Which atmospheric condition is listed in FO restrictions for pilots with less than 100 hours?

• A. Wind shear reported in vicinity
• B. Thunderstorms nearby
• C. Turbulence aloft
• D. Low visibility

Answer: (A)

Wind shear is singled out because it can produce sudden and unpredictable changes in airspeed and flight path, especially during takeoff and landing. For pilots with less than 100 hours, managing those abrupt changes is very challenging, so the policy confines operations where wind shear in the vicinity has been reported. That specific restriction directly addresses the most dangerous, high-risk scenario for someone early in their training.

The other conditions—thunderstorms nearby, turbulence aloft, and low visibility—are all hazardous in general, but they are not the particular restriction highlighted for this low-hour category. They may be managed under broader weather minimums or other guidelines, whereas wind shear in the vicinity is the specific restriction called out for this level of experience.
