Describe the primary flight instruments found in the TH-73A cockpit.

• A. Only the altimeter and airspeed indicator
• B. GPS, altimeter, and vertical speed indicator
• C. Airspeed indicator, altimeter, attitude indicator, and heading indicator
• D. Magnetic compass, heading indicator, and fuel gauge

Answer: (C)

The primary flight instruments in the TH-73A cockpit include the airspeed indicator, altimeter, attitude indicator, and heading indicator. Each of these instruments plays a crucial role in the operation and navigation of the aircraft.

The airspeed indicator provides critical information about the aircraft's speed relative to the surrounding air, which is essential for maintaining safe flight operations, particularly during takeoff, landing, and while executing maneuvers. The altimeter continuously measures the aircraft's altitude above sea level, which is vital for maintaining safe vertical separation from terrain and other obstacles. The attitude indicator displays the aircraft's orientation relative to the horizon, helping pilots maintain control of the aircraft's pitch and roll. Finally, the heading indicator shows the aircraft's current direction, allowing pilots to navigate accurately and maintain their flight path.

This combination of instruments gives pilots comprehensive situational awareness regarding speed, altitude, orientation, and direction, which are all crucial for safe and effective flight operations. Other options do not encompass the full set of primary flight instruments necessary for effective cockpit management.
