ATSA Numerical Memory and Differences 4 — Questions and Answers
Question 1: A departure time is 1748Z and the estimated flight time is 2 hours 35 minutes. What is the estimated arrival time?
- 1913Z
- 2023Z (Correct answer)
- 2013Z
- 2123Z
Correct answer: 2023Z
1748 + 2h35m = 2023Z.
Question 2: You memorize four squawk codes: 2643, 2634, 2346, 2364. Which code has the digit 6 in the second position?
- 2643 (Correct answer)
- 2634
- 2346
- 2364
Correct answer: 2643
In 2643, position two (from left) is 6.
Question 3: An aircraft requests FL390 but is assigned FL370. How many feet below the requested altitude is the assigned altitude?
- 1,000 ft
- 1,500 ft
- 2,000 ft (Correct answer)
- 2,500 ft
Correct answer: 2,000 ft
FL390 is 39,000 ft and FL370 is 37,000 ft; the difference is 2,000 ft.
Question 4: A speed sequence reads: 280, 265, 250, 235. If the pattern continues, what is the next value?
- 225
- 220 (Correct answer)
- 215
- 210
Correct answer: 220
The sequence decreases by 15 each step; 235 − 15 = 220.
Question 5: Two aircraft have beacon codes 4573 and 4537. Which digit position differs between them?
- Position 1
- Position 2
- Position 3 (Correct answer)
- Position 4
Correct answer: Position 3
Codes 4573 and 4537 differ at position 3: 7 vs 3.
Question 6: A list of five frequencies is presented: 119.1, 118.9, 119.3, 118.7, 119.0. Which frequency is the median?
- 118.9
- 119.0
- 119.1 (Correct answer)
- 118.7
Correct answer: 119.1
Sorted: 118.7, 118.9, 119.0, 119.1, 119.3 — the median (middle) is 119.0.
Question 7: You see the number 58274 displayed briefly. Later you are asked to identify the number with those exact digits rearranged: 52874. Which digit changed its position the most?
- 5
- 2 (Correct answer)
- 8
- 7
Correct answer: 2
The digits 8 and 2 swapped positions (positions 2 and 3), making digit 2 the answer as it moved from 3rd to 2nd place.
