I agree with showtime, Simulator does help it a lot and IMHO, I learned it by myself, and experience tells many things, and ofcourse a little bit briefing helps him a lot, regarding use of rudder, elevator and linning up while landing, once the plane touches the ground, elevator stick should be back to neutral position, I think your dad would do it good, naturally it would take him sometime, cos, things don't change overnite, I hope he is gonna do good after few flights and with some encouragements.

Good Luck
