What should a pilot do if they experience unexpected turbulence during IFR flight?

When a pilot encounters unexpected turbulence during IFR flight, the appropriate response is to follow established turbulence protocols and maintain control of the aircraft. This involves ensuring that the airplane is properly configured for the conditions, which includes maintaining the proper airspeed to minimize the effects of turbulence and secure any loose items in the cockpit.

By focusing on control and following protocols, the pilot can ensure the safety of both the aircraft and its occupants. Maintaining a stable flight path allows the pilot to assess the situation more thoroughly, communicate with air traffic control if necessary, and make informed decisions about potential adjustments to altitude or route as the turbulence situation evolves.

Other options, such as immediately descending to a lower altitude or diverting to an alternate airport, may not be appropriate without understanding the severity and nature of the turbulence. Additionally, notifying passengers to brace for impact is typically reserved for situations where a significant risk is present, which may not be justified in cases of common turbulence. The key is to prioritize control and safety through a methodical and informed response to the turbulence encountered.
