1Which of the following describes the standard sea level temperature and pressure according to the International Standard Atmosphere (ISA)?

A.15°C and 29.92 inches of mercury (1013.25 hPa)

B.0°C and 1013.25 hectopascals (29.92 inches of mercury)

C.15°C and 1013.25 inches of mercury (29.92 hPa)

D.20°C and 29.92 millibars (1013.25 hPa)

Explanation: According to the International Standard Atmosphere (ISA), standard sea level conditions are defined as a temperature of 15°C (59°F) and a barometric pressure of 29.92 inches of mercury (in. Hg) or 1013.25 hectopascals/millibars (hPa/mb). These standard baseline values are essential for altimetry and aircraft performance calculations.

2What is the primary characteristic that defines the boundary of the tropopause?

A.An abrupt increase in water vapor concentration

B.An abrupt change in the temperature lapse rate, where it drops to near 0°C per 1,000 ft

C.A sudden reversal of wind direction from westerly to easterly

D.The level at which atmospheric pressure drops to exactly 500 hPa

Explanation: The tropopause is the boundary layer separating the troposphere from the stratosphere. It is defined by an abrupt change in the temperature lapse rate, where the average tropospheric decrease of 1.98°C/1,000 ft drops to 0°C/1,000 ft or becomes positive (an inversion) in the stratosphere.

3What is the standard temperature lapse rate in the troposphere under ISA conditions?

A.1.5°C per 1,000 feet of altitude gain

B.1.98°C per 1,000 feet of altitude gain

C.3.0°C per 1,000 feet of altitude gain

D.0.5°C per 1,000 feet of altitude gain

Explanation: Under the International Standard Atmosphere (ISA), the temperature in the troposphere decreases at a standard lapse rate of 1.98°C per 1,000 feet (often rounded to 2.0°C/1,000 ft) up to the tropopause (36,090 feet ASL), above which it becomes isothermal.

4How does the height of the tropopause typically vary with latitude and season?

A.It is highest over the poles in winter and lowest over the equator in summer

B.It is highest over the equator and lowest over the poles, and is lower in winter than in summer

C.It maintains a constant height of 36,000 feet across all latitudes and seasons

D.It is lowest over the equator and highest over the poles, and is higher in winter than in summer

Explanation: The height of the tropopause varies with latitude and season due to temperature differences. Cold air is denser and compresses the troposphere, leading to a lower tropopause over the poles (down to 25,000 ft) and in winter. Warm air expands the troposphere, raising the tropopause over the equator (up to 55,000 ft) and during the summer.

5Which physical process is the primary mechanism by which the troposphere is heated?

A.Direct absorption of shortwave solar radiation by nitrogen and oxygen gases

B.Absorption of longwave terrestrial radiation emitted by the Earth's surface

C.Frictional heating caused by surface winds blowing across terrain

D.Latent heat released during the deposition of frost at high altitudes

Explanation: The atmosphere is largely transparent to shortwave solar radiation, which passes through it and heats the Earth's surface. The surface then re-radiates this energy as longwave (infrared) terrestrial radiation, which is absorbed by greenhouse gases (water vapor, CO2) in the troposphere. Therefore, the troposphere is heated from below.

6Why does the temperature in the stratosphere increase with an increase in altitude?

A.Due to the increasing concentration of carbon dioxide trapping heat from space

B.Due to the absorption of ultraviolet (UV) solar radiation by ozone molecules

C.Due to compressional heating as air sinks from higher atmospheric layers

D.Due to intense friction from high-speed meteorites entering the atmosphere

Explanation: The stratosphere contains the ozone layer (maximum concentration around 20-30 km). Ozone molecules absorb harmful ultraviolet (UV) radiation from the sun, which raises the kinetic energy of the molecules and heats the surrounding air, causing the temperature inversion characteristic of the stratosphere.

7Calculate the approximate density altitude for an airport with a pressure altitude of 4,000 feet and an outside air temperature (OAT) of 23°C.

A.4,960 feet

B.5,920 feet

C.3,040 feet

D.4,000 feet

Explanation: Using the standard formula: Density Altitude = Pressure Altitude + [120 x (OAT - ISA Temp)]. 1) ISA temperature at 4,000 feet = 15°C - (2°C x 4) = 7°C. 2) OAT deviation = 23°C - 7°C = +16°C. 3) Density Altitude = 4,000 + (120 x 16) = 4,000 + 1,920 = 5,920 feet.

8What is the difference between station pressure and sea level pressure?

A.Station pressure is corrected for temperature, while sea level pressure is corrected for gravity

B.Station pressure is the actual barometric pressure measured at the station's elevation, while sea level pressure is station pressure adjusted to sea level using a standard temperature column

C.Station pressure is measured in hectopascals, while sea level pressure is measured exclusively in inches of mercury

D.There is no difference; they are synonymous terms for atmospheric pressure

Explanation: Station pressure is the raw barometric pressure at the elevation of the weather station. Sea level pressure (SLP) is calculated by adding a theoretical column of air from the station's elevation down to sea level, adjusted for the current station temperature, allowing meteorologists to plot comparable values on surface charts.

9Which of the following describes a temperature inversion?

A.A layer of the atmosphere where temperature decreases faster than the dry adiabatic lapse rate

B.A layer where temperature increases with an increase in altitude

C.A condition where surface temperatures are exactly 0°C

D.An atmospheric layer where the dewpoint matches the air temperature

Explanation: A temperature inversion is an atmospheric condition where temperature increases with height, reversing the normal tropospheric cooling trend. Inversions act as 'lids' on the atmosphere, trapping moisture, pollutants, and causing smooth but hazy conditions with potential wind shear at the boundaries.

10What is the definition of pressure altitude?

A.The altitude read on the altimeter when it is set to the local altimeter setting (QNH)

B.The altitude of the aircraft above the ground (AGL)

C.The altitude indicated when the altimeter's barometric scale is set to standard sea level pressure of 29.92 inches of mercury (1013.2 hPa)

D.The true altitude corrected for non-standard temperature variations

Explanation: Pressure altitude is the height above the standard datum plane (29.92 in. Hg / 1013.2 hPa). Setting the altimeter's barometric scale to 29.92 references the instrument to standard pressure, which is critical for aircraft performance calculations and high-altitude flight level operations.

About the Transport Canada Flight Dispatcher Meteorology Exam Exam

The Transport Canada Flight Dispatcher Meteorology Generic Examination (FDMET) is one of two exams required to obtain a Flight Dispatcher Licence in Canada (the other being FDOPS). This highly technical exam tests a candidate's deep understanding of weather theory, thermal structures, atmospheric pressure and winds, atmospheric moisture, air masses, frontal weather (including trowals), aircraft icing, turbulence types, thunderstorms, wind shear, and weather hazards. It also requires advanced proficiency in decoding and interpreting aviation weather reports, forecasts, and maps such as METARs, SPECI, TAFs, Graphic Area Forecasts (GFAs), Upper Winds (FD), SIGMETs, and surface analysis charts.

Assessment

The FDMET exam consists of 100 multiple-choice questions written at an authorized Transport Canada location. Candidates must answer at least 70 questions correctly to pass. The exam is structured around weather theory, pressure/winds, moisture/clouds, fronts, icing/turbulence, thunderstorms, and reports/forecasts.

Transport Canada Flight Dispatcher Meteorology Exam Study Tips from Top Performers

1Familiarize yourself with Canadian-specific products. Transport Canada exams emphasize Graphical Area Forecasts (GFAs) and the Trowal (Trough of Warm Air Aloft), which are not typically found in US FAA exams.

2Practice wind decoding above 100 knots in FD forecasts (e.g., subtracting 50 from direction and adding 100 to speed). This is a common source of errors.

3Understand the mechanics of altimetry errors: remember 'from high to low, look out below' and 'from hot to cold, look out below' to identify indicated vs. true altitude errors.

4Drill the temperature ranges for different icing types: clear ice is most common between 0°C and -10°C, mixed ice between -10°C and -15°C, and rime ice between -15°C and -20°C (or colder).

5Be able to identify the exact stage of a thunderstorm: mature stage is defined by the beginning of precipitation at the surface and the coexistence of updrafts and downdrafts.
