Flying hours is a poor indicator of flying abilty. Attitude, personality, and common sense are important atributes for a flying instructor but difficult to detect on the basis of a short written text. Teaching the PPL skill set is not rocket science and well within the capabilties of a realtively low houred CPL. The important thing for the new instructor is to park their ego at home and realise just because they finished the integrated course and have frozen ATPL they still have alot to learn about flying. They also have to be prepared to work very hard because in the early days the instructor prelesson peparation is vital to ensure the PPL student gets their monies worth.
