Sample SACAA PPL Meteorology Practice Questions

Try these sample questions to test your SACAA PPL Meteorology exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which two gases make up approximately 99% of the dry atmosphere by volume?

A.Oxygen and carbon dioxide

B.Nitrogen and water vapour

C.Oxygen and ozone

D.Nitrogen and oxygen

Explanation: Dry air is about 78% nitrogen and 21% oxygen. The remaining ~1% includes argon, carbon dioxide, and other trace gases. Water vapour is variable and not counted in dry-air percentages.

2In which atmospheric layer does virtually all weather important to PPL operations occur?

A.Troposphere

B.Stratosphere

C.Mesosphere

D.Thermosphere

Explanation: Weather processes involving vertical motion, clouds, and precipitation occur in the troposphere. Above the tropopause, vertical motion is usually limited and weather as pilots experience it is absent.

3Approximately what is the average height of the tropopause in the ICAO Standard Atmosphere?

A.About 18 000 ft

B.About 10 000 ft

C.About 60 000 ft

D.About 36 090 ft

Explanation: ISA places the tropopause at about 11 km (36 090 ft), where temperature stops falling at −56.5°C. Real tropopause height is lower over the poles and higher over the equator.

4What is the ICAO Standard Atmosphere sea-level temperature?

A.15°C

B.0°C

C.20°C

D.10°C

Explanation: ISA defines mean sea-level temperature as 15°C. This standard is used for aircraft performance comparisons and many altimetry/density calculations.

5What is the ICAO Standard Atmosphere sea-level pressure?

A.950 hPa

B.1013.25 hPa

C.1000.00 hPa

D.29.00 inHg

Explanation: ISA MSL pressure is 1013.25 hectopascals (historically millibars). This is also the standard altimeter setting for flight levels.

6What approximate temperature lapse rate is used in the International Standard Atmosphere in the troposphere?

A.1°C per 1 000 ft

B.3°C per 1 000 ft

C.5°C per 1 000 ft

D.About 2°C per 1 000 ft (1.98°C/1 000 ft)

Explanation: ISA uses 6.5°C/km, which converts to about 1.98°C per 1 000 ft. South African teaching commonly accepts ~2°C/1 000 ft for calculations.

7What is the ISA temperature at the tropopause once the standard lapse has been applied?

A.0°C

B.−40°C

C.−56.5°C

D.−15°C

Explanation: Starting from 15°C at sea level and cooling at 6.5°C/km through 11 km yields −56.5°C, which ISA holds constant through the lower stratosphere.

8Which statement correctly describes air motion in the troposphere compared with the lower stratosphere?

A.The stratosphere contains all precipitation

B.The troposphere has significant vertical and horizontal motion; above the tropopause motion is usually mainly horizontal

C.Both layers have equally strong vertical convection

D.The troposphere has only horizontal motion

Explanation: Weather-producing vertical currents are a hallmark of the troposphere. Above the tropopause, stability usually suppresses large vertical exchanges.

9What is the approximate ISA sea-level air density?

A.1.225 kg/m³

B.1.000 kg/m³

C.12.25 kg/m³

D.0.225 kg/m³

Explanation: ISA defines sea-level density as 1.225 kg/m³ (1 225 g/m³). Density decreases with altitude and with warmer-than-ISA temperatures at a given pressure level.

10A useful memory aid for tropopause height is that high surface temperatures are associated with a:

A.Lower tropopause

B.Thicker mesosphere

C.Fixed tropopause at 18 000 ft

D.Higher tropopause

Explanation: The tropopause is generally higher over warm equatorial regions (~18 km) and lower over cold polar regions (~8 km). High surface temperature correlates with a higher tropopause.

About the SACAA PPL Meteorology Exam

The SACAA PPL Aviation Meteorology examination is a mandatory computer-based theoretical knowledge subject for the South African Private Pilot Licence (Aeroplane). It tests the atmosphere and ISA, pressure/density/temperature, humidity and precipitation, wind systems, clouds and fog, air masses and fronts, icing and thunderstorms, mountain flying weather, Southern African climatology, altimetry, and interpretation of METAR/TAF/SPECI/SIGMET and chart products from the official PPL Meteorology syllabus.

SACAA PPL Meteorology Study Tips from Top Performers

1Memorise ISA sea-level values (15°C, 1013.25 hPa, ~2°C/1000 ft lapse) and the ~30 ft per hPa rule used in SA teaching.

2Drill Southern Hemisphere wind flow: Coriolis deflects left; highs circulate anticlockwise; Buys Ballot places the low on your right with your back to the wind.

3Practise decoding METAR/TAF groups from the SACAA PPL Meteorology Manual examples (SA aerodrome codes, FEW/SCT/BKN/OVC, CAVOK).

4Know radiation vs advection fog triggers, and which clouds imply severe turbulence/icing (especially CB).

5Learn SA local winds: Berg wind, Cape Doctor, Black South Easter, South-Westerly Buster, and summer thermal lows over the interior.

Frequently Asked Questions

What is the pass mark for the SACAA PPL Meteorology exam?

CAR 61.01.10 sets the pass mark for SACAA theoretical knowledge examinations at 75%. There is no negative marking, so unanswered questions should still be attempted before time expires.

How many questions and how much time does SACAA PPL Meteorology allow?

Meteorology is commonly scheduled for about 60 minutes. Question counts are typically in the 20–40 range (often around 30) depending on the paper generated by the SACAA online examination system. Confirm the on-screen timer and count for your sitting.

How much does the SACAA PPL Meteorology exam cost?

Expect roughly R425–R450 per theoretical subject under current SACAA fee practice, but always verify the live Part 187 / SACAA fee schedule. Many ATOs add an invigilation or facility charge on top of the Authority fee.

What topics does SACAA PPL Meteorology cover?

The syllabus covers the atmosphere and ISA; pressure, density and temperature; humidity and precipitation; wind systems; clouds and fog; air masses and fronts; icing, thunderstorms and mountain hazards; Southern African climatology; altimetry; and interpretation of METAR, TAF, SPECI, SIGMET and weather charts.

How long are PPL theory passes valid?

All required PPL theoretical subjects must normally be passed within 18 months of the first examination pass. After the final theory pass, candidates typically have 36 months to complete the PPL skills test before theory credits expire.
