A. Adjust an input until the result falls within the target range and record only the final value.
B. Verify source data, units, assumptions, and limits; recalculate independently and document the checked result before using it.
C. Use the previous calculation unchanged even though one or more current inputs have changed.
D. Average conflicting results and accept the midpoint without checking the source data.
Correct Answer: B
Explanation: A result involving Normal, abnormal and emergency operating procedures integrated across the is only reliable when its
inputs, units, assumptions, and method are verified. An independent recalculation reduces the risk of carrying an unnoticed numerical
error into the decision.
2. Before accepting a calculated limit involving Mass, balance, takeoff, climb, cruise, landing and obstacle calculations within the

from two sources, with a 19% difference in the most critical value.
A. Ignore unit or assumption differences if the final number appears reasonable.
B. Confirm the current inputs and approved method, repeat the calculation with an independent reasonableness check, and resolve
any difference.
C. Average conflicting results and accept the midpoint without checking the source data.
D. Adjust an input until the result falls within the target range and record only the final value.
Correct Answer: B
Explanation: For Mass, balance, takeoff, climb, cruise, landing and obstacle calculations, changed inputs require a fresh calculation
using the approved method. Checking units and reasonableness makes the result reproducible and defensible.

traffic services as applied to is numerically defensible during a supervised practical activity? A sample of 34 items is examined; 4
show a different condition, and the supporting record is 63 hours old.
A. Validate measurements and inputs, apply the approved calculation method, compare the result with required limits, and retain the
calculation record.
B. Select the most favorable result from repeated calculations without investigating the variation.
C. Adjust an input until the result falls within the target range and record only the final value.
D. Ignore unit or assumption differences if the final number appears reasonable.
Correct Answer: A
Explanation: The safest numerical approach for Communications, airspace procedures and safe coordination with air traffic is to
validate source data and independently check the result before use. Selecting a favorable number without resolving differences is not
acceptable practice.
