Here are the straight answers on choosing what helicopter to train in.
If you want to obtain your PRIVATE helicopter rating:
It doesn’t really matter what you train in, although I would push for learning in whatever model you intend to fly/rent/purchase if possible.
National average is 60-70 hours to obtain a private rating in an R22 (with no flight experience).
The R44 is closer to the FAA minimum of 40 hours.
Other aircraft tend to run 40-50 hours.
How many hours it really takes, depends on you!
If you want to obtain your COMMERCIAL rating and become a FLIGHT INSTRUCTOR, the normal career path today:
Because the Robinson Helicopters are by far the most popular worlwide it is really a benefit to get time in them. You don’t have to do ALL your training in one, but you certainly can. There are a few special regulations that go with Robinsons, and I’ll explain those below.
As a licensed helicopter pilot, to act as Pilot in Command of a Robinson R22 or R44 you must receive 10 hours of dual instruction in the aircraft. Simple enough.
To act as a Flight Instructor in an R22, you must have 50 hours of flight time IN AN R22 and an endorsement from a D.E.
To act as a Flight Instructor in an R44, you must have 50 hours of flight time in an R44, or 25 hours R22 + 25 hours R44 and an endorsement.
To act as a Flight Instructor in a Schweizer 300, Bell 47, Enstrom F28C, MD500E, etc, etc, you must have 5 (FIVE) hours in that aircraft.
So if you learn to fly in a Schweizer, then try to get a job at a school that has Robinson, you will need to fly the 50 hours extra.
