What should a pilot do if they encounter a thunderstorm along their flight path?

When encountering a thunderstorm along a flight path, the most advisable action is to divert around the storm if possible. Thunderstorms present numerous hazards, including turbulence, hail, lightning, and severe wind shear, which can significantly endanger the safety of the flight. Diverting around a storm allows the pilot to maintain control of the aircraft and avoid these dangerous conditions, contributing to the safety of both the flight crew and passengers.

In practice, pilots are trained to recognize weather conditions and hazards ahead of time. Using radar and weather reports, they can plan a route that avoids severe weather. It's essential to have the flexibility to alter the flight path when thunderstorms are involved, as flying through them can expose the aircraft to extreme turbulence and other hazards that could lead to loss of control.

While climbing to a higher altitude or requesting assistance from EFAS (En Route Flight Advisory Service) could be considered in different scenarios, they do not provide a direct solution to the immediate danger posed by thunderstorms. Climbing might not clear the storm's violent conditions, and seeking assistance would not resolve the urgency of the hazardous weather. Thus, the preferred and safest course of action when a pilot encounters a thunderstorm is to divert around it.
