ATC History - The One-in-One Recovery
The One-in-One recovery was a flame-out procedure that suited the Hawker Hunter. if a pilot was unlucky enough to have an engine failure he would be given a vector and instructed to 'convert excess speed to height and pass height with all transmissions'.
When the pilot's range (or track distance to be more precise) in miles equalled his height in thousands of feet (i.e. 8nms at 8,000') the pilot was instructed to lower his undercarriage, which would then increase his rate of descent to 1000'/nm - or 'one-in-one'.
Perhaps a VV would manage one-in-one "clean" !
Danny.
