Thanks for that,
Sorry i didn' make myself very clear,
I am asking with regards to the age limit on a single engine, (C172), for training purposes, i have been told 6, 8, 10 and 12 years, a wide range of answers i agree.
I know they are limited to 2000 + Extension bringing it up to 2400hrs, so if i bought a C172 with say 700hrs left.. but how old is to old for training...Engine wise.
