On the northbound leg of the airbridge there were numerous ways of approaching to ASI due to the lack of ATC control in the South Atlantic. Some crews kept the wind on the tail (zero drift) as far north as possible putting them closer to South Africa than South America. Others cruise climbed gently as weight and temperature allowed. I always kept a Last Point of Diversion (LPD) to Recife in my back pocket when ASI weather was iffy. The famous story of the return to ASI by one eyed B*** A****** when the weather clamped is recorded in another thread but after using up all his "Island Holding" fuel he briefed "In the event of a go round on this approach I intend to crash in the sea along the line of the beach while the engines are still turning" they saw the approach lights. It wasn't always beer and skittles on the return half.
