but recall somewhere between 15 and 18 gph in those days (??).
Kept a record of fuel flows on a ferry from Lord Howe to Palmerston North, the IO720's installed in QueenAir VH AEQ were returning 14.2 port and 14.5 gph stbd at FL170. The aircraft was then used on the Chathams Island run. The IO720's performed very well on this task.
