Question

which of the following are ways that a control input can be transmitted to a control surface? select all that apply. (5.b.1) hydraulic pressure wind tunnels electronic signals anti - torque pedals cable and pulley during an approach to a stall, an increased load factor will cause the aircraft to ______. (5.c.2) stall at a higher airspeed. stall at a lower airspeed. have a tendency to spin. be more difficult to control.

Explanation:

First Question (Multiple Select)

• Hydraulic pressure: Used in aircraft control systems to transmit control inputs to surfaces (e.g., hydraulic actuators).
• Electronic signals: Fly - by - wire systems use electronic signals to transmit control inputs.
• Cable and pulley: Traditional aircraft control systems use cable - pulley mechanisms to transmit control inputs.
• Wind tunnels: Are used for testing aircraft designs, not for transmitting control inputs.
• Anti - torque pedals: Are a control input device (for helicopters), not a transmission method to control surfaces.

The load factor is the ratio of the lift force to the weight of the aircraft. During an approach to a stall, as the load factor increases (e.g., during a turn or when pulling back on the yoke), the stalling speed increases. This is because the lift required to maintain the aircraft's flight condition increases with the load factor, and the stalling speed is related to the square root of the lift coefficient. A higher load factor means a higher stalling speed.

Answer:

A. Hydraulic pressure, C. Electronic signals, E. Cable and pulley
