Q

When does the descriptor for Snow go from Blowing (BLSN) to Drifting (DRSN) in a METAR?

A

At 6ft

17
Q

When will a CWA be issued?

A

Conditions meeting convective SIGMET criteria within 2 areas

Icing - moderate or greater
Turbulence - moderate or greater
Heavy precipitation
Freezing precipitation
Conditions at or approaching Low IFR
Surface winds/gusts >30 knots
Low Level Wind Shear (surface - 2,000 feet)
Volcanic ash, dust storms, or sandstorms
18
Q

How far should your flight be away from severe thunderstorms?

A

20nm

19
Q

Effect of moderate turbulence inside the cabin and aircraft indications

A

changes in your altitude or attitude, but your aircraft remains in positive control at all times. You’ll feel a definite strain against you seat belt or shoulder straps. And if you have unsecured objects in the cabin, they’ll become dislodged.

20
Q

How often are airmets and sigmets transmitted on FIS-B?

A

5 minutes upon request

21
Q

What is the difference between BR and RA?

A

Mist is just fog with visibility greater than or equal to 5/8 sm vis. Rain is an actual precip

22
Q

Light turbulence

A

The airplane will momentarily causes slight, erratic changes in altitude and or attitude

Inside the airplane people might feel a slight strain on seatbelts, unsecured objects may be displaced slightly

23
Q

Light chop

A

Turb that causes slight rapid and somewhat rythemic bumpiness without appreciable changes in altitude or attitude

24
Q

Moderate turbulence

A

Changes and attitude or altitude occur but the aircraft remains in positive control at all times. Causes variations on airspeed

In the cabin people feel a definite strain on the seatbelts. Unsecured objects are dislodged. Food service and walking is difficult

25
Q

Moderate chop

A

Rapid bumps or jolts without changes in attitude and altitude

26
Q

Severe turbulence

A

Causes large, abrupt changes in altitude or attitude. Causes large variations in indicated airspeed. Aircraft may momentarily be out of control.

In the airplane occupants are forced violently against seatbelts. Unsecured objects are tossed about. Services and walking are impossible

27
Q

Extreme turbulence

A

The airplane is tossed around and is impossible to control. It may cause structural damage
