The airport was once infamous for its short runway which, surrounded by high mountains and the ocean, made it a tricky landing for even the most experienced of pilots. The original runway was only 1,400 metres in length, but was extended by 400 metres after the TAP Air Portugal Flight 425 incident of 1977 and subsequently rebuilt in 2003, almost doubling the size of the runway, building it out over the ocean. Instead of using landfill, the extension was built on a series of 180 columns, each being about 70m tall.
For the enlargement of the new runway the Funchal Airport has won the Outstanding Structures Award, given by International Association for Bridge and Structural Engineering (IABSE). The Outstanding Structures Award is considered to be the "Oscar" for engineering structures in Portugal.
