resolve the discrepancy rather than defer, bypass, or redefine the control.
13. A reviewer finds conflicting evidence about Normal, abnormal and emergency operating procedures for safe, accurate work in aviation knowledge and flight
during a pre-task planning review. What should happen first? Case EB-2660-0013: 8 checks are complete, 4 item(s) remain open, 4 supporting record(s) are
available, the last review was 22 hour(s) ago, and the current result differs from the prior baseline by 13 unit(s).
A. Use the previous calculation unchanged even though one or more current inputs have changed.
B. Ignore unit or assumption differences if the final number appears reasonable.
C. Confirm source data and allowable limits for Normal, abnormal and emergency operating procedures for safe, accurate work in aviation, repeat the
calculation with an independent check, and resolve any difference before acceptance.
D. Adjust an input until the result falls within the target range, then record only the final value.
Correct Answer: C
Explanation: The best answer verifies Normal, abnormal and emergency operating procedures for safe, accurate work in aviation against current requirements
and evidence before acceptance. With 4 open item(s), 4 supporting record(s), and a 13-unit change from baseline, a traceable foundational decision should
resolve the discrepancy rather than defer, bypass, or redefine the control.
14. A reviewer finds conflicting evidence about Mass, balance, takeoff, climb, cruise, landing and obstacle calculations through realistic aviation knowledge and
during a pre-task planning review. What should happen first? Case EB-2660-0014: 6 checks are complete, 1 item(s) remain open, 1 supporting record(s) are
available, the last review was 11 hour(s) ago, and the current result differs from the prior baseline by 11 unit(s).
A. Confirm source data and allowable limits for Mass, balance, takeoff, climb, cruise, landing and obstacle calculations through realistic, repeat the calculation
with an independent check, and resolve any difference before acceptance.
B. Average the conflicting results and accept the midpoint without checking the source data.
C. Select the most favorable result from repeated calculations without investigating the variation.
D. Ignore unit or assumption differences if the final number appears reasonable.
Correct Answer: A
Explanation: The best answer verifies Mass, balance, takeoff, climb, cruise, landing and obstacle calculations through against current requirements and
evidence before acceptance. With 1 open item(s), 1 supporting record(s), and a 11-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
15. A reviewer finds conflicting evidence about Communications, airspace procedures and safe coordination with air traffic services with emphasis on
boundaries and during a pre-task planning review. What should happen first? Case EB-2660-0015: 4 checks are complete, 2 item(s) remain open, 5 supporting
record(s) are available, the last review was 24 hour(s) ago, and the current result differs from the prior baseline by 9 unit(s).
A. Adjust an input until the result falls within the target range, then record only the final value.
B. Confirm source data and allowable limits for Communications, airspace procedures and safe coordination with air traffic services with, repeat the calculation
with an independent check, and resolve any difference before acceptance.
C. Proceed using an estimate even though the approved method and current inputs are available.
D. Select the most favorable result from repeated calculations without investigating the variation.
Correct Answer: B
Explanation: The best answer verifies Communications, airspace procedures and safe coordination with air traffic services against current requirements and
evidence before acceptance. With 2 open item(s), 5 supporting record(s), and a 9-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
