ATPL SAMRA Practice Exam Questions
And All Correct Answers.
Define ISOBAR: - Answer Lines connecting the areas of equal pressure
ISOBAR Standard separation: - Answer 4 millibars apart
ISOBAR Air flow: - Answer From High pressure areas to Low pressure areas
High Pressure Areas: - Answer Descending air
Air rotates Clockwise (North )
Outward from the center
Fair weather
Can remain stationary for days
Low Pressure Areas: - Answer Rising air
Air rotates Counterclockwise ( North )
Inward toward the center
Thunderstorms and unstable weather
Tend to be very quick moving
Troughs: - Answer It is a long area of Low Pressure
Ridges: - Answer It is a long area of High Pressure
Col: - Answer It is a neutral area between two Highs and two Low areas
Altimeter setting is based on: - Answer Sea level
Flying from Different Pressure Areas: - Answer From High to Low - The aircraft will gradually
descent.
,A GFA (Graphical Area Forecast)is valid for: - Answer 12 hours with an additional outlook
period of 12 hours.
GFA (Graphical Area Forecast) Charts: - Answer -Are issued 4 times daily
-Approximately 30 min before the beginning of
the forecast period
-They are valid at: 0000, 0600, 1200, 1800
A GPS system requires how many satellites to provide a 3 dimensional position? - Answer 4
satellites
There are 6 types of FOG: - Answer -Radiation
-Advection
-Upslope
-Frontal
-Steam
-Ice
Basic ingredients to form a FOG: - Answer -High Humidity
-Condensation Nuclei
-Very light surface wind
-Cooling process
Radiation Fog - Answer -Formed by radiation cooling on clear nights where the relative
humidity is high and light winds are present.
-Most likely to present shortly after sunrise
Advection Fog - Answer -Formed by the horizontal movement of warm moist air over a colder
surface
-Typically dense and can last for several days
-Winds above 15kt may lift the fog
, -Precipitation from a warm front falls into cold air below. As the rain evaporates, saturation
occurs causing fog
Steam Fog - Answer -Also Known as Artic Sea Smoke
-Forms by water vapour being added to the air
-Ideal conditions are when extreme cold air blows over the ocean
-When the water vapour condenses, a fog or mist will form
Difference between Mist and Fog - Answer Visibility exceeds 5/8 of a mile = Mist (BR)
Visibility below 5/8 of a mile = Fog (FG)
SIGMET (Significant Meteorological Information) - Answer -Severe thunderstorm
-Squall line
-Hail
-Volcanic Ash
-Hurricane
-Tornadoes
-Severe icing
-Mountain waves
-Send or dust storms
-Low-level wind shear
TAF ( Terminal Aerodrome Forecast) - Answer -A TAF gives the weather that is expected within
5 NM of the runway complex.
-Clouds high are in AGL
- Winds are in degrees TRUE
-Issued 4 times a day for either, 12, 24 and 30 hours period
A winter warm front will give what kind of weather? - Answer Freezing rain and ice pellets
ADF airways: - Answer NDB systems are flight checked to an accuracy of at least ±5° for an
approach and ±10° for enroute
