Guernsey's eastern seafront is expected to be packed with spectators for the air display.
There are a number of aerobatic aircraft taking part, in solo and team displays.
The event is due to start at 11am with the Battle of Britain Memorial Flight, featuring a Spitfire and Hurricane.
The Lancaster Bomber that had been expected in the BBMF is no longer able to join the other WW2 fighters.
However, organisers say there will be a chance to see the Lancaster later.
Unfortunately, the Lancaster will not be displaying but it will do an overfly at around 2.45pm so you'll still have the chance to see her. ✈️

Their closing display is due to start at 12.45pm and will last around 15 minutes.
