National average is about 75-80 hrs.
Reasons are the very young and the very old and the very unmotivated.
Also a lot of people start/stop/start/stop their training, usually because of funding issues.
Part time training increases the news for repetition.
All that drives up the average.
Training in very busy airspace can lead to quite a bit of travel time to and from practice areas which reduces the ‘effective’ learning time in a lesson.
Let me break it down:
Start up and taxi 15 min
Checks in run up area 5 min
Travel time to practice area 15 min
Travel time back from practice area 15 min.
Single traffic pattern and landing and taxi and shutdown 10 min.
In a 1.5 hr lesson that leaves you 30 min effective practice and training time.
