Without pre-empting the subsequent enquiry, what does seem apparent is that the pilot took off at about 0630hrs, so presumably her duty time clocked-on at 0600hrs, and she was scheduled to finish flying at 1930hrs, presumably clocking-off duty at 2000hrs. Flying remote area survey out in the hot dessert, low level, and quite possibly close to or at max AUW, and after 13+ hours of duty time, that's alot for a Chief Pilot to ask of any pilot, let alone an inexperienced one. But in any event, surely an elapsed duty period of 14 hours can't be legal? What gives?
