What is the service ceiling of FIS-B
FL 240
What does AO2A mean?
Automated observation augmented by a human observer
You are experiencing turbulence that momentarily causes slight, erratic, changes in altitude or attitude 1/3-2/3 of the time. How would you report it in a pirep?
Intermittent light turbulence
How would you classify occasional , intermittent, continuous turbulence by frequency of time
Occasional. Less than 1/3
Intermittent 1/3-2/3 of the time
Continuous More than 2/3
Frequency of lightning
Occasional-Less than 1 flash per min
Frequent- 1 to 6 per minute
Continuous - more than 6 per min
When does the descriptor for Snow go from Blowing (BLSN) to Drifting (DRSN) in a METAR?
At 6ft
When will a CWA be issued?
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
How far should your flight be away from severe thunderstorms?
20nm
Effect of moderate turbulence inside the cabin and aircraft indications
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.
How often are airmets and sigmets transmitted on FIS-B?
5 minutes upon request
What is the difference between BR and RA?
Mist is just fog with visibility greater than or equal to 5/8 sm vis. Rain is an actual precip
Light turbulence
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
Light chop
Turb that causes slight rapid and somewhat rythemic bumpiness without appreciable changes in altitude or attitude
Moderate turbulence
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
