It was a fantastic treat to see the Prince, who celebrates his third birthday later this month, join in on the occasion. A spokesman for Kensington Palace said: "The Air Tatoo is a fantastic family-orientated event and the Duke and Duchess know that George will enjoy seeing the aircraft up close."
The royals were greeted by Air Marshall Sir Kevin Leeson, Chairman of the RAF Charitable Trust, and Air Chief Marshal Andrew Pulford, Chief of the Air Staff, RAF. They also met two members of the Red Arrows in front of a Red Arrow Hawk.
Shortly after their arrival, George was a little upset until Kate picked him up.
...And then it was time to look at the aircraft.
George was eager to step aboard.
The royals took a closer look at a Squirrel helicopter – the same aircraft the Duke trained in when based at RAF Shawbury in 2009.
"Daddy are you going to fly us?"
George was fascinated by the 'tail rotor'.
More from People:
"George, who wore noise-blocking ear protectors, pointed at planes in the sky, waved to visitors and seemed especially fascinated by the tail rotor of a helicopter. "I imagine his father has told him about helicopters, so he knew what that was called and kept saying, 'tail rotor.' It was good to see his technical knowledge! Some training going on early!" Flight Lieutenant Jim Hobkirk tells PEOPLE.
"They wanted to put him on the Duke's lap [at the controls], but he was having none of it. The Duchess suggested shutting the door to try to persuade him. But he was happy sitting with his mum." Hobkirk says of the young family, "They seemed very relaxed. The Duke said he misses flying and he wishes he could fly more and said he was envious of me."
William and George look at the aircraft on display.
George was very interested in the Red Arrow Hawk.
The Prince was eager to get in the cockpit.
For his first official UK engagement, Prince George appeared to be very much in his element. :)
George was given his own blue piggy bank.
The Cambridges have strong ties to the RAF, William having served with the search and rescue force at RAF Valley in Anglesey for over three years. In February, Prince Philip passed his patronage of the RAF Air Cadets down to Kate, who assumed the role of Honorary Air Commandant. The RIAT actually has a very strong connection to the Air Cadets. This year's event hosted official celebrations to mark the organisation's 75th anniversary.
Kate met a number of air cadets.
The Duke and Duchess chatted with television presenter Carol Voderman, who is an honorary ambassador for the cadets.
The event is staged in support of the RAF Charitable Trust, which was set up in 2005 to support the wider RAF family. As well as seeking to develop a spirit of air-mindedness in youngsters, it also aims to promote excellence with the Royal Air Force.
The Air Tattoo is the world's largest military air show, and last year featured 247 aircraft from 19 nations. The Air Tattoo's theme for 2016 is 'The Next Generation: Inspiring Innovation', offering visitors a display of cutting-edge aircraft technology both in the air and on the showground.
The thrilling event promises non-stop entertainment for all ages: "Fast jets, giant transporters, historic aircraft, and much, much more. There will be a chance to meet the crews, get close to the aircraft and enjoy a feast of first-class entertainment including the Techno Zone, an interactive showcase designed especially for youngsters, the Vintage Village, Autodrome and the Adrenalin Zone."
Showground attractions include the Autodrome with an array of automobiles. "There's more on offer than just supercars and classics though, once again the 'Get On' team will let youngsters over 12 taste the motorcycle experience with fully-trained instructors showing people the ropes in a safe and secure off-road area."
Vintage Village, allowing visitors a look back in time and a chance to revel in the fashion, jewellery and accessories of the 1940s. There's a vintage atmosphere with singing performances by award-winning artists clothed in authentic uniforms, not to mention tea and scones.
The showground map for the day.
Andy Armstrong, Chief Executive of RAF Charitable Trust Enterprises, who runs the airshow, was delighted to have the royal couple there:
"I'm particularly pleased for the 1500-plus Air Cadets who'll be on site either helping us run the airshow or taking part in the 75th celebrations - and for the 2,000-plus volunteers who work so hard to make this amazing event happen. To have the Duke and Duchess of Cambridge with us effectively rewards all their efforts with a Royal stamp of approval."
A royal wave from Prince George.
The trio posed for a photo with the Chinook Display team.
What did George think of the show? He gave it a royal thumbs up!
It was a day of repeats for Kate in the style department.
The Duchess wore her favourite Stella McCartney 'Ridley' dress, which she debuted during London 2012 and has worn several times since. Below we see Kate wearing it at the 'Aiming High' exhibition, during a tennis match at London 2012, and in Canberra during the 2014 tour.
The electric blue dress is from the Fall 2012 collection and was described: "A vibrant crepe dress. This simple shift embodies easy luxury with its minimalist silhouette and eye-catching bold hue. Concealed zip fastening at back. Round neck, short sleeves, darts at waist." It originally retailed for £515.
Another look at the dress on Kate today.
Kate teamed the dress with her navy Smythe One Button blazer.
Kate debuted it during the 2011 Canada tour and it's been suggested it may be a sartorial nod to the potential upcoming tour. The jacket is still available at Shopbop retailing for $595.
Kate selected her L.K. Bennett 'Floret' pumps for the day.
Kate wore the same Alice band which generated much chatter at Houghton Hall horse trials. For those hoping to Repli-Kate the look, J Crew has a very similar hair band.
She accessorised with her Kiki McDonough 'Lauren' earrings.
And her Cartier Ballon Bleu watch.
Prince George looked adorable in his white polo shirt, shorts and Trotters Nantucket Canvas Shoes (with thanks to What Kate's Kids Wore for the info on his outfit).
The blue sticker on George's T-shirt was from 2014, which celebrated the 50th Display Season of the Red Arrows.
George's earmuffs are the Baby Banz Infant Hearing Protection Earmuffs. They are available at Amazon for $29.

In this video you can hear Prince George speak when he's given a sticker.
It was a lovely engagement and such a surprise to see Prince George with his parents on an official appearance. We leave you with a memorable shot from the visit.
Hope you all have a great weekend :)
