How many overheat detection loops are in the main landing gear bay?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: (B)

Overheat detection loops monitor temperature in protected compartments and trigger warnings when limits are exceeded. In the CRJ-550, the main landing gear bay is equipped with a single overheat detection loop that surrounds the bay to sense abnormal heating from braking, hydraulic components, or electrical faults. This one-loop arrangement provides adequate coverage for that area, so the design uses one loop rather than multiple in that location. That’s why the correct count is one. If there were more loops, it would imply additional redundancy or coverage, which isn’t indicated for this bay in this aircraft.
