Warning airspace areas contain:

Activity that may be hazardous to non-participating aircraft. Warning areas extend from 3NM outwards from the US coast. A warning area may be located over domestic air or international waters or both.

ARROW

Airworthiness certificate, registration certificate, radio station license, operating limitations, weight and balance data

Pitot static system

Altimeter, vertical speed indicator, airspeed indicator (ram air)

Mode C requirements

At or above 10000 MSL except in that airspace below 2500 AGL; within 30NM of class B; within and above a class C; into within or across the U.S. ADIZ

METAR

Aviation routine weather report

Alcohol

Below .04 and no alcohol within 8 hours.

Military training routes are established:

Below 10000MSL for operations at speeds in excess of 250KT. IR means the routes are made in accordance with IFR. VR means VFR. MTRs with one or more segments above 1500AGL have 3 digit numbers and MTRs with no segments above 1500AGL are identified by a four digit number.

Class E airspace shading marks the lower limit of the airspace

The surface in areas marked by dashed magenta lines, 700 ft AGL in areas marked by shaded magenta lines, 1200 AGL in areas marked by shaded blue lines, 1200 AGL in areas defined as Federal Airways. If not defined, the floor of Class E begins at 14,500 MSL or 1200 AGL - whichever is higher

Convective SIGMETs include:

Tornadoes, Lines of thunderstorms, Embedded thunderstorms, thunderstorm areas greater than or equal to thunderstorm intensity level 4 with an area coverage of 40% or more, hail greater than or equal to 3/4in diameter

Steady precipitation preceding a front

Usually an indication of a warm front, which results from warm air being cooked from the bottom by colder air

Density Altitude

Varies directly with temperature and humidity, and varies inversely with barometric pressure

Normal Ground Attitude

Wings Level, 2" of Strut

Military operations areas (MOAs) denote:

areas of military training activities

VOR is depicted as a:

hexagon with a dot in the center

VORTAC is depicted as a:

Yellow arc

Caution range

Federal airways

Class E airspace extending upwards from 1200 AGL to and including 17999 MSL. Within parallel boundary lines 4NM on each side of the airway centerline

Weather reporting station circle

Clear/open, overcast/solid, scattered/ 1/4 solid, broken/ 3/4 solid, obscured/X

Unstable air characteristics

Cumuliform clouds, turbulent air, good visibility, showery precipitation

Lapse rate

Decrease in temperature with increase in altitude

How are lines of longitude and latitude divided?

Each degree subdivided into 60 equal segments called minutes; i.e. 1/2 degree is 30'

Night

End of evening civil twilight and the beginning of morning civil twilight

Restricted airspace areas denote:

Existence of unusual, often invisible hazards to aircraft such as military firing, aerial gunnery, or guided missiles

Mountain wave turbulence

Expect mountain wave turbulence when the air is stable and winds of 40KT or greater blow across a mountain or ridge

Winds aloft greater than 100KT are calculated how?

Forecaster adds 50 to direction and subtract 100 from the speed. Example: 730649 73-50=230 at 06+100=106 at -49 degrees celsius

Thunderstorms

Form when there is: sufficient water vapor, an unstable lapse rate, an initial upward boost to start the process

Advection fog

Forms as a result of moist air condensing as it moves over a cooler surface

Requesting telephone weather briefing

Identify: yourself as a pilot, your intended route, your intended destination, whether VFR or IFR, type of aircraft, proposed departure time and time en route

Class E weather minimums

Less than 10000 MSL, 3SM, 500 ft below/1000 ft above/2000 ft from; at or above 10000 MSL, 5SM, 1000 ft below/1000 ft above/1SM from

Cumulonimbus clouds

Lifting action, unstable air, and moisture are the ingredients for formation

Va

Maneuvering speed (maximum speed for flight in turbulent air)

Vfe

Maximum full flaps extended speed

Vno

Maximum structural cruising speed for normal operation

Lenticular clouds

May contain winds of 50KT or more

AIRMETs apply to light aircraft to notify of:

Moderate icing, moderate turbulence, visibility less than 3SM or ceilings less than 1000FT, sustained winds of 30KT or more at the surface, extensive mountain obscurement

Radiation fog

Most likely to occur when there is a clear sky, little or no wind, and a small temperature/dew point spread

Requires: flight through visible moisture, and the temperature at freezing or below

Upslope fog

Results from warm, moist air being cooked as it is forced up sloping terrain

SIGMETs include:

Severe or extreme turbulence or clear air turbulence (CAT) not associated with thunderstorms, severe icing not associated with thunderstorms, duststorms, sandstorms, or volcanic ash lowering visibility to less than 3SM, volcanic eruption

Stable air characteristics

Abbreviated briefing

Supplement mass disseminated data, update a previous briefing, or be limited to specific information

Temperature inversion

Temperature increases as altitude increases, usually resulting in a layer of stable air
