Why should battery connectors and contacts be inspected for oxidation and cleanliness during preflight?
- A.Corroded or dirty contacts can cause unreliable electrical connection and power loss
- B.Oxidation improves conductivity once the battery warms up
- C.Connector condition only affects how fast the battery charges on the ground
Correct answer
A. Corroded or dirty contacts can cause unreliable electrical connection and power loss
Why
Power contacts carry the full current used in flight, so oxidation, dirt, or damage can interrupt power. Cleaning or removing a defective pack or connector from service protects against a sudden power failure.
