An autonomous station on a Lisbon terrace — photographing, measuring and publishing every aircraft on final approach to LPPT, without any human input.
LPPT's runway runs SSW–NNE. The wind decides which way traffic flows. With a north wind, aircraft approach from the south — descending over the Tejo and the city centre before touching down on RWY 03, crossing directly over my terrace on final approach. With a south wind, they take off on RWY 21, climbing towards the SSW, crossing the terrace before reaching the Tejo.
