jackson,
The AFT add-on training might be likened to turbine training at the end of a 100 hr program. It of course costs a little more but you must decide if it might pay off or not.
John at AFT is sold on the reliability and performance of the Robinson 22 and 44 so chooses to offer the 44 endorsement c/w sling, bucketing, mountain exposure to round-out the licensee's skill set a litlle and to remove some of the surprise down the road when one of his graduates is on the job and suddenly asked to longline a load ect ect.
I can say that the mountain flying (bush camp) and 100 ft line each greatly contributed to my confidence in flying as well as removing some of the unknowns I anticipated encountering down the road. You know these additional skills have been added to my resume as well.
John does not feel comfortable sending minimally trained students out the door so really prefers not to flog a 100hr course. Another example of this are his type endorsements. If you as a lowtimer are counting on an endorsement for 3-5 hours of flight time, John will likely send you away. He prefers to provide something at little more comprehensive (ie. 10hrs+/-) to be certain the student is going to survive their next 100hrs of work.
I am happy having chosen to pay the extra $ for these specific skills.
