What type of navigation aids are included in TH-73A operations?

• A. Only visual flight rules landmarks
• B. GPS, VOR, and DME
• C. Chart plotters and radar systems
• D. Magnetic compasses and echosounders

Answer: (B)

The inclusion of GPS, VOR (VHF Omnidirectional Range), and DME (Distance Measuring Equipment) in TH-73A operations reflects the reliance on modern navigational technologies that provide precise location and navigation information.

GPS is widely utilized in aviation for accurate positioning and navigation, allowing pilots to determine their exact location and track their route efficiently. VOR is a ground-based navigation system that enables aircraft to determine their bearing relative to a VOR station, which is critical during both en route and approach phases of flight. DME complements VOR by providing distance information to enhance situational awareness and improve navigation accuracy.

These navigation aids are essential for flight safety and operational efficiency, aligning with current practices in aviation training and operations. The combination of these technologies enables pilots flying the TH-73A to maintain situational awareness and navigate effectively in various flight conditions.

In contrast, the other options either focus solely on less robust navigational systems or do not represent the comprehensive suite of aids employed in the TH-73A. Visual flight rules landmarks, while useful, do not provide the same level of operational reliability as electronic navigational aids. Chart plotters and radar systems, though valuable in certain contexts, are not primary navigation aids for the TH-
