The maximum speed for ADG operation is which value?

The maximum speed for ADG operation is which value?

• A. Vmo/Mmo (Max)
• B. 182 Knots Ground Speed
• C. 135 Knots (Min)
• D. 0.75 Mach

Answer: (A)

ADG operation relies on a steady airstream to drive a turbine and supply essential power. Because it must function safely within the aircraft’s certified envelope, its maximum operating speed is dictated by the airplane’s own speed limit: Vmo/Mmo (Max). This ensures the ADG only runs within speeds the airframe and system design are certified to handle. The other options represent fixed values not tied to the aircraft’s overall speed limit, or are speeds that aren’t about the ADG’s maximum capability. So the limit for ADG operation is the airplane’s maximum operating limit, Vmo/Mmo.
