As to the first one, it has to be the wing. The other important parts (elevator, flaps, ailerons, propeller) work to help keep the plane up once it gets airborne, but the wings work on the lift portion to help with the climb portion

where can you find the Faa violations when you required to work on engines of an Etops aircraft w.g.A330-200?

CAP pilots can assist you get some practice (even training if they are a CFI) -

One advice, stay away from "flight simulator games" -
These can do you more wrong than good training -

I would recommend an organized private`pilot course -
Rather than bits and pieces here and there which is rather questionable -
CAP pilots can give you the private pilot theory and assist you -

Do not imagine, you will get your license with "45.1" hours flight time -
The average in USA is about 60-65 hours -

Do you knowledge (written tests) when you are age 16...
They are valid for 24 months -

The average cost of the private pilot training is $10,000 in USA -
But with what you may get "free" here and there, you will save 2 or 3,000 -

There is no such thing as a "cheaper program" in aviation -
Cheaper is not in the vocabulary, except pilot salaries and benefits -

The tuition for the airline transport pilot licence (ATPL) is about £80,000 -
Training takes about 16 months -
Further qualifications are sometimes desirable for additional tuition -
Such as type ratings on A320 or B737 airplanes -

The airline pilot licence is NO guarantee of airline pilot employment -
Your pilot career might be limited to sightseeing flights with an aero club -

Banks do not loan tuition for pilot training -
Too many pilots find themselves unemployed and fail to repay the loans -

The major problem with pilot employment is the small number of pilot vacancies -
And the large number of qualified candidates -

Many UK pilots make a career abroad, in EU or the rest of the world -

Various reputed flight academies in UK are:

yeah. for all purposes, it's just a throttle up from "ground idle" to "flight gov" or whatever the manufacturer calls that.

all helicopters (even the RC ones that have more than 2ft rotor diameter) HAVE TO work within certain range of rotor RPM. it's simpler to control the power that way.
