Former British Army helicopter pilot Prince Harry will be doing what he does best. He will take his position in the fighter aircraft on Sept. 15. The 30-year-old royal will take to his royal duties at the Battle of Britain’s 75th anniversary flypast.

The qualified helicopter pilot is expected to be in the back seat of the lead fighter, from where he can fly the dual-controlled plane. His royal engagement date coincides with his 31st birthday, Hello reported. The Spitfire flypast is scheduled to be held at Goodwood Aerodrome, just down the Sussex coast.

However, the fourth-in-line to the British throne will spend his big day by participating in a cause close to his heart. Kensington Palace confirmed Harry’s royal duty in a series of tweets on Wednesday. “Prince Harry to join @endeavourfund scholars during a #BoB75 Anniversary flypast @boultbeeacademy on 15 Sep. Flypast will bring more BoB aircraft together since #WW2, as a show of thanks from this generation to 'The Few’”.

The prince will join scholars from Endeavour Fund, which was set up in 2012 under the aegis of the Royal Foundation to support the recovery of wounded and sick service personnel. The charity was founded by the Duke and Duchess of Cambridge that is Prince William and his wife Kate Middleton, along with Prince Harry.

This will be Harry’s second trip in a Spitfire. Earlier this year he took to the skies in a secret flight, again over Goodwood, to launch a Spitfire training scholarship for wounded servicemen.

The event is being organized by the Boultbee Flight Academy. Around 40 Spitfires, Hurricanes and Blenheims from across the U.K., U.S. and Europe will take part in the flypast over the South of England.

A royal insider said that Harry was determined to participate in the event. “He has put so much into it; he wouldn’t want to miss it for the world.”

The prince will reportedly work as a volunteer with the Personnel Recovery Unit of London district this fall. He will also visit America, South Africa and Lesotho as part of his official duty later this year.

Harry is currently on a three-month long visit to South Africa. He is spending his summer carrying out conservation projects in Southern Africa.
