A/S Limit 1 Hydraulic Pump INOP value?

• A. 170 KIAS
• B. 150 KIAS
• C. 140 KIAS
• D. 180 KIAS

Answer: (A)

When a hydraulic pump is inoperative, you lose hydraulic boost and the flight controls become more sluggish. To ensure you still have adequate control authority, there’s a maximum airspeed you must not exceed with one pump inop. The published limit for this condition is 170 KIAS, which keeps enough hydraulic power available to maintain safe control without overloading the remaining system. Flying faster than this can reduce control effectiveness and make handling difficult. The other speeds are either well below the limit or exceed it, so 170 KIAS is the correct upper bound.
