The logging of instrument flight time refers to flight by the sole reference to intruments, ie no outside reference. Flight by IFR does not refer to the means by which the aircraft was safely navigated but to the rules under which it was governed at the time. Being as I am usualy way above 30,000 feet, I can usualy expect 10 or maybe 20 minutes at each end, of instrument flying, in a 7-8 hour IFR flight. If it was acceptable to log all IFR flight as instrument flight time I would have thousands. What would be the point of logging hours and hours of autopilot flight in the clear blue sky, drinking coffee and chatting with the hostess, other pilot and the boss, and proudly calling it FLIGHT BY THE USE OF INSTRUMENTS
