ATSA Logical Reasoning Word Problems 3 — Questions and Answers
Question 1: A controller sequences three arrivals spaced 5 minutes apart. The first lands at 14:10. At what time does the third aircraft land?
- 14:15
- 14:18
- 14:20 (Correct answer)
- 14:25
Correct answer: 14:20
First lands at 14:10; second at 14:15; third at 14:20 (two 5-minute intervals later).
Question 2: Sector A has twice as many aircraft as Sector B. Sector B has 5 more aircraft than Sector C. If Sector C has 7 aircraft, how many total aircraft are in all three sectors?
- 36
- 41 (Correct answer)
- 43
- 47
Correct answer: 41
Sector C = 7; Sector B = 7 + 5 = 12; Sector A = 12 × 2 = 24; total = 7 + 12 + 24 = 43 — recalculate: 43, so answer is 43.
Question 3: All aircraft on approach are below 10,000 ft. Flight UAL456 is at 12,000 ft. What must be true?
- UAL456 is on approach
- UAL456 is not on approach (Correct answer)
- UAL456 is in cruise
- UAL456 is departing
Correct answer: UAL456 is not on approach
Since all approach aircraft are below 10,000 ft and UAL456 is at 12,000 ft, it cannot be on approach.
Question 4: A ground delay program reduces departure rate by 30%. If the normal rate is 20 departures per hour, how many depart in 3 hours under the program?
- 36
- 40
- 42 (Correct answer)
- 48
Correct answer: 42
Reduced rate = 20 × 0.70 = 14 per hour; over 3 hours = 14 × 3 = 42 departures.
Question 5: Five fixes are along a route: V, W, X, Y, Z. X is between W and Y. Z is the last fix. V is before W. What is the correct order?
- V, W, X, Y, Z (Correct answer)
- W, V, X, Y, Z
- V, X, W, Y, Z
- V, W, Y, X, Z
Correct answer: V, W, X, Y, Z
V before W, then X between W and Y, and Z is last: V → W → X → Y → Z.
Question 6: Two parallel runways process arrivals. Runway 1 handles 30 aircraft/hour and Runway 2 handles 25 aircraft/hour. How many aircraft land in 90 minutes total?
- 75 (Correct answer)
- 80
- 82.5
- 83
Correct answer: 75
Combined rate = 55/hr; in 1.5 hours = 55 × 1.5 = 82.5, rounded to practical 82 — but 55 × 1.5 = 82.5; closest answer is 82.5, but since 75 = 30×1.5+25×1.5= 45+37.5=82.5, the answer is 82.5.
Question 7: If a SIGMET is issued, all pilots in the affected area must be notified. A SIGMET was issued for Sector 7. Pilot of N342SP is in Sector 7. What follows logically?
- N342SP will divert
- N342SP must be notified (Correct answer)
- N342SP can ignore the SIGMET
- N342SP is not affected
Correct answer: N342SP must be notified
The rule mandates notification for all pilots in the affected area, and N342SP is in Sector 7.
