,1. Which action best reduces the risk of a unit, input, or assumption error involving Mass, balance, takeoff, climb, cruise, landing and
obstacle calculations with decisions and during a supervised practical activity? The current review covers 34 records; 2 still require
follow-up, and the latest verification was completed 35 hours ago.
A. Use the previous calculation unchanged even though one or more current inputs have changed.
B. Select the most favorable result from repeated calculations without investigating the variation.
C. Proceed using an estimate even though current source data and the approved method are available.
D. Validate measurements and inputs, apply the approved calculation method, compare the result with required limits, and retain the
calculation record.
Correct Answer: D
Explanation: The safest numerical approach for Mass, balance, takeoff, climb, cruise, landing and obstacle calculations is to validate
source data and independently check the result before use. Selecting a favorable number without resolving differences is not
acceptable practice.
2. Which step is most important when checking a calculation involving Communications, airspace procedures and safe coordination
with air traffic services for safe during final verification before release or acceptance? The latest measurement is 8% different from the
prior verified value, while 3 supporting record(s) await confirmation.
A. Average conflicting results and accept the midpoint without checking the source data.
B. Pause the dependent decision, reconcile changed inputs, recalculate using the current method, and obtain a second check for
critical results.
C. Proceed using an estimate even though current source data and the approved method are available.
D. Use the previous calculation unchanged even though one or more current inputs have changed.
Correct Answer: B
Explanation: Calculations for Communications, airspace procedures and safe coordination with air traffic depend on current data and
controlled assumptions. Reconciliation and a second check are appropriate before the result supports acceptance or release.
3. Which action best reduces the risk of a unit, input, or assumption error involving Aerodynamic forces, stability, control and aircraft
performance relationships through realistic during pre-task planning? Before release, 19 checks are reviewed and 4 remain open
even though the scheduled decision is due within 69 hours.
A. Verify source data, units, assumptions, and limits; recalculate independently and document the checked result before using it.
B. Adjust an input until the result falls within the target range and record only the final value.
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: A
Explanation: A result involving Aerodynamic forces, stability, control and aircraft performance 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.

,4. Which step is most important when checking a calculation involving Airframe, powerplant, electrical, hydraulic, pneumatic and
flight-control systems with emphasis on during a field or operational inspection? The responsible practitioner receives 32 observations
from two sources, with a 9% difference in the most critical value.
A. Ignore unit or assumption differences if the final number appears reasonable.
B. Average conflicting results and accept the midpoint without checking the source data.
C. Confirm the current inputs and approved method, repeat the calculation with an independent reasonableness check, and resolve
any difference.
D. Adjust an input until the result falls within the target range and record only the final value.
Correct Answer: C
Explanation: For Airframe, powerplant, electrical, hydraulic, pneumatic and flight-control, changed inputs require a fresh calculation
using the approved method. Checking units and reasonableness makes the result reproducible and defensible.
5. Which action best reduces the risk of a unit, input, or assumption error involving Cockpit instruments, indications, limitations and
recognition of system faults for defensible during a routine quality-control review? A sample of 45 items is examined; 6 show a
different condition, and the supporting record is 31 hours old.

C. Ignore unit or assumption differences if the final number appears reasonable.
D. Validate measurements and inputs, apply the approved calculation method, compare the result with required limits, and retain the
calculation record.
Correct Answer: D
Explanation: The safest numerical approach for Cockpit instruments, indications, limitations and recognition of system is to validate
source data and independently check the result before use. Selecting a favorable number without resolving differences is not
acceptable practice.
6. Which step is most important when checking a calculation involving Air law, licensing privileges, operational limitations and required
documents including recognition during a shift or responsibility handover? The field condition and the approved record agree on most
points, but 1 of 17 checked elements require reconciliation.
A. Proceed using an estimate even though current source data and the approved method are available.
B. Ignore unit or assumption differences if the final number appears reasonable.
C. Select the most favorable result from repeated calculations without investigating the variation.
D. Pause the dependent decision, reconcile changed inputs, recalculate using the current method, and obtain a second check for
critical results.
Correct Answer: D
Explanation: Calculations for Air law, licensing privileges, operational limitations and required depend on current data and controlled
assumptions. Reconciliation and a second check are appropriate before the result supports acceptance or release.
