During landing operations, if a convective storm is detected near the runway, which action is appropriate?

• A. In-flight entertainment.
• B. Landing and takeoff performance.
• C. Flight plan filing.
• D. Crew rest requirements.

Answer: (B)

When convective weather is near the runway, the main concern is how it changes aircraft performance during landing or takeoff. Storms can bring strong, gusty winds, wind shear, microbursts, turbulence, and reduced visibility, along with possible runway contamination from rain or hail. All of these factors can significantly increase the required landing distance and reduce braking effectiveness or aircraft controllability. The appropriate action is to re-evaluate and update landing and takeoff performance using the latest weather information and performance data. This means recalculating speeds, flaps, and configuration, assessing the required runway length on the current runway condition, and deciding whether a safe landing or takeoff is possible, or if a go-around or diversion is necessary. Other actions like unrelated in-flight entertainment or filing a flight plan or addressing crew rest do not address the immediate safety concerns posed by the storm near the runway.
