  1. Your Logo Here UH-60 Mixing Unit, Electronic Coupling, & Stabilator • Purpose: Develop the student IP’s understanding • of the components and functions of the Mixing • Unit, Electronic Coupling, and the Stabilator • References:UH 60 -10 and 23-1, Flight Line Supplement, Student Handouts, TC 1-212

  2. Overview • Mixing Unit • Collective/Airspeed to Yaw (Electronic Coupling) • Stabilator System • Questions

  3. Been there, done that, got the coffee cup...

  4. Mixing Unit • Functions • Collective to Pitch • Collective to Roll • Collective to Yaw • Yaw to Pitch

  5. Collective to Airspeed to Yaw • Electronic Coupling • Function of the SAS/FPS computer • Increases or decreases T/R pitch with the Yaw trim actuator

  6. Stabilator Components • Control Panel • #1 and #2 Stabilator Amplifiers • #1 and #2 Stabilator Actuators • Position Transmitter/limit Switch Assembly • Airspeed and Air Data Transducers • #1 and #2 Lateral Accelerometers • #1 and #2 collective Stick Position Sensors • Cyclic Mounted Stabilator Slew Up Switches • Stabilator Position Indicators

  7. Stabilator Components

  8. Stabilator FunctionsS.C.A.L.P. • Sideslip to Pitch coupling • Collective Coupling • Angle of Incidence Decreased w/ Increased Airspeed • Low Speed Flight it Aligns w/ Rotor Downwash • Pitch Rate Feedback

  9. Stabilator Malfunctions • STABILATOR MALFUNCTION - AUTO MODE FAILURE • UNCOMMANDED NOSE DOWN/UP PITCH ATTITUDE FAILURE.
