1 THE TWO MAIN CONSTITUENT GASES IN THE LOWER ATMOSPHERE IS 2 THE TYPE OF WEATHER THAT WOULD BE EXPECTED ABOVE A 'SQUALL LINE' WOULD BE : 3 RADIATION FOG MAY BE FOUND WITH A WIND VELOCITY OF 4 THE MOST SEVERE ICING TAKES PLACE OVER MOUNTAINS 5 FLYING AT 5,000 FT AND LOWERING STRATUS CLOUDS WERE COMING, WHAT TYPE OF WEATHER WOULD YOU EXPECT 6 MAXIMUM ICING CONDITIONS OCCUR 7 HAIL IS USUALLY FOUND IN WHAT TYPE OF CLOUD 8 WHICH FRONT IS STEEPER 9 IN CUMULONIMBUS CLOUDS WHERE HAIL IS BEING FORMED, THE VERTICAL CURRENTS MAY BE EXPECTED TO BE 10 HOW HIGH DOES A 'SQUALL LINE' EXTEND 11 ICE SELDOM FORMS ON A PLANE WITH THE TEMPERATURE ZERO BECAUSE 12 IF A PILOT WERE FLYING THROUGH A WARM FRONT FROM THE WARM AIR SIDE TO THE COLD AIR SIDE AND FLYING AT 5,000 FT. HE WOULD EXPECT TO FIND HIS WIND SHIFT

13 IF THE PILOT IS FLYING FROM AN AIRPORT WHERE THE PRESSURE IS HIGH TO ANOTHER AIRPORT WHERE THE PRESSURE IS MUCH LOWER AND LEAVES HIS ALTIMETER SET TO THE ALTIMETER SETTING OF HIS DEPARTURE AIRPORT, ON HIS ARRIVAL AT HIS DESTINATION HE WOULD FIND HIS ALTIMETER WOULD READ 14 IF A CERTAIN STATION SHOULD REPORT A SURFACE TEMPERATURE OF 46 DEGREES F. A PILOT WOULD NORMALLY EXPECT TO FIND ICING CONDITIONS AT AN ALTITUDE APPROXIMATELY 15 IN THE SUMMER WARM TROPICAL AIR FROM THE TROPICAL ATLANTIC MOVES IN THE OVER THE COAST WHERE THE TEMPERATURE IS MUCH HIGHER. THE MOST PROBABLE RESULT WOULD BE 16 A FOG FORMED BY WARM, MOIST AIR FLOWING OVER A COLDER SURFACE IS CALLED 17 BUYS BALLOTS LAW STATES THAT IN THE NORTHERN HEMISPHERE, IF A PERSON STANDS WITH HIS BACK TO THE WIND, THE AREA OF LOWER PRESSURE WILL BE 18 IF A PILOT SET HIS ALTIMETER TO READ ZERO IN THE EVENING WHEN HE LEFT HIS AIRPLANE, AND IN THE MORNING IT READ 500 FT., THE BAROMETRIC PRESSURE WOULD BE 19 IN THE NORTHERN HEMISPHERE AT ALTITUDES OF 2,000 FT. OR 3,000 FT. THE AIRFLOW'S GENERALLY 20 IF YOU ARE FLYING AT AN INDICATED ALTITUDE OF 1000 FEET AND THE OUTSIDE AIR TEMPERATURE IS 10 DEGREES C YOUR TRUE ALTITUDE WOULD BE

21 IF YOU ARE FLYING INTO AN AREA MARKED ON THE WEATHER MAP AS 'LOW' AND HOLDING A CONSTANT INDICATED ALTITUDE YOUR ACTUAL ALTITUDE WOULD BE 22 IN APPROACHING A RAPIDLY MOVING COLD FROM A PILOT WOULD EXPECT TO FIND, (AT A POINT ABOUT) 200 MILES IN ADVANCE OF THE FRONT 23 ON THE LEE SIDE OF MOUNTAINS AND BUILDINGS, YOU WOULD NORMALLY EXPECT TO FIND 24 THUNDERSTORMS CAN EXPECTED TO DEVELOP AS A RESULT MAINLY FROM WHICH OF THE FOLLOWING TYPES OF CLOUDS 25 IF YOU HAVE TO FLY THROUGH AN OCCLUSION RUNNING NORTH-SOUTH, YOU SHOULD, IN RELATION TO THE WARM SECTOR OF THE OCCLUSION, FLY TO THE 26 THE CLOUDS WHICH ARE MAINLY CHARACTERISTICS OF A WARM FRONT ARE KNOWN AS 27 THE TYPE OF CLOUDS WHICH A PILOT WOULD EXPECT TO FIND IN A CPK AIRMASS ARE 28 THE WORD 'FRONTOLYSIS' PRINTED ON A WEATHER MAP MEANS 29 IF YOU WERE FLYING IN AN AREA ABOUT 50 MILES IN ADVANCE OF A TYPICAL WARM FRONT, THE TYPE OF CLOUDS WHICH YOU WOULD EXPECT TO ENCOUNTER WOULD BE 30 ON A CLEAR, CALM NIGHT YOU MAY EXPECT WHICH OF THE FOLLOWING FOGS 31 TYPICAL WEATHER ASSOCIATED WITH A WARM FRONT WOULD BE CHARACTERISED BY

32 A CERTAIN STATION REPORTS A SURFACE TEMPERATURE OF 44 DEGREES F AND A SURFACE DEW POINT OF 35 DEGREES F. A STEADY DRIZZLE IS FALLING AT THE STATION. A PILOT FLYING OVER THE STATION WOULD EXPECT TO ENCOUNTER ICING CONDITIONS AT AN ALTITUDE OF APPROXIMATELY 33 A PILOT LEAVES FROM AN AIRPORT (ELEVATIONS 4,500 FT.) BROADCASTING AN ALTIMETER SETTING OF 29.70 WITH HIS ALTIMETER READING 4,500 FT. HE FLIES TO AND LANDS AT A SEA LEVEL AIRPORT BROADCASTING IN ALTIMETER SETTING OF 30.20 WITHOUT SETTING HIS ALTIMETER. HIS ALTIMETER READING UPON LANDING AT THE SEA LEVEL AIRPORT WOULD BE 34 A STATION REPORTS TEMPERATURE 80 DEGREES F., CEILINGS 5,000 FT. WITH TOPS OF CLOUDS AT 15,000 FT. A FREEZING TEMPERATURE CAN BE EXPECTED AT ABOUT 35 IF THE WIND ABOVE A CERTAIN STATION IS REPORTED TO BE FROM THE NORTH AT AN ALTITUDE OF ABOUT 3,000 FT. YOU WOULD NORMALLY EXPECT THE SURFACE WIND TO BE FROM 36 DURING A CROSS-COUNTRY FLIGHT, YOU FIND THAT THE CEILINGS ARE CONSIDERABLY LOWER THAN WERE FORECAST. IN MAKING A RADIO REPORT TO THE WEATHER BUREAU, YOU WOULD REPORT THE HEIGHT OF THE CLOUDS

37 IF YOU WERE FLYING IN A WESTERLY DIRECTION AND ENCOUNTERED THE FOLLOWING SEQUENCE OF CLOUD FORMATIONS CI,CS. AS YOU WOULD KNOW THAT 38 YOU ARE FLYING A CONSTANT HEADING AND OBSERVE A SEQUENCE OF CIRRUS, CIRRO-STRATUS AND ALTOSTRATUS CLOUDS. THIS WOULD INDICATE 39 THE PRESSURE OF HAIL IN A CLOUDY ALWAYS INDICATES 40 IF A LIGHT STEADY RAIN IS FALLING AND THE GROUND TEMPERATURE IS 50 DEGREES F., THE ICING WILL BE MOST NEARLY 41 AN AIRPLANE SHOULD LAND AT A HIGHER THAN NORMAL SPEED WHEN 42 A PILOT IS ENROUTE ON AN INSTRUMENT FLIGHT. ATC REQUESTS THAT HE MAKE A REPORT OF CURRENT WEATHER CONDITIONS IN HIS VICINITY. IN SO DOING THE PILOT SHOULD REPORT THE BASE OF THE CLOUDS 43 YOU ARE PLANNING A FLIGHT IN THE VICINITY OF COLD FRONT IN CHECKING THE WEATHER MAP CAREFULLY YOU NOTE THE WORD 'FRONTOGENISIS' IN CLOSE PROXIMITY TO THE HEAVY LINE REPRESENTING THE FRONT ON THE MAP. THUS SHOULD INDICATE TO YOU THAT

44 ON A RECENT INSTRUMENT FLIGHT A PILOT NOTED THAT EACH STATION ON HIS ROUTE REPORTED A LOWER PRESSURE THAN THE PRECEDING STATION. HE SHOULD KNOW THAT IF HE DOES NOT KEEP HIS ALTIMETER CORRECTED HIS ACTUAL ALTITUDE WILL BE 45 PRIOR TO AN INSTRUMENT FLIGHT A PILOT STUDIES THE CURRENT WEATHER MAP AND NOTES THAT ON HIS PROPOSED ROUTE THERE ARE TWO AIR MASS SYMBOLS, ONE ABOVE THE OTHER AND SEPARATED BY A STRAIGHT LINE. HE CONCLUDES THAT 46 A PILOT ON AN INSTRUMENT FLIGHT REQUESTS A WEATHER REPORT. HE IS GIVEN THE REPORT, AND IN ADDITION IS ADVISED THAT A SQUALL LINE LIES IN THE PATH OF HIS FLIGHT. HE WOULD BE JUSTIFIED IN ASSUMING THAT THE AREA OF A SQUALL LINE WILL 47 THUNDERSTORM ACTIVITY ON THE WINDWARD SIDE OF MOUNTAIN RANGES IN CAUSE BY 48 A THUNDERSTORM IS CONSIDERED TO BE IN PROGRESS AT THE STATION OF OBSERVATIONS WHEN 49 AN INSTRUMENT PILOT IS INFORMED THAT THERE MAY BE LOW CLOUDS OF BAD WEATHER ON HIS PROPOSED FLIGHT.
