Which items should be read back when an emended weight and balance is received?

The correct choice focuses on essential elements of weight and balance that directly affect flight safety and aircraft performance. When an emended weight and balance is received, it is crucial to read back items that inform the flight crew of the aircraft's loading and its implications on operational capability.

Stab trim, gross weight, and passengers are vital for determining how the aircraft will behave during flight.

Stab trim is important as it affects the control of the aircraft; ensuring that the aircraft is balanced is crucial for safe flight. Gross weight is a key factor that influences takeoff and landing performance, fuel consumption, and overall aircraft handling during different phases of flight. The number of passengers also impacts how weight is distributed within the aircraft, which is critical for ensuring that the center of gravity remains within acceptable limits.

In contrast to the other options, which focus on aspects that do not directly relate to the immediate weight and balance situation, this choice prioritizes critical elements that ensure the aircraft operates safely within its prescribed limits.
