Which trim on the T-54A is designated as antiservo?

The trim designated as antiservo on the T-54A is the elevator. In aircraft control systems, an antiservo trim surface is utilized to counteract the effects of a primary control surface, in this case, the elevator. The primary purpose of the elevator is to control the pitch of the aircraft. When deployed, the antiservo trim surface works in opposition to the elevator, adding stability and preventing over-controlling.

In other aircraft systems, antiservo surfaces are commonly used to enhance control and stability, particularly in high-speed flight where control responsiveness can lead to instability. The elevator trim allows pilots to maintain desired pitch without needing to exert continuous pressure on the control yoke.

Understanding the role of antiservo trim is crucial for effective aircraft operation, especially in maintaining smooth and controlled flight dynamics.
