What should be kept on hand to ensure readiness for operations?

• A. Fresh fruit and snacks for crew.
• B. A marketing brochure.
• C. Spare parts and supplies such as nozzles, hoses, fittings, drive belts, fuel, and lubricants.
• D. A second aircraft for backups.

Answer: (C)

Being prepared for operations means having maintenance and repair stock on hand so equipment can stay in service with minimal downtime. Spare parts and supplies like nozzles, hoses, fittings, drive belts, fuel, and lubricants directly support this readiness. Nozzles and hoses wear, clog, or leak, which can change spray performance or stop application; having replacements keeps the spray pattern, flow, and rate consistent and safe. Fittings ensure tight, leak-free connections, preventing losses and hazards. Drive belts can wear or fail, and having spares means pumps and other moving parts keep running. Fuel keeps the engine and equipment operating, while lubricants protect components from wear and overheating. In the field, you can’t rely on immediate replacements from elsewhere, so having these items on hand minimizes downtime and helps maintain safe, effective operation. The other options don’t directly keep equipment ready for spraying in the field.
