It depends a lot on the height of the structures in the rotating cylinder. In addition, flying from the zero-g center to the rotating edge would be suicidal unless you had a very high flight speed. For example, a 5 km radius object rotating fast enough to mimic 1g would have a tangential velocity of 221 meters per second (roughly 440 mph). For most fliers to safely descend, they would need to gain velocity by descending in stages. If they have a g-limit to their flight, it would mark the point where their glide becomes a plummet, as the winds would become to extreme for them to handle.
