I'd like to know
How many hours do you need?

Its based off hours in the air, so it really depends on you

There r other things involved other than in air time. Ground school must be completed & for the most part this depends on classes running etc. In Canada anyway u also have to write ur PSTAR, pass the nav canada ground school exam, radio exam, & then the flight test. Of course air time is a major component but all of the ground work does take considerable time.

l completed my training in 6 weeks. l am of the opinion that u really can not do it any faster (give or take a weee little) than this with no previous experience. l ate/slept/talked/dreamt aviation for the entire time doing studying/training full weekends, evenings etc with about 1-2 hr downtime a day. l think the expectations of my course were a little tougher than the normal but .. . .

It depends on how much ur into it. Ive had a really extremely committed student who finished in 49 hours & Ive had students that took over 130 hours. But hours aside the FAA mandates that u need 40 hours (Broken in to specific sections, refer to FAR part 61 for more info) to qualify for a Private ticket. l always tell people that want to learn to fly that the best thing that they can do is a course by Sportys, King Schools, or Jeppessen & read as much as u possibly can before even stepping foot inside the cockpit. This will save a lot of money & time!!!
