The Royal Aero Club in Jandakot has formed part of the annual celebration since the event’s inception in 1985.
Pilot Gary Evans said his team tried to always do better than the previous year.
“We try to lift the bar each year so we bring more and more to the party – planes flying in formation, old-fashioned biplanes and skywriting, plus this year a display of high performance aircraft and aerobatics to dazzle and delight crowds,” he said.
The Aero Club will take advantage of 19 aircraft including 10 Cessna 152s, six Cessna 172s, two Tiger Moths and the Super Decathlon, which can fly upside down for two minutes.
Mr Evans said it was an exciting event, with more than 300,000 lining the banks of the Swan River.
“It’s a huge rush and the crowds make it all that much more special,” he said.
“Flying in formation over Perth with your best mates flying right beside you is a truly unique experience in itself.”
Planes will begin flying over the City of Perth by 3.30pm.
