VERIFIED ANSWERS) |AGRADE

What is a stationary front? - ANSWER- A stationary front is when an

advancing warm airmass and an advancing cold airmass converge and

one is not strong enough to overtake the other so the air masses become

stationary.

What is an Isobar? - ANSWER- An Isobar is a line of equal pressure

reduced to sea level. Since pressure varies with altitude, we cannot

readily compare station pressures between stations at different altitudes.

To make them compatible with each other, we must adjust them to a

common level (MSL)

What is standard sea level pressure in

-millibars

-inches of mercury

-millimeters of mercury

-PSI - ANSWER- 1013.2 -millibars

29.92 -inches of mercury

14.7-PSI

760 -millimeters of mercury

Where to find approved WX sources? - ANSWER- Ops specs.

What is a strong pressure gradient (closely spaced isobars) indicate? -

ANSWER- High winds

What is Pressure Altitude? - ANSWER- For pressure altitude, set the

window in your altimeter to 29.92. Whatever value it reads is pressure

altitude.

What is Density Altitude? - ANSWER- pressure altitude corrected for

non-standard temperature.

What is true altitude? - ANSWER- This is the height above "mean sea

level"

What is absolute altitude? - ANSWER- Absolute altitude is your height

above the ground.

Describe circulations associated with high pressure systems. -

ANSWER- High pressure = clockwise circulations

(Anti-cyclones)

Describe circulations associated with low pressure systems. - ANSWERLow pressure = counter-clockwise circulations

(Cyclones)

How often are SIGMETs and AIRMETs issued? - ANSWERAIRMETs:

Scheduled - every 6 hours starting at 0145Z

Max Forecast period - 6 hours

SIGMETs:

Unscheduled - as needed

Max Forecast period - 4 hours

Once issued, how long are SIGMETs good for? - ANSWER- 4 hours

How often are convective SIGMETs issued?

What are the locations?

How long are they good for? - ANSWER- Convective SIGMETs issued

every hour. If there are none, it will say none.

Locations: Western Central East.

Valid for 2 hours.

What is a WX depiction chart?

How often are WX depiction charts issued?

What times are they issued? - ANSWER- Lets you know IFR and VFR

conditions.

WX depiction are issued 8 times a day every 3 hours

starting at 0100z.

How often are Radar summery charts issued? - ANSWER- Radar

summary charts are issued every hour.

Are AIRMETs scheduled? How long are they good for? - ANSWERAIRMETS ARE scheduled 255, 855, 1455, 2055. They are good for 6

hours.

What are SIGMETs? - ANSWER- A SIGMET is issued to alert pilots of

potential hazardous WX not adequately issued in an area forecast.

- Severe and extreme turbulence

- Severe icing

- Widespread dust storms, sandstorms, or VA lowering visibility to

below 3 miles.

What are AIRMETs? - ANSWER- An AIRMET is issued to alert pilots

of potential hazardous WX not adequately issued in an area forecast.

-Moderate icing

-Moderate turbulence

-Sustained winds of 30+knots at the surface

-Widespread areas of ceilings less than 1,000 feet or visibilities of less

than 3 miles.

- Extensive mountain obscurement.

What are convective SIGMETs? - ANSWER- A Convective SIGMET is

issued to alert pilots of potential hazardous WX not adequately issued in

an area forecast.

- Tornadoes

- Lines of T-storms

- Embedded thunderstorms

- T-storms areas greater or equal to intensity level 4

- Hail greater than 3/4 of an inch in diameter

What is an area forecast? (FA) - ANSWER- Expected VMC, clouds, and

general WX conditions over an area the size of several states. FA's

should be used in conjunction with AIRMETs SIGMETs, and

convective SIGMETs to get a full picture.

What locations are SIGMETs issued for? - ANSWER- SFO - San

Francisco

SLC - Salt Lake City

DFW - Dallas Fort Worth

MIA - Miami

CHI - Chicago

BOS - Boston

What are the three types of AIRMETs? - ANSWER- Airmet Sierra (S) -

(Mountain obscuration or IFR) ceilings less than 1000 feet and/or

visibility less than 3 miles affecting over 50% of the area at one time;

extensive mountain obscuration

Airmet Tango (T) - (Turbulence) - Light - moderate turbulence,

sustained surface winds of 30 knots or more.

Airmet Zulu (Z) - (Icing) Light - moderate icing, freezing levels

What is the main difference between a SIGMET and an AIRMET? -

ANSWER- SIGMETs should be considered as significant SEVERE
