What functions actively maintain helicopter parameters, such as airspeed and altitude?

• A. Outer loop
• B. Inner loop
• C. Mechanical
• D. Computer

Answer: (A)

The outer loop is responsible for maintaining broader flight parameters, such as airspeed and altitude, through various control inputs. This system takes higher-level commands or pilot inputs regarding performance and translates these into appropriate control actions. The outer loop typically operates at a slower response rate compared to other systems, allowing it to focus on stabilizing the aircraft and achieving desired flight paths over longer periods.

The inner loop, in contrast, is primarily concerned with maintaining immediate dynamics of the helicopter, such as the precise control of pitch, roll, and yaw, responding quickly to changes to ensure stability. Mechanical systems involve the physical components that contribute to flight but do not actively maintain parameters autonomously. The computer can play a role in processing inputs and assisting with calculations but is not a direct control system for maintaining flight parameters like the outer loop.

By understanding these roles, it's clear that the outer loop is integral to the active management of critical helicopter parameters during flight.
