Under FAR23, which maneuver is not allowed for a Normal Category aircraft?

The maneuver that is not allowed for a Normal Category aircraft, as per FAR Part 23, is steep turns with a bank angle of more than 60 but less than 90 degrees. Normal Category aircraft are designed primarily for flights that are conducted in a typical operational environment, which includes limitations on their performance capabilities and structural integrity.

In this category, the permissible maneuvers are restricted to ensure safety and maintain the structural integrity of the aircraft during flight. Steep turns, particularly those exceeding a bank angle of 60 degrees, subject the aircraft to increased loads and could potentially lead to structural failure or loss of control if the aircraft is not designed to withstand such stress.

The other maneuvers listed, such as stalls (excluding whip stalls), chandelles, and lazy eights, are within the operational limits defined for Normal Category aircraft, as they are not considered excessively demanding and can typically be performed within the parameters set forth in the regulations. Stalls and the specific types of turns mentioned may be included under controlled training conditions that do not exceed the aircraft's designed limits.

Thus, the restriction on steep turns exceeding 60 degrees appropriately reflects the need for safety and the structural limitations of Normal Category aircraft, making it the correct answer to
