Raw data flying.
It depends on your airlines policy and whether your Captain will allow you. Most airlines dictate when you can and cannot hand fly or with or without the Flight Director. If it is a high workload sector your Captain has the right to refuse if it is going to load him up as I often did. As stated by previous replies, most times you are vectored towards the localizer or the Initial Approach Fix(IAF). If the airspace is busy you could also be denied the request for a procedural(full let down) approach. Most times you are late or trying to save fuel so a full let down is not an option.
