What is the requirement for using the battery to power radios or beacons while stopped?

The correct choice regarding the requirement for using the battery to power radios or beacons while stopped indicates that it is permissible to do so for a duration of less than 15 minutes. This guideline is important for safety and operational efficiency on the airside, particularly at busy airports like Vancouver International Airport (YVR).

Using battery-powered equipment while stopped for a short duration helps maintain communication and visibility without needing to leave the vehicle running, which can contribute to unnecessary noise and emissions. The 15-minute guideline ensures that personnel can remain connected and responsive without significantly impacting the environment or operational safety.

It's crucial to adhere to this time limit as exceeding it could lead to increased risks associated with vehicle operation and could potentially violate airport regulations aimed at minimizing exhaust and promoting better air quality on the airside. Additionally, shorter stopped durations help ensure that vehicles can rejoin traffic flow promptly, which is vital in maintaining airport efficiency.
