How many knots prior to the stall does the artificial stall warning activate?

The artificial stall warning in the T-6A activates when the aircraft is approaching the stall condition, specifically at a margin of 5-10 knots above the stall speed. This warning is designed to alert the pilot to the impending risk of a stall, allowing them to take corrective actions before reaching the actual stall point. The activation range ensures that pilots are sufficiently warned to maintain safe flight parameters while still allowing for some margin of safety. Understanding this threshold is crucial for managing the aircraft's performance and ensuring safety during flight operations.
