SNS3Guppy, thanks for the detailed reply.
Following your comments, I can see that the 'turn technique' (for want of a better phrase) used by an Airbus A320 pilot to line up will be different from the technique used by a Boeing 747 given the difference in size, shape, position of landing gear on their respective aircraft.
But I wondered how you know when to make the turn? Do you have a visual reference point on the runway? For example, you start the turn when you reach the second stripe after the centreline? Slightly crass analogy, but when you learn to drive and to do a reverse parallel park, you learn to turn when the car passes a certain point. Is it similar?
Is it any more difficult in reduced visibility, for example at night or in fog? From a previous thread, I remember that some types (e.g. B777) have external cameras with monitors on the flight deck, which must help.
