Difficulty: EasyDrawing Logical Conclusions

Passage:
During pre-flight testing on cargo aircraft, auxiliary cooling fans must remain active whenever instruments run on ground power. If internal avionics bay temperatures exceed 40°C, navigation processors automatically throttle performance to prevent heat damage, which triggers false diagnostic failure alerts. Consequently, technicians encountering diagnostic errors during warm weather testing must check cooling fan operation before swapping out expensive circuit cards.

Statement: Ensuring that the avionics bay temperature remains below 40°C prevents navigation processors from generating false diagnostic failure alerts.

Answer: Answer

Answer

True: Keeping the avionics bay temperature below 40°C prevents the processor throttling that generates false diagnostic alerts.
The passage links temperatures over 40°C directly to processor throttling and the resulting false diagnostic failure alerts. It is logically valid to conclude that preventing temperatures from reaching 40°C prevents this specific failure mode.

Step-by-Step Solution

1
Identify the cause of false diagnostic failure alerts described in the text.
Temperatures exceeding 40°C cause navigation processors to throttle performance, which generates false alerts.
Establishing the direct cause-and-effect chain is required to evaluate the validity of the statement.
2
Evaluate whether preventing the cause (temperatures exceeding 40°C) prevents the consequence (false alerts).
If temperatures do not exceed 40°C, the throttling condition that produces false alerts does not occur.
Deducing the logical converse of the conditional relationship confirms the statement is true.
