Basic TSA Practice 1 — Questions and Answers

Question 1: What is the difference between the February and May flight counts for ≥ 4 tonnes of cargo?

108
133 (Correct answer)
50
84

Correct answer: 133

To find the difference, locate the flight counts for cargo weighing 4 tonnes or more for both February and May from the provided data. Subtract the smaller value from the larger value to determine the absolute difference. This calculation reveals the change in the volume of heavier cargo flights between these two months.

Question 2: What is the percentage of aircraft carrying ≥ 8 tonnes in April as opposed to May?

1:0.92
1:1.09
1.09:1 (Correct answer)
1:1.92

Correct answer: 1.09:1

To determine the ratio of aircraft carrying 8 tonnes or more in April compared to May, divide the number of such flights in April by the number in May. This calculation expresses April's count as a proportion of May's, indicating how much larger or smaller April's volume was relative to May's. The result is then presented in the format X:1.

Question 3: What percentage of aircraft in March had cargo that weighed 3.99 pounds or less?

55.4%
62.8%
36.1%
44.6% (Correct answer)

Correct answer: 44.6%

To find the percentage, first identify the total number of flights in March and the number of flights carrying cargo weighing less than 4 tonnes (i.e., 3.99 tonnes or less) in March. Then, divide the number of flights with lighter cargo by the total number of flights in March and multiply by 100 to express it as a percentage. This shows the proportion of flights carrying lighter loads during that month.

Question 4: How many flights carrying cargo weighing at least six tonnes were there in February and March, on a percentage basis?

24.05%
30.1%
11.27% (Correct answer)
16.05%

Correct answer: 11.27%

First, sum the number of flights carrying 6 tonnes or more for both February and March. Next, calculate the combined total number of flights for both months. Finally, divide the combined number of heavy cargo flights by the combined total flights and multiply by 100 to get the percentage. This provides the overall proportion of heavy cargo flights across these two months.

Question 5: What was the ratio of category 1 to category 2 hurricanes in 2020?

1:0.52
1:0.63 (Correct answer)
1:0.15
1:0.46

Correct answer: 1:0.63

To determine the ratio, locate the number of Category 1 and Category 2 hurricanes that occurred in 2020 from the provided data. Divide the count of Category 1 hurricanes by the count of Category 2 hurricanes. This calculation expresses the relationship between the two categories, showing how many Category 1 hurricanes there were for every one Category 2 hurricane.

Question 6: What was the difference in percentage terms between category 3 hurricanes in 2025 and 2025?

22.22% decrease (Correct answer)
77.78% increase
28.57% decrease
125% increase

Correct answer: 22.22% decrease

This question is unanswerable as written, as it asks for a percentage difference between category 3 hurricanes in '2025 and 2025', implying a comparison of the same year to itself, which would yield a 0% difference. Assuming there is a typo and the question intended to compare 2025 to a previous year (e.g., 2024), a 22.22% decrease would mean the number of hurricanes in 2025 was 22.22% lower than in the comparison year. For example, if there were 9 hurricanes in the previous year and 7 in 2025, the decrease would be (9-7)/9 = 2/9 = 22.22%.

Question 7: What percentage of all hurricanes in 2025 were classified as 2 or 4?

38%
42%
24%
32% (Correct answer)

Correct answer: 32%

This question requires specific data on the number of hurricanes in each category for 2025, which is not provided in the prompt. To calculate the percentage, one would need to sum the number of Category 2 and Category 4 hurricanes in 2025, then divide that sum by the total number of all hurricanes in 2025. Multiplying this result by 100 would give the percentage. For instance, if there were 5 Category 2 and 3 Category 4 hurricanes, out of a total of 25 hurricanes, the calculation would be ((5+3)/25) * 100 = (8/25) * 100 = 32%.
