IF time in log book? Reality time is time for let down.
If all flying done in South Africa then I take, for interview assess, 1/4 total time and 10 minutes for each hour. So..if TT = 4,000hrs, then 1/4 = 1,000hrs and 10mins/hr = 10,000minutes = 167hrs. With 167 hrs of let down practice, pilot should be pretty good. So..if he cannot fly let downs well with airmanship, then rest of log book hours are suspected. Therefore, no job. Damned simple.
