Defending champion Paul Bonhomme of Britain was on top of the timesheets in both training sessions on Friday ahead of the Red Bull Air Race Qualifying session on Saturday.
He finished ahead of Martin Sonka in T1 and Nigel Lamb in T2, under brilliant blue skies and a large crowd of spectators along the Polish coast.
Bonhomme, who is second in the 2014 championship behind Austria's Hannes Arch, mastered an extremely difficult 270-degree turn halfway through the track that has been set up on the choppy waters of the Baltic Sea just off the beaches of Gdynia – made more challenging by strong headwinds. Bonhomme stopped the clock with a time of 1:11.354 seconds in the second session, after posting1:12.066 first time around.
"It's a really lively track but interesting track and a lot of fun to fly," said Bonhomme. "I think it's good to have a turn like that. It's what we've been asking for. It makes it a pilot's track rather than just relying on engines and aeroplanes. If you make the track really tricky and interesting, it brings it down to the pilots' skill."
