I noticed that small livery changes are often done without a dedicated update from the App Store. Is it possible for IF to add new aircraft or new features using the same method?
Similar updates such as the navigation database is done like this. Larger features like an aircraft, however, I am unsure of.
New aircraft, I’m not too sure about. Features, maybe. It depends on what it is.
If you consider adding scimitar winglets and different engines to an aircraft as a feature, I guess so. For example, they did this for the United B752. There may be a capped size, though.
