The right training plane is the Cessna 150 / 152 series.

Ask any airline captain, what plane did you learn on? Unless he / she learned in the military, the answer will be "Why, of course it was a 150".

The many advantages of a 150 / 152

Very easy to fly - so you can learn to fly without getting involved with complex engine, aircraft and navigation systems.
Very slow - so instructors can talk you through maneuvers without having to grab the controls. Letting one learn by doing!!
Very - Very strong. Great for learning how to land (when not all the landings will be smooth).
Very stable in flight - so instructors can let you learn without having to worry about getting into a bad situation.
Very dependable in a learning environment - simple things "don't brake"
For those concerned about expenses, these are about the least expensive planes to own and operate per month and per hour. One can buy, fly and sell for the same price.
Great to build time for obtaining the instrument rating (needed to get the plane from being a hobby to a transportation machine).
Great to become comfortable in the air so one can easily transition to complex travailing machine.
Great for mature people who are naturally more apprehensive, due to its simplicity and “not to sensitive - not to sluggish” feel.
