Q

if the isobars are relatively close together on a Surface weather chart or a constant pressure chart what information will this provide

A

Closely spaced isobarsindicate large pressure changes over a small area and suggest strengtheningwinds.Widely spaced isobarsportray a “flat” or weak pressure gradient typical of light-windsituations.

Q

Name the three types of structural icing that may occur in flight

A

Clear ice -forms after initial impact with the remaining liquid portion of the drop flows over the aircraft surface, gradually freezing as a smooth sheet of solid ice.

Rime ice - forms when crops are small, such as those in stratified clouds or light drizzle. The liquid portion remaining after initial impact freezes rapidly before the drop has time to spread out over the aircraft system.

Mixed ice- forms when Trump’s vary in size or when liquid drops are intermingled with snow or ice particles. The ice particles become embedded in clear ice, building a very rough accumulation.

Q

What action is recommended if you inadvertently encounter icing conditions?

A

Leave the area of visible moisture descend to an altitude below the cloud bases, climb to an altitude above the cloud tops, or turn to a different course.

Q

Is Frost considered to be hazardous to flight? Why?

A

Yes because well Frost does not change the basic aerodynamic shape of the wing, the roughness of its surface spoils the smooth flow of air, thus causing a slowing of airflow. This slowing of the air causes early air flow separation, resulting in a loss of lift. Even a small amount of frost on airfoil May prevent an aircraft from becoming airborne at normal takeoff speed. It is also possible that, once airborne, an aircraft could have insufficient margin of AirSpeed above stall so that the moderate gusts of turning flight could produce incipient or complete stalling.

Q

What are the three stages of a thunderstorm

A

Cumulus stage of updrafts cause raindrops increase in size

Mature stage rain at Earth’s surface, it falls through or immediately besides the updrafts, lightning, perhaps roll clouds

Dissipating stage downdrafts and rain began to dissipate

Q

What is a temperature inversion

A

An inversion is an increase in temperature with height a reversal of the normal decrease with height. A ground-based inversion favors poor visibility by trapping fog, smoke, and other restrictions in to low levels of the atmosphere. The air is stable, with little or no turbulence.

Q

Name several types of fog.

A 
Radiation fog 
 Advection fog 
Upslope fog 
 Frontal fog or precipitation induced fog 
 Steam fog
21
Q

What causes radiation fog to form

A

The ground cools the adjacent are to the dew point on calm, clear nights.

22
Q

What is advection fog, and where is it most likely to form?

A

Advection fog results from the transport of warm humid air over a cold surface. A pilot can expect advection fog to form primarily along coastal areas during the winter. Unlike radiation fog, it’s may occur with winds, cloudy skies, over a wide geographic area, and at any time of the day or night.

23
Q

What is upslope fog?

A

Upslope fog forms as a result of moisture, stable are being cooled adiabatically as it moves up sloping terrain. Once the upslope wind ceases, the fog dissipates. Upslope fog is often quite dense and extends to high altitudes.

24
Q

Define the term “wind shear” and state the areas in which it is likely to occur

A

It is defined as a rate of change of wind velocity direction and or speed per unit distance, conventionally expressed as vertical or horizontal wind shear it may occur at any level in the atmosphere but three areas are of special concern:
Windshear with a low-level temperature inversion
Windshear in a frontal zone or thunderstorm
Clear-air turbulence at high levels associated with a jet stream or strong circulation.

25
Q

What types of weather information will you examine to determine if windshield conditions might affect your flight

A

Terminal forecast any mention of low-level wind shear or the possibility of severe thunderstorms rain showers hail and wind gust suggest a potential for low-level wind shear and microburst
METARs inspect for any indication of thunderstorms rain showers or blowing dust additional signs such as warming trends Gusty winds cumulonimbus clouds at said I should be noted
S i g m e t s, and convective sigmet severe convective weather is a prime source for wind shear a microburst
PIREPs reports of sudden AirSpeed changes on departure or approach-and-landing corridors provide a real-time indication of the presence of windshear

26
Q

What is a primary means of obtaining a weather briefing

A

the flight service station is a primary source for obtaining pre-flight briefings and in-flight weather information. The FAA provides the flight service program through FSS both government and contract via the internet through direct user access terminal system and the Lockheed Martin Flight services.

27
Q

What types of weather briefings are available from an AFSS / FSS briefer?

A

Standard briefing
Abbreviated briefing
Outlook briefing
In Flight briefing

28
Q

What is a standard briefing

A

request when you are pregnant if you have not received the previously been or have been receiving information dissemination media.

29
Q

What is an abbreviated briefing

A

Requested when you need information to supplement Mass disseminated data, update a previous briefing, or when you need only one or two items.

30
Q

What is an Outlook briefing

A

Request whenever you proposed time of departure is six or more hours from the time of the briefing, for planning purposes only

31
Q

What is a in-flight briefing

A

Request when needed to update a pre-flight briefing

32
Q

What pertinent information should a weather briefing include?

A 
Adverse conditions 
 VFR flight not recommended 
 Synopsis 
 Current conditions 
 In route forecast 
 Destination forecast 
 Winds aloft 
 Notices to airmen 
 ATC delays 
 Pilots may also request additional information such as:
Special use airspace and alert areas such as MOA, MTRs, warning areas, and ATC assigned airspace.
Additional information information on air traffic services and rules, customs and immigration procedures, adiz rules, search and rescue, runway friction measurement value and other assistance as required.
33
Q

What is HIWAS?

A

Hazardous and weather advisory services RCN news broadcast of the weather valley center weather warning signals convective sigmet center weather advisory and urgent PIREPs.

34
Q

What is a flight information service

A

Flight information service broadcast is a ground broadcast service provider through the automatic dependent surveillance the system provides pilots and flight crews of properly equipped aircraft with flight deck display of aviation weather and aeronautical information

35
Q

Can onboard data link weather be useful in navigation in aircraft safely around an area of thunderstorms?

A

Weather data link from a ground weather surveillance radar system is not real time information, it displays recent rather than current conditions. This data is typically updated every 5 minutes but can be as much as 15 minutes old by the time it displays in the cockpit. Therefore FIS aviation weather products are not appropriate for tactical avoidance of severe weather such as negotiating a pass-through weather hazard area.

36
Q

While enroute how can A+ pain up to date weather information

A
