Three Astrisks
Moderate Snow
What is microburst?
intense small-scale downdraft produced by a thunderstorm or rain shower
Microburst timing and coverage area
up to 15mins and covers 2-5 miles diameter
Interpert WS005/27050kt
Windshear at 500 AGL wind 270 50
There is visible moisture, expect?
structural icing
Wind-shear with string tailwind. How to adjust power
Decrease power, Further decrease power when wind shear happens
If wind changes and come headwind, increase power
in a severe turbulence, what condition do you need to maintain
Level flight attitude with recommended power setting.
Don’t turn back
Timing for airmet
Max period is 6 hours
What info. Airborne weather avoidance radar show?
Location of particles in the atmoshpehre and precipitation size.
Airborne weather avoidance radar show: can it show location of cloud size, ceilings or restrictions to visibility?
NO
Winter+tem is below freezing and autopilot during climb. concern is:
Increase AOA and vulnerable to icing further aft. Slower speed is more chance of icing.
How to report Icing to ATC?
1) Trace 2) light 3) Moderate 4) Severe
High level significant weather prognostic chart
Yellow line
360/XXX
HAT symbol
Moderate or greater turbulence
Layer of turbulence between FL24 to 360
Moderate turbulence
Wind Barbs symbols mean one short barb one long barb flag Calm
5knots
10knots
50knots
Metar VV008
Sky obscured with a vertical visibility go 800ft
Headwing and wind shear to tail. Your next step
Increase power a little
First step of planning an instrument cross country actual IFR
Get the big picture
look at surface analysis
weather deposition charts, significant weather prognostic charts
look for high, low level pressure area fronts, dew/ temperature, wind directions, local information
Area the TAF established.
5SM miles of a local area
Which level of clouds more susceptible to icing
low level
What do you need to do with Icing and autopilot
hand-fly the plane and easier to feel if icing is happening
METAR RAESNB42
Rain ended and snow begun 42 mins past the hour
Moderate icing and winds of 30 knots: segment or airmet?
airmet
Difference between Convective segment and non convective segment
Convective segment: Embedded thunderstorms
NonConvective segment: Severe turbalnce, icing, volcano ash.
During a descent, icing is happening, mean above:
chance of warmer air
How doest frost form?
Temp. of collecting surfaces is below dew point of surrounding air and the dew point is older then freezing
Plane encounter heading of 45 know. expect tola of winshear
90knots
thunderstorm avoidance
stay 20NM
Timeframe of convective outlook:
Day 1 : Five times per day
Day 2:Twice a day
Day 3:once in a day
P6SM. P means:
