As a former air ambulance pilot in East Anglia, Prince William is passionate about supporting the emergency services in all their forms. He has been a patron of the charity for four years and took to the air in one of the organization’s helicopters to mark the 30th anniversary of the service.

Prince William isn’t expected to make any more public appearances for more than a week as he continues to focus on his wife’s health and helping care for the couple’s three children:Prince George, 10,Princess Charlotte, 8, andPrince Louis, 5. Next week is the children’s half-term vacation from school.

Aroyal source tells PEOPLE exclusivelyin this week’s issue that the Prince of Wales is inregular contactwith his father amid the news of the King’s cancer diagnosis. As King Charles steps back from public engagements and Princess Kate continues hermonths-long recuperation, it’s up to Prince William (along with Queen Camilla) to be the face of the monarchy.

“It is hard with Kate being ill as well, but he will step up,” says a source close to the royal household.

“He wouldn’t want to put that pressure on William,” says the source. “He has always wanted to save his children from having that pressure too early and that will remain. Particularly as William has other priorities [with Kate].”
