What are the required preflight inspections for the TH-73A?

• A. Only cockpit checks
• B. Only external checks
• C. External checks, cockpit checks, and systems checks
• D. Only systems checks

Answer: (C)

The correct answer encompasses all necessary preflight inspections for the TH-73A, which includes external checks, cockpit checks, and systems checks. Each of these inspections plays a critical role in ensuring the safety and functionality of the aircraft prior to flight.

External checks are vital as they allow the pilot to assess the condition of the aircraft's structure, control surfaces, and other essential exterior components. This includes looking for obvious signs of damage or wear that could affect the aircraft's performance.

Cockpit checks involve verifying the functionality of instruments, controls, and other crucial equipment within the cockpit. This ensures that all systems are operational and the pilot will have the information necessary for safe flight operations.

Lastly, systems checks are conducted to ensure that all internal systems, such as electrical and hydraulic systems, are functioning properly. This thorough assessment helps identify any potential issues that could arise during flight.

Together, these three components of the preflight inspection ensure that the TH-73A is fully prepared for safe operation, mitigating risks and promoting operational readiness. In contrast, focusing on only one aspect, such as cockpit checks or external checks alone, would leave potential safety vulnerabilities unaddressed, thereby increasing the risk during flight.
