At what altitude does DWAT de-arm?

At what altitude does DWAT de-arm?

• A. Immediately after landing
• B. Upon reaching 10,000 ft MSL
• C. When the aircraft reaches cruising altitude
• D. After 3 minutes of flight

Answer: (B)

The correct answer indicates that DWAT (Data Write Acknowledge Timer) de-arms upon reaching 10,000 feet Mean Sea Level (MSL). This altitude is significant in aviation because it is commonly associated with various operational transitions. For most aircraft, this altitude marks the boundary between the lower and upper levels of airspace and serves as a critical threshold for maintaining operational safety and managing aircraft systems effectively. By de-arming at 10,000 feet, the system ensures that data recordings and potential write operations are paused to prevent anomalies that could occur at lower altitudes, where the flight characteristics can change more rapidly and require constant monitoring. Moreover, this operational procedure aligns with regulatory and safety protocols that dictate performance and equipment changes as aircraft ascend through different altitude levels. In contrast, stating that DWAT de-arms immediately after landing or after three minutes of flight does not accurately reflect the standard practices corresponding to altitude thresholds. Additionally, specifying that DWAT de-arms when the aircraft reaches cruising altitude could imply varying definitions of cruising altitude, which may not consistently revolve around the critical 10,000 ft benchmark that governs multiple operational protocols in aviation.
