I want to know the answer to the following question:
What term is used to describe the altitude for a gun to shoot shells against a target that is moving?
All the background I'm provided with is that "The British adopted "effective ceiling", meaning the altitude at which a gun could deliver a series of shells against a moving target; this could be constrained by maximum fuse running time as well as the gun's capability.". Is that enough to answer the question?
Answer: yes
