What condition must be met for the aircraft allowed at Santa Rosa?

• A. 12-5 left, 4 right, 3 low
• B. All must be less than 10
• C. All must be powered
• D. None can be over 5

Answer: (A)

The correct answer highlights specific operational limitations placed on aircraft at Santa Rosa Airport. The condition "12-5 left, 4 right, 3 low" refers to the maximum allowable weights or dimensions (commonly turning radii or weights) for the types of aircraft. This kind of limitation is crucial in determining which aircraft can safely operate at a given airport based on factors like runway size, structural limits of the facilities, and air traffic management protocols.

For example, if the weights or certain performance metrics of aircraft exceed these limits, it could compromise safety or cause operational issues, such as difficulties in takeoff, landing, or taxiing. Hence, ensuring aircraft meet the specified conditions is vital for maintaining safe airport operations.

The other options do not accurately reflect this necessary operational standard for aircraft at Santa Rosa Airport. Specific numerical thresholds like weights or dimensions matter significantly when assessing safety and performance capabilities of various aircraft types.
