Which of the following is an action that a C172 is NOT certified to perform?

The Cessna 172, like many general aviation airplanes, is not certified to operate under icing conditions. This means that the aircraft is not designed or equipped to safely fly in environments where ice can accumulate on the wings or other critical surfaces. The presence of ice can significantly degrade the performance of the aircraft, affecting lift, drag, and overall control.

Anti-icing and deicing procedures are typically intended for aircraft that are equipped with systems to prevent ice accumulation or to remove ice once it has formed. While a C172 may have some basic procedures for handling ice if a pilot finds themselves in icing conditions inadvertently, these are not part of its normal operational capabilities.

Standard flight operations refer to routine maneuvers and flight activities that the aircraft is fully certified to perform, which is why these are not in the realm of limitations. Understanding the operational limitations of an aircraft like the C172 is crucial for ensuring safety and compliance with aviation regulations.
