APR power initiated by the AUTO system is limited to how many minutes?

The correct duration for APR power initiated by the AUTO system is 10 minutes. This limit is designed to ensure that the system can operate effectively within a controlled timeframe, optimizing performance and maintaining safety. The 10-minute cap allows sufficient time for necessary operations without risking system overload or battery depletion.

The decision to set this timeframe is based on operational efficiency and reliability standards within the training context of DFW Instructors 300/350. It's important to remember that knowing this limitation is critical for ensuring proper handling of the conditions when the AUTO system activates APR power, as exceeding the specified duration could lead to system malfunctions or other operational issues.
