Pilots can deviate from Air Traffic Control (ATC) clearances when they receive an amended clearance. This is crucial because an amended clearance indicates that ATC has provided new instructions that supersede the previous clearance, allowing the pilot to adjust their flight path or actions accordingly. Safety in aviation relies heavily on constant communication and adherence to instructions from air traffic controllers. An amended clearance often arises due to changes in traffic, weather conditions, or operational needs, ensuring that pilots have the most current information to operate their flight safely.

The other options do not provide a valid reason for pilots to deviate. Clear views, clear conditions, or the situation surrounding a busy airport do not constitute a directive from ATC and, therefore, cannot be used as a basis for deviating from established clearances. Pilots must prioritize adhering to ATC instructions unless a new directive has been issued, ensuring safety and coordination within the airspace.
