What minimum distance must be available for landing when using heavy weight flaps in the T-6A?

The minimum distance required for landing using heavy weight flaps in the T-6A is 4,000 feet. This specification is based on the aircraft's operational limits, which ensure safe landings under specific conditions. When utilizing heavy weight flaps, the requirement for a longer landing distance helps accommodate the increased stall speed and potential for a higher landing speed due to the extra weight. This ensures that pilots have enough runway length to execute a safe landing, factoring in necessary stopping distance and margins for safety.

Understanding these operational limits is crucial for pilots operating the T-6A, as they must recognize how weight and flap settings affect landing performance. The other distances provided in the options do not meet the prescribed safety thresholds established for the T-6A under heavy weight landing configurations, making the 4,000 feet the correct requirement for ensuring a safe landing.
