That would fail around 99.99 percent of all airline pilots....
Come on now - be realistic with those tolerances.
Ummmm, not really. I went from flight school to instructing (for 18 months) to large biz jets. 8-9 months later I rented a warrior and passed these requirements straight away.
As for what to do to prepare for instructing... I can only repeat what mrmum said. I'll just add that it's good to continue in this vein after you've got the instructor rating. I remember the shock of finding a fellow instructor who wouldn't take students to new airfields because he was wary of unfamiliar situations. IMHO exposing yourself to unfamiliar situations prepares you for more unfamiliar situations which is 50% of airmanship (the other 50% is being well prepared for what you expected to happen) Oh yes, and doing this means you'll never lose your passion for flying. When every day's a school day it never gets boring.
