Maximum flap speeds (UA limits) are:

The maximum flap speeds, also known as VFE, are critical parameters for safe flight operations during the extension and retraction of flaps. In the context of the A320 aircraft, each flap position has a corresponding maximum speed limit to ensure safe handling and control of the airplane while flaps are deployed.

The speeds for flap extension on the A320, correlating to different flap positions, are specified as follows: initial flap extension, intermediate flap settings, and full flaps. When referencing the options available, the values in the correct answer reflect the specific limits that have been established for the A320 model, which are critical for maintaining operational safety and performance.

The choices provided include various limits that are not consistent with the established data for the A320 model. The inclusion of 220, 205, 190, 175, and 167 in the correct answer aligns with the manufacturer's specifications and regulatory standards for the flap operation speed limits. This ensures that pilots are aware of maximum speeds to prevent structural damage or loss of control when the flaps are extended, particularly during critical phases of flight such as approach and landing.
