What does PAS stand for in the UH-60S aircraft?

• A. Power Available Spindle
• B. Power and Sensor
• C. Pressure Available System
• D. Position Adjustment System

Answer: (A)

Power Available Spindle is the idea behind PAS here. In the UH-60S, PAS refers to the part of the drive system that communicates the amount of engine power that can be delivered to the main rotor through the transmission. This helps the crew gauge whether the current rotor load can be met without overloading the engine or losing rotor speed, especially during high-demand maneuvers. The other options describe different concepts (general power and sensing, hydraulic pressure, or positional adjustments) that aren’t what PAS denotes in this aircraft.
