Time to earn license for professionals

Hello all,

I just wanted to see if other CFIs and pilots have been seeing the
same trend I have. I've been flying with a student for a little over a
year now, and she's almost ready to solo. It will take her another
year to get her ticket, for a total of 2 years, and probably 100 - 120
hours total, when done. Why? Because she's a busy CPA, and sometimes
cannot fly for periods of up to a month. Obviously if a student pilot
hasn't flown for a month, much of the next lesson is simply brushing
off the rust.

I've talked to a couple other local CFIs about this, and they have
noticed a similar trend. As the cost of flight training has gone up
(schools near mine cost approximately $130-$140 per hour, wet, with
CFI), we have seen a seeming increase in the number of early mid-life
(30-50 years old) professionals (CPAs, lawyers, doctors, etc.) taking
lessons, because to them, money isn't a major issue. But TIME is. One
CFI told me he has been working with a well-known doctor for over 2
years, and he probably won't take his checkride for another 1-2 years,
simply because he cannot fly often. But, like my student, he really
DOES want to fly, and DOES want to get their ticket. I talked to my
student about this, and she's fine with taking 2 years.

So is this becoming a trend? Two years or more to get a PP-ASEL, start
to finish? And does this mean that it might be necessary to modify the
traditional PP-ASEL curriculum to better meet the needs of these
students?

Just wanted to hear what other thought.

Cheers,
