Re: Huh?
Pedant alert ...
You can't pass your PPL in a Cessna and fly a 747 the next day.
Actually, yes you can if you have the money. I believe it is technically possible to train for and get your PPL in a 747 - though the difference in cost between the per-hour cost of a light piston single and a 747 would make it a very expensive proposition.
Assuming you took the conventional route to your PPL (SEP(A)), you could still jump in a 747 the next day if you had the money to buy lessons for the type-specific qualification.
