At what altitude does Sunfish airspace extend to?

Sunfish airspace extends up to 3500 feet MSL (Mean Sea Level). This altitude is significant because it defines the vertical limits of the airspace designated for specific uses, such as training or air traffic control. It helps in managing air traffic effectively within that zone by ensuring that pilots are aware of their operational parameters and that they maintain the necessary altitude for safety reasons.

Understanding the specific altitude limit is crucial for pilots and air traffic personnel when navigating in and around that airspace. It ensures compliance with regulations and contributes to overall flight safety. The other choices represent altitudes higher than the defined limit for Sunfish airspace, which would be outside its designated vertical range.
