What is indicated by BTMS indicators before initiating taxi?

• A. They should all be red
• B. They must all be green and not increasing
• C. They can be any color
• D. They should only show average temperatures

Answer: (B)

The requirement for BTMS (Battery Temperature Monitoring System) indicators to all be green and not increasing before initiating taxi is essential for ensuring the safety and operational readiness of the aircraft. Green indicators signify that the battery temperatures are within an acceptable range, indicating that the battery is not overheating. This is crucial as elevated temperatures can lead to battery malfunction or even fire hazards during flight operations. Having all indicators green ensures that the crew can confidently proceed with taxiing, knowing that the battery system is functioning properly and is within safe temperature limits. If any of the indicators were red, it would indicate a potential issue requiring immediate attention before taxi can be safely commenced. Therefore, the emphasis on both color and stability (not increasing) aligns with safety protocols essential to aviation operations, helping prevent incidents related to overheated batteries.
