Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

How are scenes wherein the characters have a dialogue inside a helicopter as well as interact with the environment outside it, shot? Do they use drones for this, or is the dialogue shot separately on the ground and the rest of it shot midair with overhanging cameras? For example: The one in Narcos S2E3 or the one in Narcos S1 where Gacha is shot, or any of the numerous helicopter scenes from Avatar.
