What is the maximum bank angle at which aerobatics are prohibited?

• A. 45 degrees
• B. 60 degrees
• C. 30 degrees
• D. 90 degrees

Answer: (B)

This limit protects the airframe and handling by keeping you within the airplane’s approved flight envelope. In the DA20-C1, aerobatic maneuvers are not allowed once the bank angle exceeds 60 degrees. Keeping the bank at or below 60 degrees helps manage structural loads and maintain controllability, since the load factor increases with bank angle (approximately 1 divided by the cosine of the bank angle). At 60 degrees, the load factor in level flight is about 2g, and beyond that the stresses rise quickly and the airplane is no longer certified for those maneuvers. So, the maximum bank angle at which aerobatics are prohibited is 60 degrees.
