What is the maximum linear load also known as?

The maximum linear load is recognized as the maximum permissible floor running load. This term refers to the maximum weight that can be safely distributed along a specific linear section of the aircraft's floor without compromising structural integrity or safety. Ensuring that this load does not exceed the established limits is critical for maintaining the aircraft's balance and preventing potential damage or failure of the floor structure during flight.

The other terms listed do not accurately reflect the same meaning. For example, the peak running weight might suggest a maximum total weight but doesn't specifically refer to the linear distribution aspect. Maximum cargo distribution typically relates to how cargo is loaded within the overall weight limits, without focusing on the linear weight on the floor. The linear weight limit could imply a weight boundary, but it lacks the official and safety-related nuance that comes with the term 'maximum permissible floor running load.' Thus, understanding the correct terminology is key in the context of mass and balance in aviation.
