Just back from a month on Madeira, regularly passed a windsock on a motorway bridge situated on the final approach to 05 at FNC. One day whilst driving by, I noticed this indicated a South Westerly of reasonable strength (10 to 15kts at a guess). Passing the airport viewing area a few minutes and no more than two miles later I noticed that the windsock adjacent to the 05 threshold was indicating a strong North Easterly. Then watched a JMC aircraft make a couple of interesting approachs and subsequent go-arounds before thinking better of it and departing. Saw almost the same thing on three other occasions during my stay. Fully aware that go-arounds are perfectly normal procedure, but they are rarely confidence inspiring for the passengers, especially somewhere with terrain like Madeira.. .. .I'm not qualified to comment on the safety aspects of operating commercial aircraft into the place, but as an experienced PPL and glider pilot I've seen enough to convince me that I wont be a passenger for Funchal again.
