Sure, a piece of paper was given to me which said it 'might take more' but 45 is what I heard.
Expanding on a thought...
PPL candidates: If an examiner gives you a license after a successful flight test - you are a pilot, but you are not at all an experienced pilot. You have demonstrated the
minimum skill set to pass the test.
YOU - not the flying school, were and remain responsible for assuring that you seek out the required training. Yes, you rely upon the school to lead the path, but you should take responsibility too. Blaming the school 'cause you did not learn something well is a cop out. The skills of piloting "well" take hundreds of hours, 45 is a
minimum. You must know that, and keep skill building, both solo and dual - even after PPL.
An hour a month -with no Ipad - is a minimum for skills maintenance for a new pilot -
if that hours is skills practice, rather than a $100 burger run. If you want to be a skilled pilot who flies in for an airport burger, you should plan on two hours a month flying, with the second hour being the Ipad cross country burger run flight.
To maintain your skills fly the circuits and the abnormal/emergency practice with as little cockpit distraction as possible - eyes out as much as you can manage. Put the cockpit toys away for the circuit or the Hasel zone, they won't help you while you're learning and
flying skill building.
If your school lets you fill the cockpit with gadgets and cords for your circuit and practice area work, they are not doing you any favours! You need to fly airspace aware - so take a folded properly chart, all us old pilots managed okay with just a chart, and flying has not changed that much!
