What must aircraft suitable for aerial application of pesticides be able to do?

The correct answer emphasizes that aircraft used for aerial application of pesticides must be designed to lift, transport, and disperse pesticides safely. This capability is crucial because the purpose of aerial application is to efficiently and effectively deliver pesticides to target areas while minimizing risks to people, the environment, and the pilot.

Aircraft must have specific modifications and equipment, such as sprayers or misters, to ensure that pesticides are applied uniformly and at the correct rates. It is also essential for the aircraft to maintain safety standards to prevent accidental spills or misapplication during flight. Therefore, the ability to handle and apply these substances properly is fundamental to the aerial application process.

The other options do not address the primary function of aircraft in this context. Flying at any altitude without restrictions does not reflect safety considerations; monitoring pesticide levels, while important, does not pertain to the application process itself; and storing a large amount of fuel, while sometimes relevant to operational range, is not a fundamental requirement directly related to the aerial application of pesticides.
