Final answer:
The lowest altitude permitted for acrobatic flight is 1,500 feet AGL, as stated in the Federal Aviation Regulations for safety and operational standards.
Step-by-step explanation:
The question, 'What is the lowest altitude permitted for acrobatic flight?' pertains to aviation law and regulations concerning flight safety and operation standards. According to the Federal Aviation Regulations (FARs), the lowest altitude permitted for acrobatic flight is 1,500 feet Above Ground Level (AGL). It is essential for pilots to adhere to this regulation to maintain safety for themselves and any individuals or property on the ground. This altitude allows for a safe margin in case of unexpected issues during acrobatic maneuvers and ensures that pilots have enough space to recover from a flight abnormality before it could lead to an incident.
