Final answer:
The two elements of control for basic instrument maneuvers in aviation are attitude control, which adjusts the aircraft's orientation, and power control, for managing engine power and airspeed.
Step-by-step explanation:
The two elements of control when performing basic instrument maneuvers in aviation are attitude control and power control.
Attitude control involves adjusting the aircraft's pitch, roll, and yaw to attain and maintain the desired flight path. On the other hand, power control refers to managing the engine power to achieve and sustain the desired airspeed and performance.
Together, these elements are crucial for maintaining straight and level flight, executing turns, climbs, and descents, and ensuring overall aircraft stability.
