In the event of a prime power failure, how many minutes does the internal battery in the AN/TPN-19 Landing Control Central (LCC) allow for full power load?

The internal battery of the AN/TPN-19 Landing Control Central (LCC) is designed to support a full power load for a duration of 10 minutes in the event of a prime power failure. This feature is crucial for maintaining operational integrity during temporary power outages, ensuring that critical systems remain functional for a brief period. The 10-minute timeframe provides sufficient operational continuity while allowing time for measures to be taken to restore power or to switch to backup systems. This value is based on the understanding that a short run time is necessary while not being overly burdensome on the battery, balancing performance and battery life.
