Increasing the throttle in a helicopter primarily affects several performance aspects, including torque, speed, and fuel consumption. When the throttle is increased, the engine produces more power, which increases the rotor speed, leading to greater torque. This torque is necessary to maintain balance and control in flight, especially when climbing or flying against the wind.

Furthermore, an increase in engine power translates into higher speed capabilities, allowing the helicopter to gain more lift and cover ground more quickly. Fuel consumption is also directly affected because an increase in throttle results in the aircraft using more fuel to sustain the additional power output.

In contrast, the push rate is not directly influenced by changes in throttle settings. The term "push rate" typically refers to the rate at which an aircraft can accelerate or climb, which is more related to factors such as aircraft weight, rotor effectiveness, and environmental conditions, rather than just throttle input. Thus, while increasing throttle enhances power and capabilities, the push rate remains relatively unaffected solely by throttle adjustments.
