When are wheelchairs typically removed from an aircraft due to weight and balance issues?

The correct approach to understanding when wheelchairs are typically removed from an aircraft involves recognizing that operational protocols prioritize safety, weight distribution, and passenger needs. Specifically, wheelchairs are generally removed based on weight and balance considerations, which means that if an aircraft is at or near its capacity, additional weight may need to be minimized to ensure that proper balance and safety are maintained during flight.

In practice, wheelchairs may be removed from the aircraft in accordance with specific airline policies and the overall operational discretion of the flight crew. If a situation arises where the weight limits have been reached, the crew will need to assess how to safely manage the extra weight and balance. This decision is typically at the discretion of the flight crew based on the guidelines they follow, the aircraft's specifications, and the specific scenario at hand.

Understanding this context helps clarify why the correct answer is based on the flight crew's responsibility to ensure passenger safety and operational integrity rather than a fixed protocol that could lead to oversight regarding individual passenger needs or aircraft performance.
