ATSA - Air Traffic Skills Assessment Numerical Memory and Differences Questions and Answers — Questions and Answers
Question 1: In the ATSA Numerical Memory and Differences section, a sequence of numbers is displayed. If the number 8 is shown, followed by the number 3, and after you input the correct difference the number 9 appears, what is the next difference you must input?
- 1
- 6 (Correct answer)
- 5
- 2
Correct answer: 6
The task is to find the positive difference between the most recent number displayed (9) and the number displayed immediately before it (3). The difference between 9 and 3 is 6. A common error is to calculate the difference between the new number (9) and the previous answer (which was 5).
Question 2: A candidate is taking the Numerical Memory and Differences test. The first number shown is 4. The second number shown is 9. What is the correct value the candidate should input?
- 3
- 13
- 5 (Correct answer)
- 4
Correct answer: 5
The test requires you to calculate the positive difference between the two numbers presented. The difference between 9 and 4 is 5.
Question 3: Which of the following describes the primary task in the Numerical Memory and Differences section of the ATSA?
- Adding a sequence of single-digit numbers.
- Memorizing a long string of numbers and recalling it later.
- Calculating the running total of a series of numbers.
- Sequentially calculating the positive difference between the last two numbers shown. (Correct answer)
Correct answer: Sequentially calculating the positive difference between the last two numbers shown.
This section specifically tests your ability to hold one number in short-term memory, view the next number, and quickly calculate the positive difference between those two specific numbers in a continuous sequence.
Question 4: During the Numerical Memory and Differences test, what is a critical error that test-takers must avoid?
- Calculating the difference between the new number and their previous typed answer. (Correct answer)
- Using the standard keyboard numbers instead of the numeric keypad.
- Forgetting the very first number in the entire sequence.
- Calculating the sum instead of the difference.
Correct answer: Calculating the difference between the new number and their previous typed answer.
A frequently cited error is confusing the last number shown on the screen with the answer just typed in. You must always calculate the difference between the two most recent numbers presented visually, not your own previous input.
Question 5: In a given sequence, the numbers 2, 7, and then 1 are shown consecutively. What are the correct two answers you must input in order?
- 5, then 1
- 5, then 6 (Correct answer)
- 9, then 6
- 5, then 4
Correct answer: 5, then 6
First, the difference between the initial pair (2 and 7) is 5. After that is entered, the next pair to consider is the 7 and the 1. The positive difference between 7 and 1 is 6. Therefore, the correct sequence of answers is 5, then 6.
Question 6: What is the specific range of the individual numbers that appear on the screen during the Numerical Memory and Differences test?
- 0-9
- 1-10
- 1-9 (Correct answer)
- 0-10
Correct answer: 1-9
The parameters for this ATSA section state that the numbers presented will be single digits ranging from 1 to 9.
