concerns about whether the average pilot has enough physical strength to manually crank a flight-control wheel in extreme emergencies.
Back when the type first flew, airline pilots were almost entirely male now we have dainty 45kg females on the flight deck, the concerns shouldn’t be about the average pilot but must be about the weakest pilot flying the aircraft. Most women would be unable to fly a B707 which required physical strength, particularly with engines out or boost systems inoperative.
This further shows how outdated the type is when most other manufacturers are using modern FBW control systems where pilot strength isn’t a requirement. A teenage girl could easily cope with the control force requirements on an A320.
