following statements are correct: :【单选题】

weather radar can detect all kinds of clouds, fog, clear sky turbulence and other dangerous weather.

antenna TILT (TILT) will be affected by the aircraft pitch and slope Angle changes.

the turbulence function is only effective within 40 nautical miles, and is wet air turbulence.

As the altitude of the aircraft increases, the weather radar echoes of the thunderstorm cloud gradually change from red to green or black, and there is no need to consider circling.【单选题】

TURE

FALSE

The WXR-2100 radar has a quiet, simple cockpit philosophy: only threatening weather is shown, and non-threatening weather (how many feet below the aircraft are weather threats) is not shown?【单选题】

5000

6000

The inclination Angle set by the weather radar refers to:【单选题】

the Angle between the antenna beam center line and the horizon

the Angle between the antenna beam center line and the vertical axis of the aircraft

the Angle between the horizon and the vertical axis of the aircraft

The PAC ALERT function is only valid for thunderstorms in the ( ) range.【单选题】

40NM

80NM

100NM

What does a red spot within the boundary of a thunderstorm cell mean?【单选题】

A. There is A medium-high risk of lightening discharge（正确答案）

B. Strong turbulence risks exist

C. There is a risk of heavy precipitation

At 5100 meters, what is the recommended minimum distance to safely fly around a thunderstorm?【单选题】

5 nautical miles

7.5 nautical miles

10 nautical miles
