Wind shear warning.
Cqb15 july 2011.
Question 182-20 : What is determined by a transmissometer ?
Visibility, runway visual range.
Question 182-21 : Which of the following constant pressure charts would be most relevant for planning a flight at fl330 ?
250 hpa.
Cqb15 july 2011....there is a few questions at the exam that take information directly from that table below, write these down on a sticky and have them on the wall beside you..1013 hpa = msl..850 hpa = fl50..700 hpa = fl100..500 hpa = fl180..300 hpa = fl300..200 hpa = fl390....any others you can interpolate between these and figure it out...the decrease of 1hpa/27ft is only applicable at the lower levels of the troposphere, as you go up and air pressure decreases, the change of height per 1 hpa increases at msl 1hpa/27ft, at fl180 it's 50ft/hpa and at fl390 it's 105ft/hpa.
Question 182-22 : A cold air pool can be best identified by means of ?
The isohypses on an upper air chart.
.isohypses contour lines are drawn on a constant pressure chart, therefore they indicate the true altitude of a pressure level. on an upper air chart, as it includes temperature and wind indications, you can easily identify a cold air pool you will have an area with light or no wind, low temperature.
Question 182-23 : What wind direction will occur over the sea at point 'f' . 374 ?
South.
.we know that the wind blows parallel to the isobars, we can see a warm front c , a cold front a , a warm sector b and a cold occlusion d..note it's a cold occlusion since the line of the occlusion is approximately along the same line as the cold front...with the cold occlusion and the warm sector, it's a depression located in the northern hemisphere. over the sea, angle between wind direction and isobars changes by 10° value to be used in examinations..we can assume that the wind direction at point 'f' is south.
Question 182-24 : What are the normal and official sources of meteorological information for an aircraft in flight ?
Volmet broadcast, atis, all ats units.
Cqb15 august 2011.
Question 182-25 : Runway visual range is calculated from values derived from ?
Transmissometers.
.the meteorological measurement of runway visual range is performed by transmissometers or forward scatter meters placed on the airport.
Question 182-26 : What is an 'aerodrome warning' ?
A message issued by a meteorological office concerning the meteorological conditions which could adversely affect aircraft on ground, including parked aircraft, and the aerodrome facilities and services.
Question 182-27 : An aerodrome warning message gives information, among other things, about ?
Ts, sn including the expected or observed snow accumulation, hoar frost.
Question 182-28 : What are the colours with which a stationary front is shown on a surface chart ?
Red and blue.
. 488.cold front blue..warm front red.
Question 182-29 : How would the term 'vertical visibility is missing or not measurable' be indicated in a metar ?
Vv///.
Question 182-30 : An aircraft is flying from point a to point b at the flight level corresponding to the pressure surface of the constant pressure chart. which of the following statements is correct.. 379 ?
Wind speed over a is higher than over b.
The wind arrow at melbourne indicates that the system centred above a is a low depression. if you count the contours a is at a lower contour height and, therefore, true altitude than b which is at a lower contour height than melbourne. however, the contours are closer and the wind stronger at a than at b.
Question 182-31 : Which kind of meteorological messages are normally transmitted in a vhf volmet broadcast within europe ?
Metar / speci.
Question 182-32 : While using the airborne weather radar in order to circumnavigate thunderstorms, the radar scope is clear between heavy echoes...which of the following interpretations of the scope is correct ?
The clear area indicates an area from which no echoes are received. however, this radar scope provides no assurance of being in vmc while flying in this area.
Question 182-33 : Which constant pressure chart is standard for fl 240 ?
400 hpa.
Question 182-34 : If a flight at fl 150 is planned, which of these upper wind and temperature charts would be nearest to that flight level ?
600 hpa.
Question 182-35 : For the planning of a flight with an estimated time of departure 0930 local time from an european airport a satellite picture is used to locate areas of fog..what type of satellite imagery available with observation time close to etd does provide most likely the best information to locate these ?
Visual vis and infrared ir , polar orbiting system.
.polar orbiting satellites orbit the earth at an altitude of approximately 850 km. since they complete one orbit every 105 minutes, the satellites circle the earth 14 times a day. because of the orbital shift resulting from the planet's rotation, they move west by approximately 2 time zones per orbit...visual this is basically a photo of the clouds and is only available during daylight hours...infra red measures the heat thermal footprint of areas of cloud or the earth's surface if clouds are thin or absent, and can be used both day and night...geostationary satellites orbit the earth at about 36000 km of altitude.over the equator. they are called geostationary because their position does not change with respect to a point on the surface of the earth..polar orbiting satellites are close to the surface, they provide the best information to locate a small area of fog.
Question 182-36 : Which constant pressure chart is standard for fl 140 ?
600 hpa.
Question 182-37 : Which of the following constant pressure charts would be most relevant for planning a flight at fl 260 ?
400 hpa.
Question 182-38 : Runway visual range is calculated from values derived from ?
Forward scatter meters.
.the meteorological measurement of runway visual range is performed by transmissometers or forward scatter meters placed on the airport.
Question 182-39 : Which of the following messages should be cancelled when the conditions are no longer occurring or no longer expected to occur ?
Aerodrome warning.
Question 182-40 : Which of the following symbols represents a quasi stationary front.. 383 ?
Symbol 3.
